Our purlin roll forming line is an advanced automated solution tailored for producing high-precision steel purlins—such as C-section and Z-section profiles—used as structural support elements in steel-framed buildings. This system is ideal for applications in industrial roofs, warehouse walls, commercial sheds, and prefabricated construction.
Our Sewer Treads are precision-engineered cold roll formed steel profiles designed for safe, non-slip access in underground sewer systems, drainage channels, and utility tunnels. Manufactured using our advanced roll forming equipment, these treads ensure high strength, corrosion resistance, and dimensional consistency—making them ideal for long-term use in harsh environments.
