– Advantages:
+ C-shaped purlins are manufactured from pre-galvanised steel strip after rolling. It is easy for installating, or creating punching holes as demands.
+ C-shaped purlin has thin wall, light weight, cross-section excellent performance, high strength and impact resistance.
– Applications:
+ With high impact resistance, C purlin is used for structural support in buildings, most commonly in a roof.
+ Construction industry: Framed buildings, cladding and walling, and flooring support system.
Vina One not only manufactures the products as our standard commercial specifications, but also make to customer’s orders.
