C and Z Purlins
Purlin System
Purlin systems include a main purlin and a secondary purlin. The main purlin is used to install the roof and outside wall column and beam. The secondary purlin fixes the roof sheet and wall panel to the structure. The most common types of purlins are C and Z purlins which are cold formed from galvanized iron sheet for maximum strength. Our C and Z Purlins provide you with strong and secure connections for your steel structured buildings.
