90 Minute Fire Rated Commercial Doors

A 90-minute fire rating identifies the tested fire-resistance duration assigned to the complete opening assembly under its applicable listing. It does not describe an unlimited period of protection or apply independently of the frame and hardware. For commercial projects, confirm that the selected door and frame combination carries the required UL label and matches the specified opening conditions.

Custom Metal Products offers UL-labeled fire-rated hollow metal doors and frames. Product information identifies UL fire-rated options and NAAMM/HMMA compliance. The required rating, configuration, core, frame profile, and hardware preparation should be reviewed for each opening so the selected assembly aligns with the project’s fire-rated and egress requirements.

Listed core options include polystyrene, polyurethane, temperature rise, and steel-stiffened constructions. The suitable core depends on the required fire-rated assembly, project specification, and performance considerations. Custom Metal Products can help review the opening requirements and identify an available configuration, including temperature rise core doors where specified.

Customisation options include flush and embossed panel designs, multiple gauge choices, standard and custom frame profiles, and assemblies incorporating sidelites, transoms, or windows. Double egress frames and oversized doors are also identified in the product information. Availability should be confirmed against the required UL-labeled assembly and project specifications.

Yes. The product range includes UL fire-rated hollow metal doors and frames, along with standard and custom frame profiles. Available configurations include double egress frames, sidelites, transoms, and window assemblies. Frame selection should be coordinated with the door, hardware, glazing or panel requirements, and the project’s fire-rated opening specification.

Applications identified for the range include commercial building construction, commercial fire-safety egress, double egress openings, hospitals and healthcare facilities, sidelites, transoms, and lead-lined frame applications. Some products are also identified for LEED-compliant construction. Final selection should reflect the building use, opening schedule, fire-rating requirements, and any specialised shielding needs.
