Double Egress Hollow Metal Door Frames

A door is considered an egress door when it forms part of a continuous, unobstructed path of exit travel from any point in a building to an exterior public way. Egress doors must meet strict building and fire codes, swinging freely in the direction of exit travel without requiring specialized knowledge, keys, or excessive effort to open during emergencies.

Hollow metal door frames are manufactured across standard and heavy-duty steel thicknesses ranging from 18 gauge to 12 gauge steel. Heavier 12 and 14 gauge options are recommended for high-impact corridor applications, whereas 16 and 18 gauge options suit standard commercial construction openings requiring dependable longevity.

Yes, double egress frames can be manufactured with official UL fire-rated labels in compliance with NAAMM and HMMA standards. These fire-rated assemblies help contain heat, smoke, and flames within designated corridor compartments, fulfilling essential commercial building code requirements for life-safety barrier protection.

Double egress frames are available in both fully welded and cut-and-notch knockdown configurations. Fully welded frames deliver maximum rigidity for heavy-traffic installations, while cut-and-notch assemblies provide convenience for transport and straightforward on-site assembly around existing wall conditions.

Frames are fabricated using durable metals including stainless steel and A60 galvannealed steel. A60 galvannealed coatings deliver superior corrosion resistance and paint adhesion for interior commercial spaces, while stainless steel alternatives offer outstanding protection against moisture and corrosive cleaning chemicals.

Hollow metal doors installed into egress openings can be built with multiple interior cores based on thermal and structural requirements. Core options include polystyrene, polyurethane, steel-stiffened assemblies, and temperature rise cores designed specifically to limit heat transfer during a fire.
