The purlin bending machine is used to form straight metal strip or prepared purlin sections through controlled bending rather than a continuous roll-forming path. Matched upper and lower tooling applies force at the required bend line so the web, flange, or lip can be produced to the drawing while the workpiece remains supported. This approach helps workshops handle short runs, special sections, repair work, or profile changes that do not justify a dedicated roller set. The machine solves the problem of repeatedly bending long sections by hand or moving them between separate stations. Its main advantages are flexible tooling, direct angle control, compact processing, and practical changeover. Profile size, thickness, bend angle, tooling, working width, and handling supports can be customized.

Main Applications
The purlin bending machine is used for C-purlins, Z-purlins, edge returns, flanges, and project-specific structural profiles.
Short-batch jobs where a dedicated roll-forming setup would take longer than the actual bending work.
Workshop correction, sample preparation, or special sections that need controlled bends from an approved drawing.
Steel-structure fabrication where purlin dimensions, bend positions, and material thickness vary between orders.
FAQ
Q: Can the machine bend every purlin with one tool set?
A: No. Tooling should match the section geometry, material thickness, bend angle, and required inside radius before production starts.
Q: What profile information should be confirmed before manufacture?
A: Confirm the section drawing, material grade, thickness, overall length, bend positions, target angles, and expected production quantity.
Q: Can the equipment be customized for existing purlin production?
A: Yes. The purlin bending machine can be matched to the required profile family, available floor space, work-support method, and upstream or downstream handling arrangement.
