Product Overview

Cold-formed Z section steel (Z purlin) is continuously roll-formed from galvanized or black annealed steel strips. Thanks to the special Z-shaped profile, components can closely overlap each other. It performs better under continuous-span load than C-section steel, widely adopted for large-span steel building enclosures. Custom cutting length and pre-punched bolt holes are available.

Key Advantages

1. Superior mechanical performance Higher section moment of inertia, ideal for long-span roof structures. Overlapping connection forms continuous load-bearing system and saves steel consumption.
2. Easy lap installation Ends can be directly overlapped without extra connectors, simplifying construction and shortening working time.
3. Optional anti-corrosion treatment Galvanized steel strip as raw material provides reliable rust resistance for outdoor and humid environments.
4. Flexible customized specifications Height, flange width, thickness and length can be customized to meet various engineering designs.

Application

Mainly used as roof purlins and wall purlins for large-span steel workshops, warehouses and prefabricated buildings. Also applicable for large supports and platform components.
