About Us
Z Purlins from SBRProBuild are cold-formed galvanized steel members designed to deliver high load-bearing strength with reduced steel consumption. Manufactured in multiple depths and thicknesses, our Z sections improve span capacity, simplify installation, and reduce structural weight making them ideal for industrial sheds, warehouses, and PEB structures.
Cold-formed galvanized steel ensures superior structural efficiency, allowing longer spans while reducing overall dead load on primary framing systems.
Factory-punched holes (18x24 mm capsule, 14x24 mm round) enable accurate alignment, faster bolting, and reduced on-site fabrication time.
Available from 120 mm to 300 mm depths with flange variations, supporting diverse roof and wall load requirements.
Manufactured in YS 245 MPa and 345 MPa grades to match structural design calculations and project-specific load parameters.
Offered with 120 GSM, 175 GSM, and 275 GSM zinc coating to enhance corrosion resistance in industrial environments.
Supplied in 1.5 mm to 3.0 mm thickness options, allowing engineers to optimize purlin spacing and structural cost efficiency.
Purlins usually delivered with holes punched at any position on the web & flange as required, this facilitates supplied material to be ready to use on site arrival thus saves time. Capsule Punching dimension: 18mm X 24mm. Round Punching dimension: 14mm X 24mm

Our facility uses modern roll-forming machinery and strict quality control systems to maintain dimensional accuracy, coating consistency, and structural integrity in every batch.

Pre-engineered lengths with factory punching reduce site cutting, minimize erection errors, and speed up roofing and cladding installation timelines.

Our purlins are widely used in warehouses, power plants, high-rise sites, and industrial sheds across India, delivering dependable structural support.

We use premium-grade raw materials compliant with IS specifications, ensuring durability, cost efficiency, and long service life in demanding environments.
