Profile Information
C purlins are widely used for steel structure roofing and wall support. Their C-shaped design provides high strength, lightweight structure, and multiple size options for different buildings.
C purlins are commonly produced from 1.5-3.0mm galvanized steel or black steel coils because these materials provide strong load capacity, corrosion resistance, and stable structural performance.
How Does The Roll Forming Machine Work?
Machine Details
Steel Coil Decoiler
Steel coil decoiler is used to unwind metal coils smoothly for feeding into roll forming, cutting, or punching processes.
Manual decoiler is a basic and economical option, while motorized and hydraulic decoilers are also available for higher efficiency and automation:
| Power Type | Manual | Steel Coil Width | Max 1250mm |
| Loading Capacity | 5/7/10 Ton | Expanding Range | 460-50mm |
Roll Forming Machine
This chain-driven roll forming machine adopts a wall plate structure for stable and economical production of one fixed-size C purlin. Steel coils gradually pass through multiple forming stations to achieve the final profile shape.
Compared with gearbox structures, this standard configuration offers easier maintenance and lower investment cost.
We also provide customized solutions for multi-size production, punching systems, and higher automation requirements.
| Speed | 20m/min | Forming Station | 18 Stands |
| Motor Power | 7.5Kw | Shaft Diameter | 76mm, solid |
| Driving System | Chain | Roller Material | Gcr15,HRC58-62° |
| Frame Structure | Wall panel | Shaft Material | 40Cr heat treatment |
Hydraulic Cut
The hydraulic cutting unit adopts a stop-to-cut system, meaning roll forming pauses during cutting to prevent profile movement and ensure stable cutting accuracy. This solution is suitable for standard-speed production and clean profile ends. For customers requiring faster production speeds, customized flying cutting solutions are also available.
| Power Type | Hydraulic cut | When Cutting | Forming stops |
| Blade Material | Cr12MoV | Length Tolerance | ≤±1mm |
PLC Control Cabinet & Encoder
In a cold roll forming line, the encoder works with the PLC to provide real-time feedback on material position and speed, ensuring precise feed, synchronized forming, and accurate length control for cutting and punching.
Production speed, product length, and quantity can be set on the control cabinet. The display language can be customized according to customer requirements.
