Stainless Steel Fire Rated Door Frames and Certification Documents

t470-41

A stainless steel fire rated door frame is a metal frame built to hold a fire door assembly for a set period of fire resistance. Approval depends on the frame, door, hardware and seals being tested and documented together, so the certification paperwork matters as much as the steel itself.

What a fire rated door frame is

A fire rated door frame is part of a complete door assembly designed to slow the spread of fire and smoke between spaces. Stainless steel is often chosen because it keeps its shape and strength at high temperatures better than many other materials, and it resists corrosion in stairwells, service rooms and damp areas.

The frame is not rated on its own. Its performance is tied to the door leaf, the glazing if any, the hinges, the locks, the intumescent seals and the wall it is fixed into.

Key points for building inspectors

When reviewing a project, confirm that the frame and door are listed together in the same test report or approval. A mismatch in thickness, profile or hardware is a common reason for rejection.

Check that the fire resistance period matches the drawings.
Confirm the frame material, gauge and finish are stated.
Verify that seals and hardware are part of the approved assembly.
Check that installation follows the tested fixing method.

Certification documents to request

Ask the supplier for a complete file before installation starts. Typical documents include the fire test report from an accredited laboratory, a declaration of conformity that references that report, drawings showing the exact configuration, and a material certificate for the stainless steel.

Make sure the documents name the same product and dimensions that will be delivered. Copies that refer to a different configuration do not prove compliance for your project.

How we work with contractors

Our process starts with an inquiry and photos, followed by an on-site measurement. We then prepare a drawing and a written specification for your approval before production begins at our factory on Rival Street in Tel Aviv.

Frames are cut, formed and assembled in the workshop, then finished and delivered for installation. Because we measure on site, the frame fits the opening as built rather than as drawn, which reduces delays on the job.

Installation and site checks

Fire rated frames must be fixed exactly as the tested assembly requires. Anchor type, spacing and the gap around the frame are all part of the approval, so installers should follow the supplier's written instructions.

Before closing the wall, check that the frame is square, plumb and firmly fixed, and that the seals and gaps are intact. Photograph the installation for your records.

Standards and when to ask the engineer

Requirements for railings and doors are set by Israeli standards and by the project's fire safety design. We refer generally to Israeli railing standard SI 1142 for guarding work, but exact dimensional and load values should always be confirmed with the project engineer.

If the fire resistance period, opening size or wall type is unusual, involve the fire safety consultant early so the assembly can be approved before fabrication.

Frequently asked questions

Can a fire rated frame be approved without a test report?

Generally no. Authorities and inspectors usually expect a test report or approval that covers the complete door assembly. Ask for it before ordering.

Why does stainless steel matter for fire rated frames?

Stainless steel keeps its strength under heat and resists corrosion well, which suits stairwells, service areas and damp spaces. The final rating still depends on the full tested assembly.

Do I need to send the drawings for approval?

Yes. We prepare a drawing and written specification that you approve before production, so the frame matches the opening and the approved configuration.

Who checks the installation?

The project inspector and fire safety consultant confirm the installation against the approved drawings and test documentation. We can provide the installation guidance and photos to support that check.

Common mistakes to avoid

Ordering a frame that is not part of the same tested assembly as the door, or accepting paperwork that describes a different size or hardware, are the most common costly errors. Always match the documents to the exact product delivered.

Our recommendation

Send us the fire rating, opening size and wall type at the start, and ask for the certification file to be reviewed alongside the drawings before production begins. This prevents rework and delays at the inspection stage.

Summary

A stainless steel fire rated door frame must be approved as part of a complete tested assembly, so verify the certification documents against the exact product before installation.
