C/Z Purlins are cold-formed thin steel members with C or Z cross-sections, widely used in steel structures.
C purlins, with symmetric sections, are easy to install, suitable for one-way load-bearing. Z purlins, featuring strong lap joints and high bending resistance, fit large spans. Both are lightweight, high-strength, and seismic-resistant, ideal for roofing and wall load systems in factories, warehouses, gyms, reducing building weight and enhancing stability.

Product Description

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.

Holes are made during production at continuous line,some additional notes are showing as follows:

· Holes can be made in a row or positions as per your design;

· Oval and rectangular holes can be rotated by 90°;

· Please contact us for additional information about the pre-punching possibilities,if you have any special hole punching requirement about hole size and hole shapes.

Production process:

1) Material preparation:Usually our steel material standards of Z purlin is Chinese standards Q195/235/345,we could also make as per your steel standards;
2)Hole pre-punched:If you have hole punching requirement,we could exactly punch the holes as per your requirements;
3)Cutting:Length could be any customized size,but it will be limited by container size,it's max 5.8meters for 20FT container and 11.8meters for 40FT container;
4)Quality inspection:We have QC people in workshop to do quality inspection,to ensure the product quality for customers.
