Industrial door installation should be scheduled in two phases: specification during the design stage, and physical installation after the structural shell is complete but before interior finishing begins. For fire-rated industrial doors specifically, the sequencing matters because incorrect timing creates costly rework, delays to the critical path, and documentation gaps that can stall a building permit or fire safety inspection. The sections below address each scheduling decision an architect or project manager needs to make, from lead time planning to final commissioning.
What affects the lead time for industrial door installation?
Lead time for industrial door installation depends primarily on whether the door is a standard product or a custom-made unit. Standard fire-rated doors in common dimensions may be available within a few weeks, while custom industrial doors built to project-specific dimensions, fire resistance classifications, or automation requirements typically require longer production lead times that must be factored into the construction programme from the outset.
Several variables drive lead time beyond the basic production schedule:
- Opening dimensions: Large or atypical openings in production halls, logistics centres, or healthcare complexes fall outside standard product ranges. A manufacturer with in-house R&D and a dedicated production facility can accommodate these, but the design and engineering phase adds time before production even begins.
- Fire resistance classification: Doors specified to EI1 60, EI2 90, or EW classifications each involve specific tested configurations. Changing the classification late in the design process effectively restarts the production order.
- Automation and integration: Doors with magnetic hold-open devices, automatic closing on alarm, or integration with building management systems require additional configuration and testing before delivery.
- Documentation requirements: CE declarations, classification reports, and EPDs must accompany the product. If these are requested after order placement rather than at the specification stage, they can delay final acceptance.
For new-build industrial construction, a realistic planning assumption is that fire-rated industrial doors should be ordered no later than the moment the structural frame is confirmed, not when the finishing trades begin mobilising. Treating door procurement as a late-stage activity is one of the most common causes of programme delay in industrial projects.
When in the construction timeline should industrial doors be specified?
Industrial doors should be specified at the design development stage, before the contractor tender is issued. For fire-rated doors in particular, specification must include the required fire resistance classification — expressed per EN 13501-2 as E, EW, EI1, or EI2 combined with a duration in minutes — along with opening dimensions and any automation requirements, so that these constraints are priced and programmed from the start, not negotiated as variations during construction.
Specifying too late creates a chain of problems. If the fire door classification is left open in the tender documents, contractors may price a lower-performing product and then face a substitution request during the permit review. If dimensions are not confirmed before the structural opening is formed, remedial work to the surrounding structure becomes necessary. Both outcomes add cost and delay.
Architects working on industrial construction should approach door specification the same way they approach structural steelwork or facade systems: as a long-lead item that shapes the programme, not a fitting that can be selected from a catalogue at the end of the project. This means confirming the fire compartmentation strategy, identifying which openings require fire-rated doors, and selecting a manufacturer capable of supplying full technical documentation — including CE declarations, Efectis classification reports, and EPDs — before the design is frozen.
The appropriate fire resistance classification for a specific opening depends on the project’s fire safety calculation, not on a general rule. The BBL (Besluit Bouwwerken Leefomgeving) sets the absolute minimum requirement; a heavier classification may be required depending on the compartmentalisation calculation, sector-specific regulation such as PGS15 for chemical storage, a client’s above-statutory requirement, or an insurer’s requirement. For projects where the classification requirements are not straightforward, consult a qualified fire safety engineer or contact Metacon-Next directly.
For projects where BREEAM or LEED certification is a client requirement, EPD availability becomes a specification criterion in its own right. Manufacturers who publish EPDs alongside their technical documentation allow architects to close the environmental documentation file without chasing suppliers post-order.
How do you coordinate door installation with other construction trades?
Industrial door installation must be coordinated with the structural, masonry, electrical, and fire detection trades. The door itself cannot be installed until the structural opening is complete and dimensionally verified. Automation, alarm integration, and hold-open devices require electrical first-fix work before the door frame is fitted, and fire detection cabling must be in place before the automatic closing mechanism can be commissioned.
A practical coordination sequence for fire-rated industrial doors in a new-build project looks like this:
- Structural opening formed and verified: Dimensions must match the specified door unit. Any deviation requires either a structural adjustment or a revised door order.
- Electrical first-fix complete: Conduits and cable routes for automation, alarm integration, and hold-open devices must be in place before frame installation.
- Door frame and leaf installed: Carried out by a certified installer from the dealer network. Frame alignment and anchoring must follow the manufacturer’s installation instructions precisely to preserve the fire resistance classification.
- Electrical second-fix and integration testing: Automation controls, alarm triggers, and hold-open release mechanisms are connected and tested.
- Finishing trades: Wall finishing, floor finishes, and sealing around the frame are completed after the door is installed, not before.
A common coordination failure is the reverse: finishing trades complete the wall surfaces before the door frame is installed, which then requires remedial work to achieve the required fire-resistant sealing around the frame. This is particularly problematic in production halls and logistics centres where the wall construction is heavy and remedial access is difficult.
The project manager or lead architect should include door installation hold points in the construction programme, with sign-off required from the installer before finishing trades are permitted to proceed around each opening.
What documentation is needed before industrial doors can be installed?
Before a fire-rated industrial door can be installed, the following documentation must be available: the CE declaration of performance, the classification report from the independent test body, the manufacturer’s installation instructions, and confirmation that the structural opening dimensions match the tested door configuration. Installation without this documentation creates a compliance gap that can invalidate the fire resistance classification.
Each document serves a specific function in the compliance chain:
- CE declaration of performance: Confirms the product meets the requirements of the Construction Products Regulation (CPR) and states the declared fire resistance classification per EN 13501-2. For industrial fire doors, two CE-relevant standards apply simultaneously: EN 16034 (fire- and smoke-resisting closing element) and EN 13241 (industrial door, general). Both must be covered.
- Classification report: The independent test report, typically issued by Efectis, that substantiates the declared classification per EN 13501-2. Fire resistance testing follows EN 1634-1; smoke control testing follows EN 1634-3. Extended application rules are covered under EN 15269. This is the document a fire safety inspector or building control officer will ask to see.
- Installation instructions: Specify the exact conditions under which the tested performance is valid, including frame anchoring, clearances, and sealing requirements. Deviation from these instructions can void the classification.
- EPD (Environmental Product Declaration): Required on projects with BREEAM or LEED environmental credits. Should be requested at the specification stage, not after delivery.
Architects who specify certified fire-rated doors from manufacturers that publish full documentation publicly can verify compliance before the order is placed, rather than relying on post-delivery paperwork. This is a meaningful practical difference when working to a permit deadline.
Who is responsible for commissioning and inspecting fire-rated industrial doors?
Commissioning of fire-rated industrial doors is the responsibility of the certified installer, who must verify that the installed door performs in accordance with the manufacturer’s tested configuration. The building owner or occupier is responsible for ensuring that a periodic inspection and maintenance regime is in place after handover, as required to maintain the fire resistance classification over the service life of the door.
At project handover, the installer should provide a commissioning record confirming that the door has been installed in accordance with the manufacturer’s instructions and that all automation, alarm integration, and closing mechanisms have been tested and are functioning correctly. This record forms part of the building’s fire safety file.
Ongoing inspection is not optional. Fire-rated industrial doors in active use, particularly in production environments where forklift passage, dust, and mechanical wear are factors, require regular maintenance checks. The frequency depends on the intensity of use, but the maintenance requirements are set out in the manufacturer’s documentation and must be followed to keep the classification valid.
The question of who installs fire-rated doors is also a compliance question. Installation by unqualified parties, even if the product itself is correctly specified, can invalidate the warranty and the fire resistance classification. Metacon-Next supplies exclusively through a network of certified dealers and installers, which means both the product and the installation are covered. For architects specifying doors for projects in the Netherlands or internationally, confirming that installation will be carried out by a dealer within the certified network is part of closing the specification correctly.
If you are at the specification stage and need technical documentation, classification reports, or guidance on selecting the right fire resistance classification for a specific opening, contact Metacon-Next directly or request a quotation through the website. All certificates and EPDs are publicly available, so you can verify compliance before the order is placed. For questions about which classification a specific project requires, a qualified fire safety engineer or the local authority is the appropriate point of contact.
