U Shaped Steel Purlin Roll Forming Machine
The U shaped steel purlin roll forming machine is built for producing U-channel profiles used in fire-rated steel doors, fire shutter frames, light steel framing, drainage U-channels, and other structural components. With servo control and precision roller adjustment, the machine keeps channel opening tolerance within ±0.5 mm and can be configured for different sheet thicknesses and profile widths.
The forming machine can also be adapted for custom-section profiles used in automotive door frames, crane side plates, conveyor troughs, and other applications where formed metal parts require both strength and reduced weight.
