Apart from Zincalume roofing we also do IBR and corrugated steel flat roof replacements. Steel flat roofs have to be protected by the sun, wind and rain with a finish called Silvacote. Unlike Zincalume roof sheets steel roof sheets don't have the attributes and qualities to withstand severe long term weather without this products. Silvacote reflects the UV rays preventing the roof sheets from getting to hot and melting the torch on waterproofing system that welds the roof sheets to the parapet walls.
