Light-gauge cold-formed steel roof purlins replace heavier hot-rolled steel angle and channel sections. A purlin is a secondary structural member that spans between the primary/main steel frame to support the roof cladding. The purlin transfers load from the roof cladding to the primary steel rafters. Similarly, a side rail is a secondary structural member that spans between the primary/main steel frame to support the wall cladding and transfer load from the wall cladding to the primary steel columns. Both purlins and side rails are used to provide restraint to the primary steel frame members. Light gauge cold-formed steel roof purlins are used on a wide range of building types including retail and leisure, industrial, warehouses and distribution, healthcare and education.
Purlin and wall beam of steel structure building.
The Z-shaped purlins have excellent anti-bending property and are easy to install. They are widely used as the supporter of roof and wall in large-scale and mid-scale construction, such as factory, warehouse, garage, exhibition center, cinema, theatre, garden and so on.
Z-channel steel is widely used in steel purloins, wall beams which can be combined into its own light weight roof trusses, brackets and other building components.
In addition, light manufacturing machine can be used in the columns, beams and arms and so on. Z channel is formed by pressing the high strength steel plate, so the specification and size is adjustable. After cold bending process, compressive strength is big; size of cross section is dexterous, so that it conforms to the purloin stressed characteristic to enable the steel products mechanics potency to be fully displayed. It is possible to reduce the roof weight of constructions and reduces the project to use the amount of steel.
