Galvanized C Purlin for Metal Warehouse

C-shaped steel is automatically processed and formed by C-shaped steel forming machines. C-shaped steel forming machines can automatically complete the C-shaped steel forming process according to the given C-shaped steel size.
 
C-shaped steel is widely used in purlins and wall beams of steel structure buildings, and can also be combined into lightweight roof trusses, brackets and other building components. In addition, it can also be used for columns, beams and arms in mechanical light industry manufacturing.
