What's the Purlins?

Purlin 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.
C/Z-shaped purlins have excellent bending resistance and are easy to install.
They are widely used as roofs and walls in large and medium-sized buildings such as factories, warehouses, garages, exhibition centers, cinemas, theaters, gardens, etc.
