Commercial Hollow Metal Door Frames

Commercial hollow metal door frames are commonly available in steel thicknesses ranging from 16 gauge to 12 gauge. The choice of gauge depends on application durability, security demands, and traffic volume. Thicker 12-gauge frames are often specified for heavy-duty security or high-abuse environments, while 16-gauge options serve standard commercial interior and exterior applications.

Welded frames are fully assembled and joined at the corners at the factory, arriving on the job site ready for installation in masonry or drywall openings. Knock-down or cut-and-notch frames ship disassembled in separate jambs and heads, allowing for easier shipping, on-site handling, and wrap-around installation over finished drywall partitions during interior fit-outs.

Yes, hollow metal door frames can be supplied with UL fire-rated labels in compliance with NAAMM and HMMA standards. Fire-rated frames are engineered for life-safety openings, double egress doorways, and corridor partitions, helping contain fire and smoke within designated building compartments according to local commercial building codes.

Yes, commercial frame assemblies can be engineered to include transom frames, sidelite frames, and borrowed lights. These engineered openings accommodate glazed or paneled sections above or adjacent to the door opening, providing architectural versatility, daylight transmission, and visibility while maintaining required structural integrity and UL fire ratings.

Lead-lined hollow metal frames are specifically engineered for healthcare and industrial facilities requiring radiation shielding. Fitted with internal lead lining, these frames are installed in environments such as hospital X-ray rooms and CT scan suites to prevent radiation leakage around the perimeter of the protective door opening.

In addition to standard three-sided profiles, hollow metal frames can be manufactured in specialized configurations including pocket door frames, double egress frames, kerfed profiles, and arched or radius openings. Frames can also be configured with custom jamb depths to accommodate various commercial wall construction types and thicknesses.
