Structural steel is a type of construction composed of steel materials and is one of the primary architectural structural types. It primarily consists of steel beams, columns, trusses, and other components made from sections and plates of steel, and it employs rust removal and prevention techniques such as silanization, pure manganese phosphate conversion, water washing and drying, and galvanizing. Components or parts are usually joined using welds, bolts, orrivetConnection. Due to its light weight and simple construction, it is widely used in large factories, stadiums, and ultra-high-rise buildings. Steel structures are prone to rust, so general steel structures require rust removal, galvanizing, or painting, and regular maintenance is necessary.
