Steel structures of steel materials, are a primary type of building structure. They primarily consist of beams, columns, trusses, and other steel profiles and plates. Protective treatments such as silanization, manganese phosphate coating, washing, drying, and galvanization are applied. Components are connected via welding, bolts, or rivets. Due to their lightweight and ease of construction, they are widely used in large factories, stadiums, and super-tall buildings.

Steel exhibits high strength, lightweight properties, excellent overall rigidity, and strong anti-deformation capabilities, making it ideal for large-span, high-rise, and ultra-heavy structures. Its uniform material properties and isotropy make it an ideal elastic body, aligning with basic mechanical assumptions in engineering. Steel also demonstrates strong plasticity and toughness, accommodating significant deformation under dynamic loads. Its high industrialization level enables highly mechanized specialized production.

Research should focus on developing high-strength steel to significantly improve yield strength. Additionally, new steel profiles like H-beams (wide-flange beams), T-beams, and profiled steel sheets must be rolled to meet the demands of large-span structures and super-tall buildings.
