C-shaped steel by the hot coil cold-formed processing, thin wall light weight, excellent cross-section performance, high strength, compared with the traditional channel, the same strength can save 30% of the material.

C-type steel purlins according to the height of different divided into 80,100,120,140,160,180,200,250 and other specifications, the length can be determined according to the design, but taking into account the conditions of transport and installation, the length is generally not more than 12 meters.
