Z-SHAPED PURLIN

Purlin is a horizontal beam or bar used for structural support in buildings, most commonly in a roof. Purlin is supporter to the roof or attic floor. Purlin is manufactured from high tensile galvanized steel such as HRC steel, CRC steel or HDG steel.

– Advantages:

+ Easily installating, creating pre-punched holes based on detail design, or making adjustment to meet the inquiries as we can do.

+ Cross-section excellent performance, high strength and impact resistance. 

+ Z-shaped purlin is extremely versatile and lightweight properties which make them easily adapted for use in a variety of different sized buildings. 

– Applications:

+ Civil Constructions: steel structure, and support system for roof, wall, etc.

+ For the metal buildings installed with concealed fixing or klip lok roof panels, metal building with bigger roofing loading capacitiy. 

+ Automobile manufacturing, transmission tower, ship bridges, road and railway construction, equipment room container, mineral bracket, etc. 

Vina One not only manufactures the products as our standard commercial specifications, but also make to customer’s orders.

Notes: We are able to manufacture the galvanized purlins in the zinc coating thickness of Z60 to Z275.

Full thickness is 1-3 mm.
