Structural and Economic Advantages of Z PurlinsZ purlins are cold-formed steel profiles widely used in modern steel buildings due to their lightweight yet robust design. Their Z-shaped cross-section offers superior load-bearing efficiency compared to traditional hot-rolled purlins, reducing material

The structure of the roof truss: The structure of the roof truss mainly depends on the roofing materials used and the requirements of the house. Mainly triangular roof truss, triangular arch roof truss, shuttle roof truss, flat slope trapezoidal steel roof trussThere is not much difference in essenc

The material has high strength, and its own light weight steel has high strength and high elastic modulus. Compared with concrete and wood, the ratio of density to yield strength is relatively low, so under the same stress conditions, the steel structure has a small cross-section, light weight, easy

PE coating type:Instruction:PE coating is shorted for Polyester coating,which has good adhesion to materials, and make color coated steel sheets be easily processed and formed. Because of cheap price and wide range of color and gloss,this coating type is widely used in many products.The substrate co
