High Rigidity Inner Rolled Edge C Channel Steel Profile For Agricultural Greenhouse & Partition Frame

Product Overview

Hot dip galvanized C purlin is a lightweight cold formed steel profile widely used in solar mounting systems, steel structure buildings, warehouses, and agricultural construction projects. It is manufactured from Q235 carbon steel coil through continuous cold roll forming, creating a precise C-shaped section with high bending strength and stable dimensional accuracy.

Compared with traditional hot rolled steel, cold formed C purlin features a lighter structure, optimized material utilization, and easy installation. The C-shaped design provides excellent load-bearing performance while reducing overall structural weight.

The surface is treated with hot-dip galvanization, forming a protective zinc coating of 60–120μm. This coating improves resistance to rust, moisture, salt spray, and outdoor corrosion, making it suitable for long-term service in photovoltaic farms, coastal areas, industrial workshops, and other demanding environments.

Customized solutions are available, including pre-punched holes, section dimensions, thickness, flange width, and length according to project drawings and installation requirements.
