Construction Details
Galvanised Steel C Sections
Upper lip of C Purlin should face upper slope. Outside lip of girts should face upward.
SK C Purlin
SK C Purlin is produced from Hi-Tensile galvanised steel. The technology used in cold roll forming process ensures stability and technology used in cold roll forming process ensures stability and accuracy in the dimensions and lengths.
The Purlins are supplied cut to length and pre-punched hole(s) to ease for design roofing, cladding supports and light weight framed structures.
