1. Equipment Overview

The C/Z purlin roll forming machine is a specialized cold roll forming device designed for manufacturing C-shaped and Z-shaped purlins used in the construction steel structure industry. In a single continuous pass, it processes metal raw materials—such as galvanized steel strips and color steel coils—into finished purlin products with high-precision cross-sections. The integrated production line includes continuous roll pressing, automatic punching, and fixed-length cutting.

2. Core Working Process & Technical Specifications

The core working process of this equipment follows a sequential flow:

Feeding → Leveling → Roll Forming → Punching → Fixed-Length Cutting → Finished Product Discharging

The machine features a flexible dual-die switching function, allowing quick conversion between C-shaped and Z-shaped purlin production without the need to replace the entire roller set.

The forming rollers are manufactured from Cr12MoV wear-resistant alloy steel, processed with precision machining and quenching treatment for extended service life.

Key Specifications:

• Material thickness range: 1.5mm – 3.0mm
• Forming speed: 8–12 meters per minute
• Applicable building span: 6–12 meters (ideal for steel structure workshops, warehouses, light steel villas, etc.)

3. Advantages & Applications

Characterized by high automation, precise forming accuracy, and easy operation, advanced intelligent models of this machine are equipped with a PLC control system and servo motors. These features enable digital parameter adjustment and real-time production monitoring.

The C/Z steel purlins produced by this machine offer the key benefits of light weight, high strength, and easy installation. Widely adopted by steel structure processing enterprises, this equipment has become indispensable in modern light steel structure building systems, effectively helping businesses reduce production costs while improving overall efficiency.
