Our range of Sigma Purlins offer four convenient depths 145mm, 175mm, 205mm & 225mm and can be produced in thicknesses up to 2.0mm in hot dipped galvanised steel to BSEN 10326:2004 & BS 10143:1993. The minimum grade of steel used is S450GD, with Z275 zinc coating. Sigma purlins can be produced with 14mm dia. holes which reduce the cost of bolts & nuts and also due to the symmetrical design Sigma purlins have no handing therefore easier to order and less problems identifying purlins on site. Health & Safety is always paramount on site and with Sigma purlins sitting above the cleats on the roof this aids the purlin erector whilst bolting the purlins to the cleats.
