What is Structural Steel

Steel structure is a structure composed of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of shaped steel and steel plates, and adopts rust removal and anti-rust processes such as silanization, pure manganese phosphating, washing and drying, and galvanizing.

In the steel framework, primary load-bearing elements like steel columns, beams, and frames carry the bulk of the structure’s weight and stress. Meanwhile, auxiliary elements like steel plates, brackets, and pallets provide essential connectivity, support, and stability. Typically, these parts are assembled using methods such as welding, bolting, or riveting.

Steel structure cutting method

Steel structures often need to be cut during processing. Flame cutting, plasma cutting, laser cutting and water cutting are all commonly used cutting methods.
