Corrugated galvanised iron, commonly abbreviated (CGI) is a building material composed of sheets of hot-dip galvanised mild steel, cold-rolled to produce a linear corrugated pattern in them. The corrugations increase the bending strength of the sheet in the direction parallel to the corrugations, but not across them. Normally each sheet is manufactured longest in its strong direction.
CGI is lightweight and easily transported. It was and still is widely used especially in rural and military buildings such as sheds and water tanks. Its unique properties were used in the development of countries like Australia from the 1840s, and it is still helping developing countries today.
Corrugated galvanised iron today: The corrugation process is carried out using the process of "Roll Forming". This modern process is highly automated to achieve high productivity and low costs associated with labour. In the corrugation process sheet metal is pulled off huge coils through rolling profiler that form the corrugation. After the sheet metal passes through the rollers it is automatically cut off at a desired length. The standard shape of corrugated material is the round wavy style.
Many materials today undergo the corrugation process. The most common materials are ferrous alloys but may also span to stainless steels. Copper and aluminium are also used with great results. Regular ferrous alloys are the most common due to price and availability. Common sizes of corrugated material can range from a very thin 0.14mm to 0.8mm. Corrugated galvanised iron forms only one of our products.
