C purlins is made of galvanized steel strips by the method of cold-bending formed.The surface treatment is galvanized or bared. It has many advantages compared with traditional structural steel, such as light weight, excellent performance cross-section, high-strength and so on.
Z purlins is made of hot rolling steel sheet,and strictly under the cold roll formed by machine.,which is using as steel building purlins.Compare to the traditional box iron,Z section purlins can save 30%material wastage,and it has thin wall,light weight,good section performance and high strength features.Compare to C purlins,Z purlins are specially used for large slope roof.
