Structural steel is a type of construction composed of steel materials, one of the primary architectural structural types. It primarily consists of components such as steel beams, columns, and trusses made from sections and plates, which are treated with processes like silane coating, pure manganese phosphate conversion, water washing and drying, and galvanizing for rust prevention. 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, venues, skyscrapers, bridges, and other fields. Structural steel is prone to rust, so it typically requires rust removal, galvanizing, or painting, and regular maintenance is necessary.
