C / Z Purlin Roll Forming Machine

Category: Roll Forming & Sheet Metal | Manufactured by Gagan Engineering Works, Khopoli, Maharashtra

The C / Z Purlin Roll Forming Machine manufactured by Gagan Engineering Works in Khopoli, Maharashtra is an advanced, high-yield continuous roll forming line engineered for manufacturing structural C-purlins and Z-purlins used extensively in Pre-Engineered Steel Buildings (PEB), solar mounting structures, warehouses, and industrial infrastructure. Built to process high-tensile galvanized steel and hot-rolled coils from 1.5 mm to 3.0 mm thickness, the machine features 16 to 20 progressive forming stations equipped with precision CNC-machined Cr12/EN31 vacuum heat-treated rollers (58–62 HRC) and solid 75 mm 40Cr alloy shafts. An innovative quick-change mechanical design allows operators to transition between C-section and Z-section profiles in under 30 minutes without disassembling roller sets, with web widths adjustable from 100 mm to 300 mm and flange heights from 40 mm to 80 mm. The line incorporates a multi-station hydraulic hole and slot punching unit for automated bolt-hole fabrication, followed by a hydraulic post-cut flying shear that produces clean, zero-distortion profile cut ends. Driven by a 25–30 HP heavy-duty motor through precision distribution gearboxes and orchestrated by a Delta/Siemens PLC touchscreen interface, the line delivers consistent forming speeds of 10 to 18 meters per minute with tight dimensional tolerances.
