Steel structures are composed of steel materials and represent a primary type of architectural structure. They are primarily made up of components such as beams, columns, and trusses-fabricated from structural steel shapes and plates-and undergo rust removal and anti-corrosion treatments such as silanization, manganese phosphating, washing and drying, and galvanizing. Individual components are typically connected via welding, bolting, or riveting.
Due to their relatively low self-weight and ease of construction, steel structures are widely used in large-scale industrial plants, stadiums and arenas, super-high-rise buildings, and bridges. As steel structures are susceptible to corrosion, they generally require rust removal, galvanizing, or protective coatings, as well as regular maintenance. The steel used must possess good mechanical and fabrication properties; materials such as Q235 carbon steel and 16Mn low-alloy steel meet these requirements.
The durability of steel is affected by factors such as corrosion and high temperatures; protective measures include galvanizing and anodic protection.
