Purlin

Their primary function is to transfer loads from roof or wall panels to the main structure (such as beams or columns) and provide a secure mounting base for roofing or wall sheeting. Common purlin types include C-section, Z-section, and U-section, manufactured through cold roll forming, offering lightweight design, high strength, and easy installation.
Purlins can be customized in length, thickness, and cross-section dimensions according to project requirements, accommodating various spans and load conditions. Surface treatments such as hot-dip galvanizing or anti-corrosion coating extend service life. They are widely used in industrial plants, warehouses, garages, agricultural buildings, sports facilities, and commercial building roofing and wall structures. The efficient mechanical properties of purlins not only enhance structural stability but also reduce overall steel consumption, lowering construction costs.
