Steel structures are composed of steel materials and are one of the main types of architectural structures. They consist mainly of steel beams, columns, trusses, and other components made from section steel and steel plates, and are treated with rust prevention methods such as silane coating, pure manganese phosphate coating, water washing and drying, and galvanizing. Components or parts are usually joined using welds, bolts, orScrewsConnectivity. Due to its light self-weight and simple construction, it is widely used in large factories, venues, 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.
