Aluminium Zinc Coating
The mild steel substrate is continuously hot dipped in a formulation of Aluminium (55%) Zinc (43.5%), and Silicon (1.5%). The combination of aluminium and Zinc increases the sacrificial properties therefore extending the service life span of a steel roof of up to 4 times that of galvanised steel. The aluminium components of the coating provide a tough physical barrier between the extreme atmospheric conditions and the inner core of steel. The Zinc in the coating protects the steel where exposed.
The mild steel substrate is continuously hot dipped in an almost pure Zinc formulation. Zinc has inherent sacrificial properties and corodes first before the mild steel core. Galvanising offers almost twice the service life than that of the steel substrate. A unique spangle appearance gives Galvanised steel its signature in the market.
IBR is a square fluted profile and the broad flute offers excellent drainage. IBR can be used for roofing and side cladding and can be Bullnosed or Cranked to customers specifications. IBR can be used for residential, commercial and industrial roofing in Galvanised, Aluzinc and Pre-painted Aluzinc sheets.
