Product Description

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.

We manufacture a complete range of structural C and Z purlins and girts for industrial buildings, garages, verandahs, and carports, in fact anywhere that strong, reliable steel framing is required. Manufactured from quality galvanised steel, this is a fully integrated system allowing for flexible design options.

Supplied plain or punched, galvanised purlins are manufactured from high tensile steel for increased strength, reduced weight, and a long serviceable life.
