Hollow Metal Fire Door
UL 10C LISTED • IBC 2021 COMPLIANT
Hollow Metal Fire Door — SDI-Compliant Construction, UL-Certified Performance
Hollow metal fire doors represent the industry standard for commercial fire-rated openings. Bastion's Hollow Metal Fire Door combines a rigid steel shell with an engineered internal core — typically honeycomb, polystyrene, or mineral wool — to deliver an optimal strength-to-weight ratio. This construction method produces a door that is significantly lighter than solid steel alternatives while maintaining full UL-certified fire ratings up to 3 hours. The reduced weight simplifies installation, reduces hinge and frame stress, and lowers long-term maintenance costs without compromising safety.
