C-Purlin is a horizontal beam or bar used for structural support in buildings, most commonly in a roof.A Purlins are supported either by rafters or the walls of the building. Steel Purlins are light weight, dimensionally stable, accurate and straight. They expand and contract reasonably in extreme temperature changes. The cold roll forming process results in high degree of consistency and accuracy in the dimension of the sections. We supply all our C purlins in high quality JSW galvanised iron steel. Coating options available in 80gsm, 120gsm, 180gsm and 275gsm as per requirements.
