BW C-PURLIN


BW C-PURLIN is a range of C shaped channels and girts manufactured from galvanized steel for structural and building construction applications. Our products are available either plain or with textured surfaces on the web. Pre-punched holes either round or elongated on the webs can be custom-drilled according to requirements. All our purlins are manufactured from high tensile steel for enhanced AL48 loading performance and durability while it remains lightweight.

BW C-PURLIN is offered with a zinc-coated protection surface and is engineered to be perfectly compatible with one another for box-up applications to deliver superior loading strength, stiffness and increased load capacity. Our products are produced in compliance with international standards to enable dimensional precision and consistent quality significant for cost economies in both design and installation.
