What Is a Hollow Metal Door?
A hollow metal door is a commercial steel door constructed with metal face sheets surrounding an internal core or reinforcement system. These doors are widely used in commercial, institutional, and multifamily buildings because of their durability, configurable hardware, and availability in fire-rated assemblies.
Capitol Fireproof Door manufactures custom hollow metal steel doors for projects throughout NYC and Long Island. Available configurations include flush doors, vision panels, louvers, and specialized hardware preparations, subject to applicable requirements.
