  • Product Detail

Steel purlin is usually made of cold-formed steel that is thin enough to put screws through. Cold-formed steel is made by rolling or pressing thin sheets of steel into the desired shape. Usually in "C" shape or "Z" shape. Purlins are most commonly used in Metal Building Systems, where Z-shapes are utilized in a manner that allows flexural continuity between spans.

Purlins are secondary steel framing members used for roof and wall support as well as a header, sill, brace, and more.
