Process Introduction

C and Z channel is made of galvanized steel strips by the method of cold-bending

formed.The surface treatment are galvanized or bare. It has many advantages compared

with traditional structural steel, such as light weight, excellent

performance cross-section, high-strength and so on.

C/Z purlins are lightweight, cold-formed steel profiles crucial for modern steel structures. C-purlins (U-shaped with parallel flanges) offer high load-bearing capacity, ideal for roofs and walls requiring stiffness. Z-purlins (Z-shaped with angled flanges) provide excellent overlapability, reducing material waste in continuous spans. Both are corrosion-resistant, often galvanized, and cost-effective. They simplify installation, support cladding materials, and distribute loads efficiently, ensuring durability in industrial, commercial, and residential buildings. Choose C for stability or Z for flexibility—key components for robust, versatile steel frameworks.
