Door Frame Machine

A door frame roll forming machine produces the metal door frame profiles that encase and secure door panels in residential, commercial, and institutional buildings. These machines form L-shaped, U-shaped, and custom rebated frame sections from galvanized steel strip, producing frames that replace traditional timber door frames with fire-rated, corrosion-resistant, and dimensionally consistent metal alternatives. The profiles cover knock-down and welded frame types for both retrofit and new-construction installation methods.

Core advantages:

• L-shaped, U-shaped, and rebated frame profiles for metal door systems

• Material: 0.4–1.2mm galvanized steel strip

• Inline punching for hinge recesses, lock holes, and fixing points

• Forming speed 15–25 m/min with servo-driven flying cutoff

• Knock-down and one-piece frame configurations from interchangeable rollers

FAQ: What is a knock-down metal door frame? — Knock-down frames (KD frames) ship as three separate pieces—two legs and one header—that assemble on-site around the door opening, ideal for retrofit installations; one-piece welded frames arrive pre-assembled for new-construction embedment.
