Product Description
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, typically designed as a single-span, simple-supported purlin. Common purlins include solid web type and light steel truss type.
Purlins can be divided into two main categories: primary purlins and secondary purlins. The primary purlin is installed on the roof and the column beams of the external wall structure, while the secondary purlin connects the roof board and external wall board to the foundation structure. These components are essential in modern steel structure design.
