Commercial Steel Fire Exit Doors

Fire code requirements for exit doors dictate that egress pathways maintain fire-rated protection to prevent the spread of smoke, heat, and flames. Assemblies must feature certified UL fire ratings, approved latching hardware, and self-closing devices. Depending on building occupancy and wall construction, exit doors must satisfy designated hourly ratings and temperature rise limits to allow building occupants to evacuate safely during an emergency.

Commercial fire exit doors are available in heavy-duty steel thicknesses ranging from 18 gauge down to robust 12 gauge. The choice of gauge depends on anticipated usage frequency, environmental exposure, and security needs. Thicker gauges such as 14 or 12 gauge offer enhanced structural integrity and impact resistance, while 18 or 16 gauge is common for standard commercial interior egress openings.

Hollow metal fire exit doors are manufactured with several core configurations to meet thermal, acoustic, and life-safety specifications. Core options include temperature rise cores, steel-stiffened cores for maximum durability and strength, polystyrene cores, and polyurethane cores. Temperature rise cores are specifically designed for stairwells and exit corridors to minimize heat transfer to the unexposed face of the door.

Yes, custom metal frames are available to accommodate diverse commercial architectural openings. Available configurations include standard welded frames, double egress frames for bidirectional corridor traffic, transoms, sidelites, and custom profiles such as arched, radius, or segmented openings. Frames can be fabricated in matching steel gauges and material types, including A60 galvannealed and stainless steel.

Standard door lead times typically range from seven to ten business days, while standard frame lead times range from five to seven business days. For urgent job-site requirements, expedited quick-ship programs are available with lead times ranging from same-day to one-, two-, three-, or five-day manufacturing intervals for select door configurations and profiles.

Commercial steel doors and frames are supplied with a standard one-year warranty covering manufacturer craftsmanship and materials. This warranty ensures that the doors meet specified structural integrity, core bonding, and dimensional tolerances under standard operating conditions when installed and maintained in accordance with industry best practices and building code standards.
