Hollow Metal Door Frames and Jamb Details

Some hollow metal door frames are fire rated, but not every frame carries the same rating. Custom Metal Products offers UL-labeled fire-rated hollow metal doors and frames for commercial building fire safety and egress applications. The required assembly depends on the door, frame, hardware, glazing, wall assembly, and project specification, so the complete opening should be reviewed together.

Available gauge options vary by product and configuration. The product range includes frames from 12 gauge through 18 gauge, with several products offering 12 gauge through 16 gauge selections. The appropriate gauge can depend on the application, frame configuration, durability expectations, fire-rated requirements, and project specifications. Contact the team with the opening details for guidance.

Welded frames are assembled as a finished frame, while cut-and-notch, or KD, frames are supplied for job-site or shop assembly. Custom Metal Products offers both options across applicable frame configurations. The preferred assembly depends on installation planning, transportation, available shop capability, project sequencing, and whether the frame needs to be finished before delivery.

Yes. Hollow metal frame assemblies are available for sidelite, transom, and borrowed-light applications. Custom Metal Products offers engineered openings with glazed or paneled options, as well as standard and custom profiles. Project requirements should identify the opening layout, glazing or panel choice, fire-rating needs, and whether the assembly connects to a door frame or another opening condition.

Pocket door frames are available through the Pocket Door Frames & Trim Packages product line. These products support residential pocket door installation and commercial door frame systems, with standard and custom profiles, kerfed frames, and fully finished or cut-and-notch assembly options. Confirm the wall condition, door requirements, trim details, and assembly preference when requesting a quote.

Lead-lined frames are available for radiation-shielding applications in medical facilities, X-ray rooms, CT scan installations, and industrial facilities with radiation hazards. These frames use lead-lined construction and can be supplied with standard or custom profiles. The required shielding details should be specified with the project drawings so the frame configuration aligns with the opening and shielding requirements.
