Product Details

The C Purlin Cold Roll Forming Machine is a high-precision industrial solution designed to extrude steel strips or plates into specialized C-shaped profiles. By utilizing a series of engineered rollers, the system progressively transforms raw metal coils into structural components ideal for construction, shelving, and industrial framing. This automated process integrates punching and stamping capabilities online, ensuring that every section is precisely formed and cut to exact specifications.

Engineered for mass production, our equipment employs high-grade D2 and D3 roller materials to withstand intense mechanical stress and ensure long-term durability. From the initial uncoiling and flattening process to the final hydraulic servo cutoff, the production line is optimized for stability, speed, and material efficiency. Whether you are producing C-purlins, Z-purlins, or hat profiles, this machine delivers consistent quality across multiple steel grades.
