These sheets were initially made from corrugated iron or galvanized iron (CGI). CGI is also the name of two different materials – galvanized wrought iron and mild steel.

Initially, galvanized wrought iron was used to make corrugated galvanized iron. However, between 1890 and 1910, mild steel replaced galvanized iron due to improved steel-making and processing.

Corrugating technique for strengthening was known to human civilization for centuries. However, a successful corrugating approach came to light only during the early 1840s. During this time, manufacturers used to press the sheets to create the grooves. This method of grooving was successful, but the results were not uniform. Therefore, a successful grooving technique for uniformity was developed much later.

Despite being more robust and cheaper than other common materials, iron and steel carry the risk of corrosion readily in air and water. However, using the protection of galvanization, they were made into a more durable building material. In addition, galvanized iron sheets were robust, lightweight, and easy to transport. Thanks to these qualities, they achieved the status of a staple building material in various countries, including the US, New Zealand, Australia, and India.

During 1850, Australia began to use corrugated galvanized iron sheets for roofing and wall cladding. Soon, they became a part of the national identity of the country.
