About Us
SBR Probuild manufactures high-strength C Purlins designed for secondary framing in PEB structures. Made from galvanized steel with 245–345 MPA yield strength, our purlins ensure structural stability, accurate dimensions, and corrosion resistance. Ideal for industrial sheds and warehouses, they support roof and wall cladding with fast, efficient installation.
Cold-formed C Purlins deliver excellent load carrying capacity while reducing structural dead load and overall steel consumption.
Manufactured with 120–275 GSM zinc coating to ensure superior corrosion resistance in industrial and coastal environments.
Factory pre-punched holes improve alignment accuracy, reduce site drilling time, and speed up bolting during erection.
Available from 80 mm to 250 mm depth with thickness options between 1.5 mm and 3.0 mm.
Produced using 245 MPA and 345 MPA yield strength steel for enhanced structural stability and durability.
Optimized section design reduces material usage, transportation weight, and installation time without compromising structural performance.
Purlins are generally available from 100 to 300 mm depth/height and 45 to 75 mm wide in several thickness with downturn lips (flanges)

Our C Purlins are manufactured from high tensile galvanized steel (245–345 MPA), ensuring superior load carrying capacity for roof and wall systems in PEB structures. Each section is roll-formed with dimensional accuracy to maintain structural alignment and long-term stability.

With 120–275 GSM zinc coating, our purlins provide strong protection against rust, moisture exposure, and industrial atmosphere. This makes them suitable for warehouses, manufacturing plants, and coastal projects across India.

Produced on advanced roll-forming lines, every C section maintains uniform thickness, straightness, and flange geometry. Strict quality checks ensure accurate punching, smooth edges, and ready-to-install sections delivered to your site.

We supply lightweight yet high-performance C Purlins designed to support roofing sheets, cladding panels, and structural loads efficiently.
