Our C purlin roll forming machine is a fully automatic, heavy-duty cold roll forming unit specially designed for mass production of high-precision C-shaped steel purlins, a key load-bearing and structural component widely used in steel structure buildings. Also known as C channel steel machine, this equipment integrates automatic coil uncoiling, precision leveling, roll forming, synchronous punching, fixed-length flying shear cutting and automatic stacking into one seamless production workflow. It is the core production equipment for steel structure workshops, warehouses, commercial buildings, residential construction and prefabricated housing projects, providing a cost-effective, stable and efficient production solution for global building material manufacturers and steel structure enterprises.

主な利点と主な機能

Fully Automatic Production, Ultra-High Efficiency

This machine is equipped with a PLC intelligent touch screen control system, hydraulic automatic uncoiler and high-precision servo feeding system, realizing fully unmanned continuous production with a stable working speed of 8-25m/min, supporting 24-hour uninterrupted batch operation. The built-in flying shear cutting function enables fixed-length cutting without stopping the production line, which greatly improves production efficiency compared with traditional static cutting. Operators only need to set production length, quantity and punching parameters with one click, reducing manual labor input by over 60% and effectively shortening order delivery cycles for large-scale production demands.

High-Precision Forming, Stable Product Quality

Driven by imported servo motors and high-precision positioning encoders, the machine controls product size tolerance within ±0.5mm, ensuring every finished C purlin has uniform dimensions, straight edges and consistent flange width. The multi-stage forming rollers are professionally designed and calibrated, made of high-grade 45# carbon steel with precision grinding and hard chrome plating, featuring excellent wear resistance and long service life. Finished C purlins have smooth surfaces, no burrs, warping or deformation, with stable structural strength that fully complies with international steel structure building standards and ensures easy on-site installation and splicing.

Heavy-Duty Stable Frame, Long Service Life

Built for long-term industrial use, the main frame adopts thickened high-strength welded steel plate with overall annealing treatment, featuring high rigidity, excellent shock resistance and zero deformation even under continuous high-load operation. The transmission system uses high-quality gearbox and durable chain drive, running smoothly with low noise and minimal wear. Key electrical components adopt international premium brands such as Siemens and Schneider, guaranteeing stable and reliable operation, low failure rate and reduced downtime and maintenance costs for enterprises.

Wide Specification & Material Compatibility

This machine supports production of conventional C purlin specifications ranging from C80 to C300, with adjustable width and height via simple parameter setting, covering all mainstream sizes for global construction projects. It is highly adaptable to various metal coil materials, including hot-dip galvanized steel, galvanized steel, aluminum-zinc coated steel and cold-rolled steel, with a material thickness range of 1.2mm-4.0mm, meeting diverse raw material and load-bearing needs of different customers. It realizes one machine for multi-purpose use, avoiding repeated equipment investment and saving production costs.

Compact Structure & Space-Saving Design

Unlike bulky integrated production lines, this C purlin machine adopts a compact integrated frame design with a small footprint, making it suitable for small and medium-sized processing factories with limited workshop space as well as large-scale production bases. It is easy to install, commission and layout, with flexible site adaptability that helps enterprises make full use of workshop space and improve site utilization efficiency.

User-Friendly Operation & Low Maintenance

With an intuitive English touch screen interface, parameter setting and daily operation are simple and clear, and new operators can master full operation after short-term training, no professional technical background required. The system is equipped with fault self-diagnosis, emergency stop and automatic alarm functions, enabling quick troubleshooting and ensuring operational safety. Daily maintenance only requires regular lubrication and routine inspection, with simple steps and low long-term maintenance costs.
