| C-Purlins and Z-Purlins |
|
| |
C/Z-Purlins are roll formed from high-tensile Zinc Coated steel available in various sizes with base steel thickness of 1.60mm, 2.00mm, and 2.50mm.
They are suitable for roofing and wall cladding supports and for structural frames of buildings. Due to the lightweight and high strength of the steel and the Zinc-coated surface, C / Z Purlins are versatile and economical and require minimal maintenance throughout the life span of the building. |
