Galvanised Corrugated Sheet


Galavanised cogurrated sheets are proved to be light, strong, corrosion-resistant, and easily transported, and particularly lent itself to prefabricated structures.

  • G.C.Sheet is also a common construction material for industrial buildings throughout the world.
  • For roofing purposes, the sheets are laid somewhat like tiles, with a lateral overlap of two or three corrugations, and a vertical overlap of about 150 mm, to provide for waterproofing.
  • Although galvanising inhibits corrosion of the underlying steel, rusting will be inevitable, especially if the local rainfall is at all acidic in nature.
  • So for example, corrugated iron sheet roofing will start to degrade within a few years despite the protective action of the zinc coating in corroding preferentially.Stair Protection.
  • Other environments which lower the lifetime of galvanised iron roofs and similar products includes marine locations, where the high electrical conductivity of sea water will encourage and increase the rate of attack.
  • Nevertheless, corrugated steel roofs can last for many years if further protected by a paint layer.
