Specification
Steel structure technical specifications

Steel-structured buildings represent an innovative construction method compared to conventional buildings. The entire structure is fabricated from steel, consisting primarily of steel beams, columns, trusses, and other components made from section steel and steel plates. Components are connected through welding, bolts, or rivets. Due to their lightweight nature and simple structures, they are widely used in large-scale factories, stadiums, super-tall buildings, and other applications.

Structural Types:
  • Portal Rigid Frame: Simple structure with clear force-transmission paths, enabling fast construction and cost-effectiveness. Ideal for industrial buildings and small-scale commercial structures.
  • Frame Structures: Highly flexible for creating large open-plan spaces, popular in multi-story commercial buildings, shopping malls, and conference centers.
  • Truss Structures: Combine small-cross-section components into robust units, perfect for long-span applications like stadium roofs and industrial workshops.
  • Grid Structures: Feature an intricate network of rods offering high rigidity and excellent seismic resistance, commonly used in gymnasiums, exhibition halls, and airport terminals.
