BS EN 12635 for UK Industrial Door Owners
A heavy industrial door can become a serious workplace hazard when its safety devices, fixings, or controls fall into disrepair. BS EN 12635 helps owners understand what should happen after an industrial, commercial, or garage door arrives on site.
For warehouses, factories, retail units, garages, and service yards, the standard gives practical guidance for installation, operation, maintenance, repair, and eventual removal. It also helps you ask better questions of installers and maintenance providers.
Key takeaways for door and shutter owners
- BS EN 12635:2002+A1:2008 covers the installation and use of industrial, commercial, and garage doors and gates, including manually operated and power-operated products.
- The standard isn’t legislation. However, its guidance supports wider duties to keep workplace equipment safe, maintained, and suitable for use.
- Handover documents, operating instructions, safety-device details, and service records give owners evidence of how a door has been managed.
- Inspection frequency should reflect the door’s type, traffic, environment, manufacturer instructions, and risk assessment. A busy powered shutter needs closer attention than a lightly used manual store door.
- A door with a failed safety edge, damaged guide, unreliable brake, or uncontrolled movement should stay out of use until a competent engineer has assessed it.
What BS EN 12635 covers
The full title is BS EN 12635:2002+A1:2008, Industrial, commercial and garage doors and gates, installation and use. The BS EN 12635 scope includes doors used for vehicle, goods, and pedestrian access, as well as rolling shutters and grilles in commercial settings.
It is part of a wider family of door safety standards. Therefore, owners should not treat a single document or service sticker as proof that every safety risk has been addressed.
Information at installation and handover
The standard expects manufacturers and component suppliers to provide enough information for safe installation and use. In practice, this should include operating instructions, warnings, maintenance guidance, identification details, and information about installed safety devices.
At handover, keep these documents with the building’s health and safety records. If a property changes hands, pass them to the new responsible person rather than leaving them in a drawer beside an obsolete control panel.
Manual and powered doors need different controls
A manual shutter still has risks. A damaged curtain, worn spring, poor locking arrangement, or loose guide can cause injury or compromise site security.
Powered doors add moving-force hazards. Motors, brakes, remote controls, push buttons, photocells, pressure-sensitive safety edges, and emergency releases all need to work as intended. The HSE update on powered-door standards also points owners towards BS EN 12453:2017 and BS EN 12604:2017, which address safety in use and mechanical safety for powered systems.
BS EN 12635 and your legal duties
BS EN 12635 is a British Standard, not a law in itself. Still, it provides a useful benchmark for safe installation, handover, operation, maintenance, repair, and dismantling.
Workplace owners and employers also have wider responsibilities. Under PUWER, doors and shutters used for work are work equipment. They must be suitable, maintained in a safe condition, and inspected when deterioration could create a risk.
A site with a roller shutter used by forklift traffic several times each shift has a different risk profile than a manually operated shutter on a rarely opened store room. That difference should affect inspection and maintenance planning.
A maintenance visit is not a substitute for daily awareness. Staff should report unusual noise, erratic travel, visible damage, or a safety device that no longer reacts properly.
For a closer look at workplace duties, see this guide to PUWER roller shutter compliance. It explains why inspection records and prompt defect reporting matter for commercial shutters.
Put one person in charge of each door group
Responsibility often becomes unclear on multi-tenant sites, busy depots, and premises with several entrances. Assigning a named manager or supervisor prevents safety issues from being passed between facilities teams, landlords, and contractors.
That person doesn’t need to repair doors. However, they should know the location, make, operating method, normal use pattern, emergency release method, current defects, and servicing history for each door.
Start with a usable risk assessment
A written risk assessment should consider the people and vehicles around the opening. Look at pedestrian routes, forklift movements, delivery schedules, pinch points, visibility, weather exposure, and whether children or visitors can reach the controls.
A high-speed door between temperature-controlled production areas may need frequent checks because it operates many times a day. An insulated roller door with foam-filled, double-skinned steel laths may help with heat retention and security, but its motor, curtain, guides, and safeguards still need attention.
Make routine operator checks practical
Operators should be able to identify obvious faults without dismantling the door. Before use, they can check that the opening is clear, controls respond correctly, and the door travels normally.
Monthly written operational checks are often sensible for powered equipment. Warwickshire County Council’s powered-door guidance recommends intervals of no more than one month unless the manufacturer’s manual says otherwise. Your own schedule should follow the higher risk found on site.
Keep records that tell the full story
A paper or digital record should make it easy to trace what happened to a door. It also helps an engineer diagnose recurring faults, such as repeated curtain misalignment or a safety edge that fails intermittently.
HSE does not impose a universal legal requirement for a maintenance log. However, records are sensible for higher-risk work equipment, and BS EN 12635 practice commonly includes a log book for power-operated doors.
Record the door’s identity and safety features
Start each record with the door’s location, manufacturer, model, serial number, installer, handover date, and responsible person. Add photographs if identification plates are faded or difficult to reach.
List fitted controls and protective devices as well. That may include photocells, light curtains, safety edges, hold-to-run controls, emergency stops, warning lights, manual overrides, and bottom-edge protection.
Record work, defects, and retesting
Each service entry should state the date, engineer, work carried out, defects found, parts fitted, tests completed, and any limits placed on use. If the engineer recommends a repair or safety upgrade, record who received that advice and when.
Good records also show that issues were closed properly. For example, a note saying “safety edge replaced and tested through full closing cycle” is more useful than “door repaired.”
Plan maintenance around real use
There is no universal service interval that fits every industrial door. Manufacturer instructions, environment, cycle count, age, vehicle exposure, and the consequences of failure should shape the schedule.
For many commercial sites, annual servicing is a sensible minimum starting point. However, a door used heavily throughout the day may need inspection every six months or more often.
Include the whole operating system
A competent service should look beyond the curtain or door leaf. Engineers should check guides, fixings, barrel assemblies, springs, cables, chains, motors, brakes, travel limits, locks, controls, and electrical connections.
Powered shutters also need functional tests of protective devices. A sensor that appears clean can still be misaligned, disconnected, or incorrectly configured. Use planned roller shutter inspections to identify wear before it causes an unsafe closure or prevents access.
Upgrade equipment when repairs expose a risk
Older shutters may lack suitable bottom-edge protection, reliable emergency controls, or modern sensing equipment. Repairs can be an opportunity to correct recurring hazards rather than restoring a weak arrangement.
If a site assessment identifies gaps, consider upgrading shutter safety devices. Better controls, improved stopping points, safety edges, stronger guides, and dependable manual override arrangements can reduce avoidable risk.
Take dangerous doors out of service
Stop using a door if it drops, jerks, overruns its limits, fails to stop, has damaged guides or slats, exposes loose cables, or has a defective safety device. Keep people away from the opening and use an agreed alternative route where possible.
Do not ask staff to hold a faulty shutter in place, defeat a sensor, or operate a door by repeatedly pressing controls. These actions can turn a manageable fault into an injury or major property damage.
Secure the area, isolate power when it is safe to do so, and arrange a competent inspection. Where the opening leaves stock, vehicles, or premises exposed, emergency industrial door repairs can restore security while the fault is dealt with properly.
Frequently asked questions
Does BS EN 12635 apply to roller shutters?
Yes, it applies to commercial rolling shutters and rolling grilles within its defined scope. It also covers industrial, commercial, and garage doors and gates used for access by people, vehicles, and goods. Check the product documentation if you have an unusual installation or specialist barrier.
Is BS EN 12635 a legal requirement?
The standard itself is not legislation. However, following its installation and use guidance can support a safer system and help meet broader workplace equipment duties. Site-specific risk assessment, maintenance, and competent repairs remain necessary.
How often should an industrial door be checked?
The correct frequency depends on use, location, equipment type, manufacturer instructions, and risk. Busy powered doors near pedestrians or forklift routes usually need more frequent attention than lightly used manual doors. Arrange commercial door safety inspections on a schedule that reflects those conditions.
What should I do after a door repair?
Ask for a clear record of the fault, repair, replacement parts, tests, and any remaining recommendations. Update the door log, brief relevant staff, and confirm that safety devices work before normal operation resumes.
Keep compliance practical and visible
BS EN 12635 gives industrial door owners a clear framework for safe handover, operation, maintenance, and repair. The strongest protection comes from pairing that framework with a risk-based inspection plan, useful records, and fast action on defects.
A safe door is one that staff can operate confidently, managers can account for, and engineers can inspect without missing its history. For help with servicing, repairs, or a site assessment, Contact Us.
BS EN 12604: A Practical Guide for Industrial Door Owners
A heavy industrial door can create serious risk when a spring fails, a guide bends, or a curtain drops without warning. BS EN 12604 gives owners a clear reference point for the mechanical safety of industrial, commercial, and garage doors.
For a warehouse, shop, factory, or loading area, the standard matters because doors often operate close to staff, customers, vehicles, and stored goods. Knowing its limits helps you ask better questions during installation, servicing, repairs, and upgrades.
Key Takeaways for Door Owners
BS EN 12604 focuses on mechanical safety. It deals with how a door moves, stays supported, and avoids creating crushing, trapping, shearing, or falling hazards.
Keep these points in mind:
- The standard covers mechanical requirements and test methods for industrial, commercial, and garage doors and gates.
- It applies to more than powered doors. Manual roller shutters, rolling grilles, sectional doors, and vertically moving doors can also fall within its scope.
- A compliant installation still needs planned inspection, maintenance, and prompt repairs.
- BS EN 12604 works alongside other standards, including EN 13241 and BS EN 12453.
- Owners should retain service reports, fault records, repair details, and handover documents.
A door that still opens and closes may have a safety fault. Worn cables, damaged guides, weak springs, and failed anti-drop devices can remain hidden until the door is under load.
What BS EN 12604 Covers
The full title is “Industrial, commercial and garage doors and gates, mechanical aspects, requirements and test methods.” The current UK listing is BS EN 12604:2017+A1:2020, which includes the 2020 amendment.
The standard considers doors and gates within reach of people that provide access for goods and vehicles, including vehicles driven or accompanied by people. Its purpose is to reduce hazards created by the door’s mechanical parts and movement.
Doors commonly within scope
Industrial roller shutters, sectional overhead doors, rolling grilles, up-and-over doors, and many garage doors may be covered. The standard also includes manually operated vertically moving commercial doors, such as shutters and grilles used mainly to protect goods.
For a busy warehouse, an electric roller shutter is often practical because it allows faster pallet movements and reduces manual handling. However, automation adds safety devices and controls that need regular testing alongside the basic mechanical system.
Important exclusions
BS EN 12604 does not apply to every type of entrance. Pedestrian doors, vehicle doors, dock gates, lock gates, railway barriers, and doors that form part of a building’s load-bearing structure sit outside its scope.
That distinction matters when reviewing risk assessments or ordering a replacement. A fire door, for example, may need additional fire-performance requirements that BS EN 12604 does not cover.
The Mechanical Risks BS EN 12604 Addresses
A large shutter curtain or sectional door stores significant energy in its springs, counterbalance equipment, drive system, and moving panels. The standard addresses how those parts behave in normal operation and during foreseeable component failures.
Controlled movement and stability
A door should move predictably through its full travel. It should not bind in the guides, run unevenly, twist on its barrel, or need excessive force to operate. Tracks, hinges, brackets, cables, springs, shafts, and fixings all affect stable movement.
Owners should pay attention to changes in sound or speed. Grinding, scraping, jerking, delayed stopping, or a curtain that sits unevenly are all reasons to isolate the door and arrange inspection. The most common roller shutter repair warning signs often begin as minor movement faults.
Crushing, trapping, and shearing points
Closing edges, roller guides, hinges, tracks, and panel joints can create places where a person could be trapped or injured. BS EN 12604 addresses suitable clearances, guarding, and protection around these danger areas.
Powered entrances deserve extra attention because users may stand near the opening while the door moves. The HSE guidance on crushing zones around powered gates highlights how severe injuries can result where moving equipment meets a fixed surface.
Preventing uncontrolled falls
Vertically moving doors need protection against uncontrolled descent. A failed spring, cable, lifting component, or drive-related fault must not allow a heavy curtain or door leaf to fall freely.
Anti-drop devices, safety brakes, secure end fixings, correctly tensioned springs, and sound guides all play a part. If an engineer finds damaged cables, corrosion, recurring misalignment, or poor balancing, treat it as a safety issue rather than a cosmetic defect. Targeted roller shutter safety upgrades can add or improve protection where an older installation falls short.
How BS EN 12604 Fits With Other Door Standards
Industrial door compliance rarely comes down to a single document. Different standards cover mechanical design, powered operation, testing, documentation, installation, and ongoing use.
BS EN 12604 and BS EN 12453
BS EN 12604 deals with mechanical aspects. BS EN 12453 addresses safety in use for powered doors, gates, and barriers. If a roller shutter has a motor, remote control, push button, photoelectric sensor, safety edge, or hold-to-run control, both areas are relevant.
The HSE explains the relationship in its revision notice for powered-door standards. The 2017 revisions reorganised requirements previously spread across several door standards, including BS EN 12453, BS EN 12445, BS EN 12604, and BS EN 12605.
EN 13241 and installation paperwork
EN 13241 is the product-standard framework for industrial, commercial, and garage doors and gates. BS EN 12604 supports that framework by setting out mechanical safety requirements and test methods.
Installation and handover records should identify the door, its controls, operating instructions, safety features, limits of use, and maintenance needs. BS EN 12635 is also relevant to installation, handover, operation, maintenance, and repair.
A supplier’s declaration or original paperwork is useful, but it doesn’t prove the door remains safe years later. Later alterations, impact damage, unsuitable repairs, and poor maintenance can all change the risk.
What Industrial Door Owners Should Do
Owners do not need to become standards specialists. However, they do need a sensible system for checking doors, responding to defects, and keeping evidence of what has been done.
Inspect the whole door, not only the motor
Walk around the opening while the door is isolated and safe to inspect. Look for damaged laths or panels, loose bolts, bent guides, damaged seals, frayed cables, oil leaks, corrosion, worn hinges, and poor alignment.
Then observe a normal operating cycle from a safe position. The door should travel smoothly, stop correctly, and not strike the floor, lintel, or guides. Do not bypass an interlock, safety edge, photocell, or stop control to keep production moving.
Use planned servicing and clear records
The right servicing frequency depends on door type, traffic, exposure to weather, and operating cycles. A loading-bay shutter used throughout every shift needs closer attention than a small storeroom shutter opened once a day.
Keep a simple record of inspections, faults found, work completed, and the next planned visit. The PUWER roller shutter compliance guide explains why records help demonstrate that equipment is maintained and defects are acted on.
A professional service should include more than lubrication. Engineers should inspect the curtain or panels, guides, barrel, springs, cables, fixings, motor, controls, and safety devices, then test the door through full operating cycles.
Act quickly when safety is in doubt
Take a damaged door out of service if it drops, jams, runs unevenly, fails to stop, has exposed cables, or cannot secure the building. Keep people away from the opening until a competent engineer has assessed the fault.
For planned checks or fault diagnosis, industrial door and shutter servicing helps prevent small mechanical issues becoming disruptive breakdowns. If security or safe operation cannot wait, Contact Us to arrange professional assistance.
Common Misunderstandings About BS EN 12604
A standard is useful, but it cannot replace competent installation, risk assessment, or routine care. Several assumptions can leave owners with gaps in their safety arrangements.
“The standard is the law”
BS EN 12604 is a technical standard, not a complete statement of UK law. Workplace duties still require employers and duty holders to control risks, maintain work equipment, and use competent people for inspection and repair.
Using the standard can support good practice, but compliance needs to reflect the real site. A shutter beside a public pavement, a vehicle route, or a busy production line may need more protective measures than one in a locked plant room.
“The paperwork proves the door is safe”
Paperwork confirms what was supplied or recorded at a point in time. It cannot reveal a damaged guide, a fatigued spring, a loose fixing, or an inoperative safety edge that develops later.
The strongest evidence combines original documentation with current service reports, repair invoices, test results, and records showing that faults were dealt with promptly. This approach gives managers a clearer picture of the entrance’s present condition.
FAQ
Does BS EN 12604 apply to manual roller shutters?
It can. The standard includes manually operated vertically moving commercial doors, including roller shutters and rolling grilles used mainly for goods protection. Manual operation does not remove the risks linked to weight, balance, falling parts, sharp edges, or trapping points.
Is BS EN 12604 only relevant when buying a new door?
No. It is most useful during specification and installation, yet its mechanical principles also help owners assess older doors. Regular servicing can identify whether wear, damage, modifications, or missing protection have created new hazards.
Does a powered shutter need safety devices?
The required protections depend on the door design, controls, installation location, and foreseeable use. A powered door may need measures such as safety edges, photoelectric devices, suitable controls, guarded danger zones, and effective stopping arrangements.
How often should an industrial door be serviced?
There is no single interval that suits every door. Review its type, daily cycles, operating environment, age, exposure, and the people using the area. High-use shutters in warehouses, retail units, and loading bays often need more frequent checks than low-use doors.
Keeping Industrial Doors Safe in Daily Use
BS EN 12604 gives industrial door owners a practical way to understand mechanical risk. It focuses attention on stable movement, safe clearances, reliable support, and protection against uncontrolled falls.
A door’s security and convenience should never hide a developing safety fault. Planned checks, competent repairs, and accurate records keep the door reliable while helping protect people, stock, and day-to-day operations.
Commercial Door Measurements to Take Before Replacement
A replacement door can fail before it is fitted if the survey records only the brickwork width. Accurate commercial door measurements protect usable access, fire safety, security, and day-to-day operations.
A shutter, steel personnel door, fire exit, or automatic entrance needs space to open, close, lock, and allow people or goods through. Recording the full opening first helps prevent costly alterations once an order is placed.
Key Takeaways
- Measure the structural opening, finished opening, and clear passage width as separate figures.
- Take widths and heights in several locations because older openings can be out of square.
- Record headroom, side room, thresholds, wall construction, and fixed obstructions.
- Confirm how pedestrians, wheelchairs, trolleys, forklifts, and stock use the opening.
- Check fire escape, accessibility, security, and powered-operation requirements before selecting a replacement.
- A site visit is the safest basis for a specification. You can book a free site survey before committing to a door or shutter type.
Why Commercial Door Measurements Need More Than One Width
The visible opening is only the starting point. A replacement frame, door stops, hinges, seals, handles, shutter guides, and floor finishes can reduce the space people or equipment actually use.
A useful survey separates the dimensions needed to make the product fit from the dimensions needed to make the entrance work safely.
Structural opening versus finished opening
Measure the structural opening between the masonry, steelwork, or other permanent reveals. Take the width at the top, centre, and bottom, then record the smallest dimension. Do the same for height at the left, centre, and right.
Next, measure the finished opening. This includes any linings, cladding, wall protection, tiled reveals, or floor build-up already in place. A new threshold or resin floor can alter the finished height, so note planned works as well as existing conditions.
Clear opening is the usable passage
Clear opening width is the unobstructed passage when the leaf is open. It is often narrower than the nominal door size. A 1,000 mm door leaf does not automatically provide a 1,000 mm route once the frame, stops, and open leaf are considered.
For fire doorsets, the BWF fire-door measurement guidance measures clear width between the stop face and door-leaf face with the leaf at 90 degrees. For paired doors, measure from the leading edge of the secondary leaf.
Measure the Opening, Frame, and Door Arrangement
Start every survey with a repeatable record. A laser measure is useful for long dimensions, while a steel tape helps confirm local details such as reveals, thresholds, and frame depth.
Record width, height, depth, and squareness
Record the opening width and height in millimetres. Then measure reveal depth on both sides, lintel depth, and the available wall area around the opening. These figures affect frame choice, fixing method, architraves, shutter guides, and control equipment.
Check whether the sides are plumb and whether the head is level. A leaning jamb or sagging lintel can leave an apparently generous opening too tight for a square frame. Photograph cracks, loose blockwork, corrosion, or damaged steel before a replacement hides the problem.
Also note which side the door hangs from, its swing direction, and whether it opens inward or outward. A replacement that swings into a delivery path, corridor, or parked vehicle area creates a problem even when it fits perfectly.
Separate single leaves, pairs, and specialist doors
For a pair of doors, measure each leaf, the meeting stile, the inactive leaf arrangement, and the full opening when both leaves are released. Confirm whether staff use one leaf daily and open both only for deliveries or evacuation.
Roller shutters, sectional doors, high-speed doors, and steel hinged doors all use space differently. A sectional overhead door needs room for tracks and panels. A roller shutter needs a head box or barrel area, guides, and a suitable motor position.
When planning commercial roller shutter installations, provide the surveyor with details of the current product and the intended use. A warehouse loading opening needs a different solution from a shopfront that closes once each evening.
Record Clearance, Thresholds, and Nearby Obstructions
A door may fit within the opening but still clash with its surroundings. Measure the whole working area on both sides, including overhead services and traffic routes.
Check headroom and side room
Measure from the opening head to the lowest obstruction above it. Beams, lights, sprinkler pipework, cable trays, ducts, and signage can conflict with shutter boxes, sectional tracks, or automatic-door operators.
Measure side room on both sides too. Roller shutter guides, motors, safety edges, pull switches, key switches, and control boxes all need a safe position. A restricted side can dictate motor placement or require a different product layout.
For a roller shutter, record the full width between walls, the clear opening, the available headroom, and the space above the opening. Surveying only the opening width risks specifying a curtain that has nowhere to coil.
Assess floors and approach routes
Measure the threshold height from both sides and identify slopes, drainage channels, damaged concrete, raised tiles, or uneven finishes. A level transition is easier for pedestrians, wheeled stock, and mobility equipment. It also reduces the chance of a bottom seal dragging or catching.
Record the approach distance and turning space. Forklifts need more than a clear aperture. Their mast height, load width, approach angle, and turning route can all affect the required opening. Protective bollards may also be needed where repeated vehicle strikes have damaged guides or frames.
The smallest usable measurement controls the specification. A single low beam, proud threshold, or projecting guide can determine the replacement design.
Check Escape and Accessibility Before Ordering
A commercial entrance can have several duties at once. It may provide public access during the day, secure stock overnight, and form part of an escape route. The survey must identify which role applies.
Measure escape-route clear width
Where a door forms part of an escape route, record the clear width with the door open, not only the structural aperture. Approved Document B, Volume 2 states that clear width is measured at 1,500 mm above finished floor level where walls define the route.
Its guidance gives 750 mm for up to 60 people, 850 mm for up to 110 people, and 1,050 mm for up to 220 people. Larger occupancy figures use 5 mm per person above 220. Fire strategy, travel distance, alternative exits, and building layout all affect the final requirement.
Record panic hardware, closers, magnetic locks, access control, and any alarm interface. The inside escape operation must remain obvious and unrestricted.
Measure accessibility at the finished doorway
For a new non-dwelling building, Approved Document M guidance gives a clear width of 800 mm for a straight-on approach or a 1,500 mm access route. It gives 825 mm where the approach route is at least 1,200 mm wide, and 1,000 mm for external doors used by the public.
Existing buildings have different guidance, so avoid treating one figure as universal. Review the current Approved Document M access guidance alongside the particular building and planned work.
Measure the clear passage with any door leaf fully open. Include projections from handles, closers, shutter guides, access readers, radiators, furniture, and wall protection. Record the approach on both sides because a narrow corridor can affect the required clear width.
Survey Powered Doors and Security Shutters Properly
Power, controls, safety devices, and emergency operation are part of the measurement survey. They should not be added as an afterthought once a shutter or automatic door has been selected.
Map power and control positions
Record the available electrical supply, isolator position, cable route, and distance to the proposed motor or operator. Mark practical locations for push buttons, key switches, remote receivers, sensors, safety edges, and access-control devices.
Electric shutters suit openings with frequent pallet or vehicle movements because staff can operate them without manual lifting. For a security-led installation, a double-skinned steel curtain may offer a stronger option than a single-skin curtain. The right choice still depends on the opening, operating cycles, insulation needs, and risk level.
Businesses considering automation can compare appropriate electric roller shutter doors after the site dimensions and controls have been assessed.
Confirm emergency and safety functions
A rolling shutter serving a fire-related function needs a manual opening and closing arrangement for firefighting purposes. Record the manual override location and confirm that staff or emergency services can reach it safely.
Powered equipment also needs appropriate safety measures. The HSE identifies BS EN 12453:2017 and BS EN 12604:2017 as standards covering the safety of powered doors, gates, and barriers.
Measure sensor positions, closing zones, and the space where people could be trapped by a moving leaf or curtain. A control switch positioned behind a parked pallet or close to forklift traffic is not a safe operating arrangement.
Build a Survey Record That Installers Can Use
A clear survey record helps everyone work from the same facts. It should combine dimensions, photographs, product requirements, and conditions that may affect fitting.
Photograph the whole opening and its details
Take straight-on photographs of both faces of the opening, then photograph the head, jambs, threshold, hinges, locks, guides, motor, controls, and nearby services. Include images that show access routes, vehicle paths, and obstacles.
Label photographs within the project record rather than relying on memory later. Note the date, location, opening reference, and whether the image shows the internal or external face.
Add condition and maintenance findings
Record damaged slats, bent guides, corroded frames, failing motors, loose fixings, worn hinges, and poor door closure. Some faults may support repair rather than replacement, while others show that the opening itself needs work first.
After installation, regular inspections help preserve the dimensions and operation confirmed during the survey. Commercial roller shutter servicing can identify worn components before they cause a breakdown or leave premises insecure.
Frequently Asked Questions
Should I measure the old door or the opening?
Measure both, but prioritise the opening and usable passage. The old door may have been undersized, incorrectly fitted, or altered over time. Record the structural opening, finished opening, and clear width with the door open.
How much headroom does a roller shutter need?
It depends on the shutter type, curtain height, barrel size, hood, motor arrangement, and fixing method. Measure from the finished floor to the lowest overhead obstruction, then record the available space above and beside the opening for the supplier.
Can a replacement door reduce an escape route width?
It should not be selected on nominal size alone. The installed door, frame, stops, hardware, and open leaf position determine the clear width. Confirm the required escape width before ordering and check it again after fitting.
Get the Replacement Right at Survey Stage
The strongest commercial door measurements capture the full working opening, not a single width on a sketch. Clear passage, headroom, threshold levels, traffic patterns, and safety hardware all affect the final specification.
