Steel is a ferrous metal and is an alloy of iron and carbon, as well as potential other elements. It has a very high tensile strength. Steel has been used in the construction industry for over a century.
The core material for making steel is iron, which is found in iron ore. Iron is extracted from iron ore in blast furnaces through the smelting process, while controlling for the content of carbon. The molten steel is usually further processed before being cast into sheet. These steel sheets are then corrugated using roll forming. The corrugated steel sheets are finally galvanised by applying a coat of zinc crystals on their surface to significantly improve their resistance to corrosion.
Corrugated steel sheets are widely used in the construction industry, mainly as roofing, cladding, separations and permanent formwork.
