Features and Usage

The C purlin forming machine is mounted with intensively processed rollers that are made of forged quality structural steel. The hard chromium coating on the surface makes the rollers with long service life.
This equipment is computer controlled on length setting, punching and counting.
In the front part, the machine adopts many flattening rollers for improving the flatness of the strip steel. After flattening, the purlin is smooth and flat enough to meet the standards. Moreover, the C purlin forming machine gets more economic benefit.
The C purlin formed by this machine is characterized by excellent bending resistance and easy installation.
The product made by our machine commonly works as the supporter of the roof and the wall of large scale and midscale construction including the factory, warehouse, garage, gymnasium, exhibition center, cinema, theatre, garden, etc.
