Z & C Purlins
Overview
Top Z & C Purlin Manufacturers and Suppliers are essential structural components used in Pre-Engineered Buildings (PEB), industrial sheds, and roofing systems to provide strong and stable support for roof and wall panels. They form the secondary framing system that transfers roof and wall loads to the main structural framework.
At BSSM Infra, we manufacture and supply high-quality Z and C Purlins made from high tensile galvanized or cold-formed steel, ensuring superior strength, accuracy, and durability. Our purlins are designed for lightweight construction, easy installation, and long-term structural performance, making them ideal for a wide range of industrial and commercial projects.
What Are Z & C Purlins?
Purlins are horizontal beams or members placed along the length of a roof or wall, attached to the main frame to support roofing sheets and wall claddings.
Z Purlins: Have a “Z” shaped profile, suitable for overlapping and continuous spans.
C Purlins: Have a “C” shaped profile, ideal for single-span applications such as wall girts and roof supports.
Both types are designed for high load-bearing capacity, easy handling, and fast installation, ensuring efficient and reliable performance in steel structures.
