Structural steel is a type of construction composed of steel materials and is one of the main types of building structures. It primarily consists of components such as steel beams, columns, and trusses made from shaped steel and steel plates, and employs rust prevention techniques like silanization, pure manganese phosphate conversion, water washing and drying, and galvanizing. The components or parts are usually connected by welds, bolts, or rivets. Due to its light weight and ease of construction, it is widely used in large factories, stadiums, skyscrapers, bridges, and other fields. Structural steel is prone to rust, so general structural steel requires rust removal, galvanizing, or painting, and regular maintenance is necessary.
