C/Z/U Purlins

CZU Channel Steel Sections refer to a series of cold-formed thin-walled steel profiles, including C Purlins, Z Purlins, and U Purlins. They are typically manufactured from high-quality hot-dip steel such as galvanized steel, galvalume steel, or ZAM-coated steel strips through roll-forming. These sections are lightweight yet strong, which are highly corrosion-resistant, and dimensionally accurate. Those features making them be essential structural and connection components in modern steel construction.

Product Description

C Purlins: This product is “C”-shaped steel channel, which symmetrical design is easy to install. Now this product is widely used for roof and wall purlins in medium to small-span buildings, as well as in light steel frames.

Z Purlins: This is a “Z”-shaped cross-section channel steel with inclined flanges, which allowing overlapping joints for continuous spans. This product is ideal for large-span and high-load roof and wall systems, especially in logistics centers and airport terminals usage.

U Purlins:

This “U”-shaped channel steel, which with higher, vertical flanges that offering strong integrity. This product is commonly used for frame reinforcement, like door/window frames, curtain wall studs, and equipment supports.
