Structural steel is a category of steel construction material that is produced with a particular cross section or shape, and some specified values of strength and chemical composition. Structural steel composition, strength, size, shape, strength, and storage are controlled in most advanced countries. The word structural steel includes a broad variety of low carbon and manganese steels that are used in great numbers for civil and marine engineering applications. Numerous structural steels also include minor quantities of significant additions of other elements like Nb, V, Ti and Al. These are called High Strength Low Alloy or micro-alloyed steels. Structural steels are manufactured in section and plate shapes and are normally used in bridges, buildings, ships, and pipelines.

Types of Structural Steel

After iron, carbon is the most important element in steel. The increase of carbon produces materials with high strength and low ductility. The techniques used for the production of steel are high- computerized stress analysis, precision stress analysis, and innovative jointing. The types of structural steel sections normally used are beams, channels, flats, and angles. The main kinds of structural steel are generally categorized according to the under mentioned categories of chemical composition:

    Carbon-manganese steels: The major chemical ingredients are iron, carbon, and manganese. These are normally called mild structural steels or carbon steels. The strength and ductility are high, and being economical is therefore widely used.

    High-strength, low-alloy steels: This is a recent development in the steel industry. Chemical elements are added to improve the strength.
