Z Shaped C Shaped Steel Roof Purlins Steel Structural Component

Z-Shaped Steel Purlin C-Shaped Steel Purlin Steel Structural Component

A horizontal roof beam perpendicular to a truss or rafter and used to support rafters or roofing materials. A transversely bent (usually bi-directional) member, usually designed as a single-span, simple-supported purlin.Common purlins are solid web type and light steel truss type.

Purlins can be divided into two main purlins and secondary purlins.
The primary purlin is installed on the roof and the column beams of the external wall structure, and the secondary purlin is used to connect the roof board and the external wall board to the foundation structure. The primary and secondary purlins are the main structural components commonly used in modern steel structure design.

We have strict Quality Control Department to control the quality including inspection for raw steel material & welding quality & painting. Third-party inspection is welcomed.
