C and Z Purlins are cold-formed steel secondary members used in Pre-Engineered Buildings to support roof and wall sheeting and to transfer loads safely to the primary steel frames. Both sections are factory-formed with high dimensional accuracy and are designed based on actual span, wind load and service requirements
Z purlins are mainly used where continuity and higher structural efficiency are required, as they can be lapped over supports to form a continuous system
C purlins are commonly used for shorter spans and non-continuous framing such as wall girts and edge members
