Application in light steel building system as purlins and girts,different specification and sizes are available.

Z section steel is made up of hot roll coil after cold bending process, with the great performance of light weight, light-gauge high strength and excellent section properties.  Compared to C section, smaller size will have the same machnical performance as bigger C sections, but Z section cost more time and human force in installtion. What is more, Z section steel can be applied to sloped rood with angle more than 1/4. Z section Z section steel has been widely applied to light building systems as girts and beams.
