What is Structural Steel Fabrication?

Structural steel fabrication refers to the process of cutting, bending, and assembling steel components to form a complete structure. These structures serve as the skeleton of large-scale projects such as bridges, industrial plants, and skyscrapers. Skilled technicians use specialized machinery to ensure precision in the fabrication process.

The Structural Steel Fabrication Process

The fabrication process for steel involves several critical stages that turn raw steel into functional building components:

1. 1. Cutting: In the first stage, steel is cut into the desired sizes and shapes using plasma cutting, water jet cutting, or shearing to ensure precision.

1. 1. Bending: After cutting, the steel may need to be bent for specific architectural designs. Press brakes and specialized machines are used to bend steel without compromising its strength.

1. 1. Welding: Welding is key in the fabrication process, as it joins steel parts together. Techniques like MIG and TIG welding create durable joints that can withstand immense weight and pressure.

1. 1. Assembly: Once the steel is cut, bent, and welded, it is assembled either in a fabrication shop or directly at the construction site. During this stage, quality control checks are performed to ensure the structure’s durability.
