C Purlin Roll Forming Machines
This C purlin roll forming machine belongs to C/Z Purlin Roll Forming Machine series, which automatically manufactures C-shaped purlins for steel workshops, warehouses, greenhouses and photovoltaic supports. The finished C channels feature standard cross-section and strong bending resistance, being essential load-bearing profile processing equipment for steel structure projects. It can form a full automatic production line matched with uncoiler and slitter, widely popular among domestic and overseas steel structure & photovoltaic building material factories.
The machine base frame is integrally welded with thick H-beam steel and treated by high-temperature stress relief annealing to eliminate welding internal stress. The long frame runs vibration-free without deformation during long high-speed heavy-load production, guaranteeing straightness and dimensional precision of C purlins. All forming rollers are precisely machined from solid 45# carbon steel with quenched thick hard chrome plating, wear and rust resistant without scratching galvanized coating of galvanized & aluzinc coils. Multi-stage progressive roller stands form standard C-channel in one pass, and integrated on-line hydraulic punching stations punch mounting holes simultaneously to skip secondary processing and boost production efficiency greatly. It processes galvanized steel coils from 1.2mm to 3.0mm thick, adjustable purlin size range C80–C300mm without full roller replacement.
Equipped with high-power variable frequency main drive and heavy-duty synchronous chain transmission, the machine runs smoothly with strong load capacity, forming speed steplessly adjustable from 6 m/min to 15 m/min. Servo automatic deviation corrector at feeding inlet adjusts steel strip position in real time to avoid defective purlins. Servo hydraulic flying shear at the tail delivers clean burr-free cuts with dimensional tolerance controlled within ±0.5mm. The suspended cantilever PLC touch screen control system allows presetting purlin height, punching spacing, finished length and total output quantity. The machine automatically completes feeding, multi-pass roll forming, on-line punching, fixed-length cutting and counting without extra labor. Only one worker can realize 24-hour non-stop continuous production, cutting secondary processing labor cost significantly.
Every C purlin forming machine undergoes a 72-hour full-load coil test before delivery to calibrate forming section, punching positioning and cutting tolerance. A full set of spare forming rollers, punching dies, hydraulic sealing parts and bilingual operation manuals are supplied as standard accessories. Xinnuo offers a 2-year full machine warranty, electrical system voltage customization available for all countries. Overseas buyers get remote CNC debugging and on-site installation training by professional engineers. This high-precision fast-adjustable C channel machine gains consistent recognition from global steel structure manufacturers.
