Steel sizes range from tiny to extra large, depending on the application. Tiny steel sizes refer to wire or flat sheets that are thinner than 0.05 millimeters. The thickness of the steel generally increases with size, up to about 140 millimeters for extra large steel sizes.
Small steel sizes range in thickness from 0.05 to 6 millimeters. This type of steel is often called sheet steel and is often used in car bodies, appliances and ammunition boxes. It is also used in larger structures, such as bridges and buildings, when it may be combined with other materials such as concrete.
Medium steel sizes generally refer to steel plates that range from 6 to 40 millimeters in thickness. High-strength steel is commonly used in these plates and they are used extensively in construction, shipbuilding, and other industrial applications.
Large steel sizes range from 40 to 140 millimeters. These sizes are used for large-scale construction projects such as bridges and skyscrapers, as well as specialized applications such as naval vessels and railroad cars.
Extra large steel sizes are those over 140 millimeters in thickness. This type of steel is usually found in heavy equipment and large machinery, such as cranes and bulldozers.
No matter what type of steel is needed for a particular project, there are steel sizes available to fit the application. Whether it is tiny steel for electronics or extra large steel for heavy machinery, steel is one of the most versatile and important materials in modern construction.
