Types of Structural Steel

structural steel cross sections on a bridgeAbout 25% of a building’s construction is made up of structural steel, which is used in beams, columns, frames, bars, and plates. Differing types of structural steel are used depending on the application, as some are stronger than others and some offer better corrosion resistance. Here is a breakdown of common types of structural steel:


Known for low cost, exceptional yield strength, and easy machinability, A36 structural steel is one of the most widely used steel types in the industry. It can elongate to about 20% of its original length and is commonly used in columns, beams, and decking.


A high-strength low-alloy (HSLA) steel, A572 structural steel plate offers a similar tensile strength to A36 but weighs less, making it a popular material for transmission towers, bridges, and similar structures. Its low-alloy makeup also makes it easy to weld.


A588 structural steel has a greater yield and tensile strength (>46,000 psi) than A36 and A572 and better resists corrosion due to exposure to the elements. Therefore, it is the ideal structural steel material for outdoor applications.


With a yield strength of 100,000 psi, A514 structural steel is one of the strongest of its kind. This high-performance option can elongate between 16–18% of its original form and is typically used to support heavy loads in high-wear applications.
