Commercial Exterior Steel Hollow Metal Doors

Exterior commercial applications require heavy-duty hollow metal steel doors built from A60 galvannealed or stainless steel to resist weathering. Doors featuring insulated polystyrene or polyurethane cores offer thermal efficiency, while 18ga to 12ga steel construction provides structural durability, security, and compatibility with commercial building hardware.

Commercial hollow metal doors are available in steel thicknesses ranging from 18 gauge to 12 gauge. Lighter 18-gauge options suit standard commercial construction, whereas 12-gauge models deliver maximum security, impact resistance, and durability for high-abuse exterior openings.

Exterior steel doors can be configured with multiple core materials depending on performance needs. Core options include insulated polystyrene and polyurethane for thermal barrier performance, steel-stiffened cores for increased structural rigidity, and temperature rise cores for fire-rated life safety openings.

Yes, hollow metal doors and frames can be manufactured with UL fire-rated labels and NAAMM/HMMA compliance. These assemblies meet commercial building life safety codes for fire egress applications, temperature rise requirements, and exterior exits where fire-rated compartmentalization is mandated.

Standard door fabrication lead times range from seven to ten business days. For urgent project deadlines or job-site door schedule corrections, quick-ship programs offer expedited fulfillment schedules ranging from same-day and one-day options up to five business days.
