Steel purlin

Purlins are used to connect roof beams and pillars as support for roof panels and wall panels in steel structure buildings. There are two common types: C beam and Z beam. They have the characteristics of reasonable structure, clear stress, convenient construction, and small amount of steel.

C beam: It is formed by cold bending and rolling of galvanized steel sheet. The cross-section resembles the English letter C, the thickness is 1.5-3.0mm, and the cross-section height is 75-250mm. It can be drilled, primed, electroplated, hot-dip galvanized, etc.


Z beam: It is formed by cold-bending and rolling of galvanized steel sheet. The cross-section resembles the English letter Z, with a width of 100-300mm and a thickness of 1.5-3mm. Z beam is specially designed for the characteristics of roof stress. When the slope is large, the force of the Z beam is better than that of the C beam, and it is not much different for the wall surface, but the Z beam is optimized for continuous overlap and no gap.
