Z & C Purlins

Our purlin is manufactured with supreme quality materials and latest techniques in compliance with the market standards. This purlin is examined on various parameters in order to assure its flawlessness. We offer this purlin with various specifications options as per the customer’s needs.

Purlins girts & eve struts are secondary structural members used to support the wall and roof panels. Alfaa purlins are used on the roof, girts are used on the walls and eve struts at the intersection of side walls and roofs.Purlins, girts and eave struts are designed in accordance of the American Iron and Steel Institue (AISI) then cold formed design manual.Sections may be used over single spans unlapped continuous and lapped continuous span in multi bay buildings. Z&C purlins are available in two Standard Finishes i.e., Red Oxide, Galvanized.
