Product Description

Product Introduction

What's C purlins?

C channel is made of galvanized steel strips by the method of cold-bending formed.The surface treatment is galvanized or bared. It has many advantages compared with traditional structural steel, such as light weight, excellent performance cross-section, high-strength and so on.

Product Advantage

☆Anti-Corrosion
The hot-dip galvanized coating provides a robust, long-lasting barrier against rust and corrosion for these C purlins. This superior protection ensures the structural integrity of your roof or shed frame is maintained, even in challenging environments. It significantly extends the service life of the building, reducing long-term maintenance needs and costs.

☆Earthquake Resistance
Their high-strength C-section design offers excellent load-bearing capacity and structural stability. This enables the steel purlins to effectively absorb and distribute seismic forces during an earthquake. By choosing these section frames, you enhance the overall safety and resilience of your construction against natural disasters.

☆Easy To Install
The pre-punched holes streamline the installation process for roof and shed purlins. This design allows for quick, precise assembly with standard tools, eliminating the need for on-site drilling. It saves significant labor time and cost, accelerating your entire building project timeline from framing to completion.

☆Recyclable
Made from 100% recyclable steel, these galvanized purlins are an environmentally responsible building material. At the end of their long service life, the C section frames can be fully recycled into new steel products. This supports sustainable construction practices and contributes to a circular economy, reducing the project's environmental footprint.

Product Application

It is used widely as purlin and wall beam on steel structure construction.Also it can be combined into a light weight roof truss,brackets,etc.In machinery light manufacturing,C purlin can also be made into Column,beam or arm limb,etc.
