Product Overview

Hot Dip Galvanized C Channel Purlin is a lightweight structural steel component widely used in modern construction systems, including photovoltaic mounting structures, industrial buildings, agricultural facilities, and steel framework projects. As a standard cold formed steel section, the C purlin is manufactured from high-quality Q235 carbon steel coils through continuous roll forming at room temperature, creating a precise C-shaped profile with excellent dimensional consistency.

Compared with traditional hot rolled steel sections, cold formed C purlins achieve optimized structural efficiency through a thinner wall design and improved section utilization. The C-shaped profile provides effective resistance against bending forces while reducing overall steel consumption, making it suitable for projects requiring lightweight structures, convenient installation, and reliable load support.

The product adopts a complete hot-dip galvanizing process, where the steel surface is coated with a durable zinc protective layer. With a typical zinc coating thickness of 60–120μm, the galvanized surface helps protect the steel from corrosion caused by rainwater, humidity, salt spray, and industrial environments. This makes the C purlin suitable for outdoor photovoltaic systems, coastal construction projects, chemical workshops, and other applications requiring long-term weather resistance.

Kejulixin supplies customized C channel purlins according to different engineering requirements. Section height, flange width, thickness, length, hole patterns, and surface treatment specifications can be adjusted based on customer drawings and project standards.
