Commercial Hollow Metal Door Frame Sizes

Rough opening requirements vary by frame configuration, wall condition, and assembly method, such as fully welded or cut-and-notch knockdown frames. Because profiles and jamb depths differ across commercial construction designs, exact rough opening dimensions are determined by project submittals and engineering plans. Consult our estimating team for specific schedule requirements.

Commercial hollow metal door frames are manufactured in steel gauge thicknesses ranging from 18 gauge down to 12 gauge, with common options including 16 gauge and 12 gauge. Material options include A60 galvannealed and stainless steel, providing structural durability across standard commercial, high-traffic egress, and radiation-shielded healthcare wall openings.

Yes, frames are available with UL fire-rating labels and manufactured in compliance with NAAMM and HMMA standards. These fire-rated frames suit life-safety egress doorways, double egress configurations, transom assemblies, and glazed or paneled side lite openings designed to maintain building compartmentation and life-safety compliance.

Frames are available as fully welded units or as cut-and-notch knockdown assemblies. Knockdown frames facilitate straightforward transport and job-site assembly, while fully welded units arrive factory assembled for rigid perimeter placement in commercial, industrial, or medical wall constructions.

Yes, standard and custom frame profiles can be engineered to order. Custom capabilities include arched, radius, and segmented frame profiles, alongside engineered openings featuring side lites, transoms, borrowed lights, and lead-lined radiation shielding configurations designed to exact architectural specifications.

Standard frame manufacturing lead times range from five to seven business days. Expedited quick-ship programs are also available, including select lead times ranging down to same-day dispatch depending on order specifications, frame profile requirements, and production scheduling.
