Steel structures are structures composed of steel materials and represent one of the primary types of architectural structures. The structure mainly consists of components such as beam steel, steel columns, and steel trusses made from structural steel profiles and steel plates, and undergoes rust removal and anti-corrosion processes including silanization, pure manganese phosphating, water washing and drying, and galvanizing. These components or parts are typically connected by welds, bolts, or rivets. Due to their light weight and ease of construction, they are widely used in large-scale factories, stadiums, ultra-high-rise buildings, and other similar applications.

Steel is characterized by high strength, light weight, excellent overall rigidity, and strong deformation capacity, making it particularly well-suited for constructing large-span, ultra-high-rise, and ultra-heavy structures. The material exhibits good homogeneity and isotropy, behaving like an ideal elastic body and closely conforming to the basic assumptions of general engineering mechanics. Moreover, steel has excellent plasticity and toughness, allowing for significant deformation and enabling it to withstand dynamic loads effectively. Construction periods are short, and the material boasts a high degree of industrialization, permitting highly mechanized and specialized production.
