Corrugated galvanized iron or steel, colloquial corrugated iron (almost universal), creeping tin (taken from British military slang), barrel (Caribbean English), corrugated sheet metal (North American) or tin (Australian), sometimes abbreviated CGI is a type of construction The material, consisting of hot dipped galvanized mild steel sheet, is cold rolled to create a linear ridged pattern in it.Although it is still commonly known as "iron" in the UK, the material used is actually steel (an iron alloy with carbon added for strength, usually 0.3% carbon) and only surviving older plates may actually be 100% iron Made.Corrugations increase the bending strength of the sheet in a direction perpendicular to, but not parallel to, the corrugations, since the steel must be stretched to bend perpendicular to the corrugations. Usually each sheet is made longer in its strong direction.

Corrugated galvanised iron

CGI is lightweight and easy to transfer.It was and is used extensively, especially in rural and military constructions such as sheds and water tanks. Its unique properties have been used in the development of countries such as Australia since the 1840s and are still helping developing countries today.Corrugated galvanized iron sheet is also called corrugated steel sheet or corrugated steel metal.This was used as a trench roof for army soldiers to protect them from enemy fire.Also serves as a roof for the Commander's Box.The book "Infantry Combat" uses the term "corrugated steel plate", so we can assume that corrugated galvanized iron is used in the military as corrugated steel.

Corrugation today

Today, the corrugation process is performed using the roll forming process.This modern process is highly automated to achieve high productivity and low cost associated with labor. During corrugation, sheet metal is pulled from giant rolls and passed through rolling dies that create the corrugations.After the metal sheet passes through the drum, it is automatically cut to the required length.The traditional shape of corrugated material is a round wave, but different molds form it into various shapes and sizes. Industrial buildings are often constructed and clad from trapezoidal metal panels.Many materials today are corrugated.The most common materials for corrugated iron are ferrous alloys such as stainless steel, aluminum and copper.Plain ferroalloys are the most common due to price and availability. Common sizes for corrugated material range from the very thin 30 gauge (0.012 inches, 0.3 mm) to the relatively thick 6 gauge (0.1943 inches, 5 mm).Thicker or thinner gauges can also be produced.Other materials, such as thermoplastic and fiberglass-reinforced plastic sheets, can also be made corrugated.Transparent or translucent products allow light to pass through underneath.
