Double Door Frames

A hollow metal double door is framed using either fully welded assemblies or cut-and-notch knock-down configurations. The frame consists of a head and two jambs engineered to anchor securely into surrounding commercial wall conditions. Depending on structural and life-safety specifications, assemblies may feature double egress jamb designs, transom integrations, or lead-lined shielding.

Double door frames are manufactured across a range of steel thicknesses to suit diverse commercial performance levels. Gauge options include 18-gauge, 16-gauge, and robust 12-gauge steel. Thicker gauges provide maximum durability for heavy commercial traffic, high-impact environments, and secure life-safety egress openings.

Yes, hollow metal double door frames are available with UL fire-rating certification and meet NAAMM and HMMA compliance standards. These fire-rated assemblies are engineered to fulfill strict commercial building life-safety codes, supporting paired doors and double egress fire door configurations where containment and reliable egress are mandatory.

Frames are available as fully welded units or cut-and-notch knock-down assemblies. Fully welded frames arrive pre-assembled for rigid installation into rough openings, while cut-and-notch frames offer flexible transport and field assembly, making them suitable for diverse commercial construction job sites and retrofits.

Yes, hollow metal frames can be manufactured for specialized requirements, including lead-lined configurations designed for radiation shielding in hospital and healthcare facilities. Custom configurations also include pocket door frames, sidelite and transom frame combinations, and custom arched, radius, or segmented profiles.

Hollow metal door frames typically carry standard lead times of five to seven business days. Select quick-ship programs and products can be delivered in as little as one day to several business days, supported by direct-to-job-site delivery via dedicated truck fleets in designated service areas.
