Structural steel is designed to have a high strength to weight ratio, or specific strength, which means it is not heavy but can bear a lot of weight. It is cost-effective and durable, which is why it is used in a broad range of projects. Because it is an alloy, there are several types available and determining which to use depends on the application. 

The Types

High-Strength & Low-Alloy 

These types have chemical elements added to improve their strength and resistance to corrosion. The elements added include manganese, chromium, nickel, molybdenum, nitrogen, vanadium, and titanium. High-strength and low-alloy steel are commonly used in structural shapes and plates.

Carbon

Carbon steel, or carbon-manganese steel, is commonly used in tubing and structural pipe. It is strong and highly ductile, which means its shape can be changed easily without damaging the metal’s integrity. This type is available in four categories: low carbon (less than 0.3 percent), medium-carbon (0.3 to 0.6 percent), high-carbon (0.6 to 1 percent), and ultrahigh carbon (1.25 to 2 percent).

Quenched & Tempered Alloy

This type is used for structural purposes. It has undergone a quenching and tempering heat treatment, which involves heating the material and rapidly cooling it. This process makes the steel more malleable and weldable without sacrificing hardness.

The Applications

Structural steel is useful in a wide range of applications. It makes an appearance in construction as steel beams, bars, plates, frames, girders, and more are used to design and build large structures. It is used in the transportation industry for components in trucks, aircraft, trains, ships, transmissions, and jet engines. The energy industry uses structural steel in transmission towers, gas and oil wells, wind turbines, electromagnets, and more.
