Product Specification

Anti-Corrosion Hot Dip Galvanized Cold Formed C Channel Steel

Product Overview

Cold Formed Hot Dip Galvanized C Purlin, also known as C Channel Steel or C Section Purlin, is a lightweight structural steel component widely used in modern construction and industrial support systems. Manufactured from high-quality Q235 carbon steel coils through continuous cold forming technology, the product achieves accurate dimensions, consistent shape, and excellent structural performance without requiring traditional high-temperature hot rolling processes.

Compared with conventional hot rolled steel sections, cold formed C purlins feature a more optimized cross-sectional design with lower self-weight and efficient material utilization. The C-shaped profile provides strong bending resistance while reducing unnecessary steel consumption, making it an economical solution for large-scale construction projects where weight control, installation efficiency, and structural reliability are important.

Each C purlin undergoes a complete hot-dip galvanizing treatment, creating a durable zinc protective layer with a typical thickness of 60–120μm. The galvanized coating effectively protects the steel substrate from moisture, oxidation, salt spray, and industrial corrosion, making it suitable for outdoor and demanding environments such as photovoltaic power plants, coastal projects, chemical workshops, and agricultural structures.

Kejulixin provides customized C purlin solutions according to engineering drawings and project requirements. Dimensions including section height, flange width, thickness, length, and punching hole patterns can be adjusted for different installation systems.
