To request technical drawings for a fire-rated door, contact the manufacturer or their certified dealer with your project specifications: the required fire resistance classification (such as EI1-60 or EI2-90), the opening dimensions, the wall construction type, and any operational requirements. With that information in hand, the manufacturer can generate the drawings you need for specification and permitting.
For architects working on industrial or commercial projects, technical drawings are not optional documentation — they are the basis for permit submissions, coordination with structural engineers, and demonstrating that a specified product actually fits the opening as designed. The sections below cover what those drawings contain, why classification affects which drawings apply, and how to approach the request at each project stage.
What information does a technical drawing for a fire-rated door include?
A technical drawing for a fire-rated door includes the overall dimensions of the door and frame, the required clearances and installation tolerances, the wall connection details, the position of hardware and operating components, and any special conditions tied to the fire resistance classification. For industrial doors, drawings also show the drive mechanism, guide rails, and the space required above and beside the opening.
More specifically, a complete drawing set for a certified fire door typically covers the following elements:
- Dimensional overview: clear opening width and height, frame depth, and panel or curtain thickness
- Wall connection detail: how the frame anchors to the surrounding construction, including minimum wall thickness and material requirements
- Lintel and head clearance: the space required above the opening for the door mechanism, particularly relevant for roller doors and overhead doors
- Hardware positions: location of hinges, locks, closers, hold-open devices, and electrical connections where applicable
- Classification-specific details: sealing systems, intumescent strips, and any construction features that are part of the tested configuration
For architects specifying products at the drawing stage, it is worth confirming that the drawings you receive correspond to the tested and certified configuration — not a generic product outline. A drawing that does not reflect the actual tested assembly creates risk during a fire safety review or building permit assessment. Manufacturers like Metacon-Next provide drawings that are directly tied to their certified product configurations, which means what you specify is what gets installed and inspected.
Why does the fire resistance classification affect which drawings you need?
The fire resistance classification determines the specific construction features a door must have to achieve that rating — and those features directly affect the drawings. Classifications are defined under EN 13501-2 and combine three criteria: E (integrity — flames and hot gases are stopped), W (radiation reduction — limits radiant heat transfer through the door, which is the Dutch standard baseline criterion), and I (insulation — limits temperature rise on the unexposed side). The number that follows indicates the minutes of guaranteed performance during a standardised fire test.
The distinction between EI1 and EI2 matters in practice. EI1 applies a stricter limit on temperature rise on the unexposed face; EI2 permits a higher temperature rise. A door classified EI1-60 and one classified EI2-60 carry the same fire resistance duration but differ on the insulation criterion. That difference may translate into a thicker door leaf, a different frame profile, or additional sealing around the perimeter — all of which appear in the technical drawings. An EW-classified door, such as EW 60, blocks flames and limits radiant heat transfer for 60 minutes but does not apply the insulation criterion at all.
This matters in practice because two doors that look identical on a floor plan may require very different installation conditions depending on their classification. For architects, this means you cannot use a generic drawing for a fire-rated door and apply it across multiple classifications. The drawing must match the classification stated in your specification. When you request a quotation or drawings from a manufacturer, always state the classification code in full — including whether the insulation criterion is EI1 or EI2, and the resistance duration in minutes. Which classification is required for a specific project depends on the fire safety calculation for that building; if you are uncertain, consult a qualified fire safety engineer or contact Metacon-Next directly.
What documents come with technical drawings for a certified fire door?
A certified fire door should come with a complete documentation package alongside the technical drawings. This package typically includes the CE declaration of performance, the classification report from the independent test body, installation instructions specific to the tested configuration, and — increasingly important for BREEAM and LEED-rated projects — an Environmental Product Declaration (EPD).
For industrial fire doors, CE marking is governed by two standards simultaneously: EN 16034, which covers fire- and smoke-resisting closing elements, and EN 13241, which applies to industrial doors generally. Both apply at the same time and are not interchangeable. The fire resistance and smoke control performance itself is classified per EN 13501-2, based on tests conducted under EN 1634-1 (fire resistance) and EN 1634-3 (smoke control), with extended application rules covered by EN 15269.
Each document in the package serves a distinct purpose in the specification and permitting process:
- CE declaration of performance: confirms the product meets the requirements of the applicable harmonised standards (EN 16034 and EN 13241) and states the declared performance for fire resistance, smoke control, and other relevant characteristics
- Classification report: the technical record of the fire resistance test, issued by an accredited test institute such as Efectis, specifying the exact conditions under which the classification was achieved and the limits within which results may be extrapolated per EN 15269
- Installation instructions: define the conditions under which the tested performance can be reproduced on site — wall type, anchor positions, frame preparation, and so on
- EPD: a standardised document quantifying the environmental impact of the product across its full lifecycle, based on ISO 14044 and EN 15804; relevant for projects seeking BREEAM or LEED credits and increasingly requested in European tenders
Architects should request this full package at the specification stage, not after the order is placed. If a manufacturer cannot supply classification reports and CE documentation before you commit to a product, that is a signal worth noting. Metacon-Next publishes its certified product documentation openly, including EPDs published in 2025 for most product lines, which allows architects to close a specification file without chasing paperwork later.
How do you request technical drawings for a custom-sized fire door?
To request technical drawings for a custom-sized fire-rated door, you need to provide the manufacturer with the exact clear opening dimensions, the wall construction details, the required fire resistance classification, and any operational requirements such as forklift passage, automatic operation, or hold-open functionality. The manufacturer then generates drawings based on the closest tested configuration that accommodates your dimensions.
Custom sizing in fire-rated industrial doors is common — logistics centres, production halls, and healthcare complexes regularly have openings that fall outside standard catalogue dimensions. The key point for architects is that a custom dimension does not automatically mean a custom test. Most certified manufacturers have tested their products across a range of sizes and can extrapolate to non-standard dimensions within the limits defined in their classification report under EN 15269. Those limits — maximum width, maximum height, maximum area — are stated in the report and must not be exceeded without additional testing.
When submitting a request for custom drawings, include the following:
- Clear opening width and height in millimetres
- Wall thickness and construction material (concrete, steel frame, masonry)
- Required fire resistance classification in full — stating the complete code, for example EI2-60 or EW-30, and always specifying EI1 or EI2 where insulation applies
- Operational mode: manual, motorised, automatic with smoke detector trigger
- Any special conditions: high traffic frequency, forklift passage height, hazardous environment
With this information, the manufacturer can confirm whether your dimensions fall within the tested range and produce drawings that reflect an installation you can actually specify and have installed. Through the Metacon-Next quotation request, architects and their teams can submit project parameters and receive product-specific technical documentation without extended back-and-forth.
At what project stage should you request fire door drawings?
You should request technical drawings for fire-rated doors at the preliminary design stage — before the structural drawings are finalised and certainly before the permit application is submitted. Fire door dimensions, frame depths, and required clearances affect the surrounding construction. Requesting drawings too late in the design process can result in conflicts with structural elements, insufficient lintel space, or wall thicknesses that do not meet the installation requirements of the tested configuration.
In practice, the timeline looks like this:
- Preliminary design: request indicative drawings and dimensional data to reserve the correct opening size and wall depth in the structural design
- Permit application: include the CE declaration and classification report in the fire safety documentation submitted with the permit; ensure both the EN 16034 and EN 13241 declarations are present for industrial fire doors
- Tender stage: provide the full technical specification — including the complete classification code (e.g. EI1-60 or EW-120), dimensions, and documentation requirements — so contractors can obtain accurate quotes from certified installers
- Construction phase: confirm that the installation drawings match the as-built wall construction before installation begins
Architects who wait until the tender phase to request drawings often discover that the opening they designed does not accommodate the required frame depth, or that the wall material specified is not compatible with the tested installation method. These are corrections that cost time and sometimes require structural revisions.
Metacon-Next supports early-stage specification through its dealer network and direct technical contact. Architects can reach the technical team to request drawings and documentation at any project stage, and the full product range — including fire-rated roller doors, overhead doors, and sliding doors — is available with complete technical documentation from the outset. For projects where the timeline matters, having a manufacturer who can supply drawings and certification documents without delay is part of closing a design file on schedule.
If you are working on a project that requires fire-rated industrial doors and want to confirm whether a specific product and dimension combination falls within a tested and certified configuration, the most direct step is to submit your project details and request the corresponding drawings. You can also learn more about Metacon-Next’s manufacturing and certification approach to assess whether the product range fits your specification requirements before making contact.
