Structural steel is steel that meets specific strength and formability grades. Formability is expressed as elongation after interruption of the tensile test. Structural steels are generally used for applications such as load-bearing, where the strength of the steel is an important design criterion.
Structural steels can be subdivided into: carbon structural steels, high-quality carbon structural steels, low-alloy high-strength structural steels, alloy structural steels, spring steels, weathering structural steels, chip-prone structural steels, non-tempered mechanical structural steels, etc.
Skyscrapers or high-rise buildings are constructed using structural steel because of its constructability and high strength-to-weight ratio.

Structural steel is mainly used for construction purposes thanks to the rigidity and high strength to weight ratio. Structural steel is used to construct residential and commercial buildings, warehouses, aircraft hangers, hospital and school buildings, metro stations, stadiums, bridges, etc. Construction of these structures is done with the help of structural steel design components such as channels, beams, angles, and plates.
Structural steel has high levels of elasticity, strength, ductility, and corrosion resistance that helps in vehicle building. This robust material is used for engineering and manufacturing of transport vehicles such as trucks, aircrafts, ships, trains, etc. Structural steel is also used in manufacturing other transport related components such as rails, ship and jet engine components, aircraft undercarriages, anchor chains, etc.
Various sectors of energy such as nuclear, wind power, electric, mining, oil and natural gas make use of structural steel for manufacturing different components. The major reason for using structural steel is its ability to corrosion, fire, and weather resistance which reduces several risks and accidents at sites where they are used. Structural steel is used for manufacturing and creating transmission towers, turbines, electromagnetic shields, electricity pylons, oil and gas wells, and pipelines in these industries.
The ductile and malleable properties of structural steel make it possible to mold and shape them in several ways and forms. Also, it is a cost-effective material considering the benefits structural steel designs provide. Structural steel is often used for the following purposes too:
