Structural steel is a type of construction made up of steel materials and is one of the primary types of building structures. It is primarily composed of components such as steel beams, columns, and trusses, which are made from shaped steel and steel plates. Rust removal and prevention techniques, such as silanization, pure manganese phosphate conversion, water washing and drying, and galvanizing, are used. The components or parts are usually joined together using welds, bolts, orScrew pinConnect. Due to its light weight and simple construction, it is widely used in large factory buildings, venues, and ultra-high-rise structures. Steel structures are prone to rust, so they usually require rust removal, galvanizing, or painting, and regular maintenance is necessary.
