Structural steel is a composition of steel materials and is one of the main types of architectural structures. It is primarily made up of components like steel beams, columns, and trusses, which are fabricated from sections and plates. Rust and corrosion prevention is achieved through processes such as silanization, pure manganese phosphate coating, water washing and drying, and galvanizing. The components or parts are typically connected using welds, bolts, or rivets. Due to its light weight and ease of construction, it is widely used in large factory buildings, stadiums, and ultra-high-rise structures. Structural steel is prone to rusting, so it usually requires rust removal, galvanizing, or coating, and regular maintenance.
