The finished C shape does not appear at one station. Flat strip enters the guide, then each roll makes only part of the bend. On the Purlin Roll Forming Machine, the order of those bends follows the section drawing. The difference across the supplied range is substantial: C80 is 80x40x15mm, while C300 is 300x80x20mm. Hole requirements vary too. C80 is listed with no hole, C100 with 40mm, and C120-C300 as adjustable. Those details should be decided before the roller layout is finalized, especially if punching and cut-off will sit in the same line. Feed position, roll spacing and the hand-off to the cutter all depend on the profile that actually has to leave the machine.

Components
• Entry guide for strip position before the first roll.
• Roll stands and shafts, each making one part of the section.
• Frame, transmission and adjustment points keeping the roll path aligned.
• Exit support carrying the finished section toward the next operation.
Product Advantages
Progressive bending spreads the shape change across several stations and makes adjustment easier.
The Purlin Roll Forming Machine can be prepared from a confirmed profile drawing rather than a nominal size alone.
Ten listed sections give buyers a concrete production range to compare.
Forming and cut-off can be laid out together when workshop length is limited.
Main Applications
• C-purlins for roof frames, wall girts, sheds and warehouses.
• Workshops moving from intermittent bending to continuous section forming.
• Production covering several sizes in the listed C80-C300 range.
• Lines combining forming with punching, cut-off or receiving equipment.
FAQ
Q: Can this Purlin Roll Forming Machine make adjustable profiles?
A: No. It lists ten C sizes from C80 through C300 with different h, b and c dimensions.
Q: Are hole dimensions the same?
A: No. C80 has no hole, C100 lists 40mm, and C120-C300 are marked adjustable.
Q: What should be confirmed before roll preparation?
A: The section drawing, material thickness, hole requirement and downstream cutting method.
