C25019 C/Z Shape Galvanized Steel Purlins Girts AS/ANZ4600 Material for Residential Building

C/Z type steel is made of galvanized steel by cold bending, which has the characteristics of thin wall, light weight, good cross-sectional performance, and high strength. Compared with traditional channel steel, the same strength can save 30% of materials.

Our factory adopts advanced pre-punching technology, and the aperture and spacing of the holes are precisely drilled through a CNC production line in the factory, without the need for on-site drilling. This not only protects the galvanized layer of the purlins, but also avoids rust caused by on-site punching, extending the service life of the purlins. It also enables the purlins to be better connected to the boards, corner braces, and pull rod supports, making installation easier and with high accuracy.
