Steel Structure Buildings Specification
Design Standards:
Follow Chinese steel structure building architectural standards such as GB 50017 or regional equivalents, which define load calculations, material selection, and seismic/wind resistance requirements.
Structural components (beams, columns, trusses) must adhere to strength, stability, and deflection limits based on usage (e.g., residential, industrial).
Material Requirements:
Use structural-grade steel (e.g., Q355b Q235b) with certified yield strength, tensile strength, and elongation properties.
Fabrication & Construction:
Components must meet dimensional tolerances specified in standards.
Welding/bolting procedures ensure joint integrity.
Fire Protection:
Apply fire-resistant coatings or cladding to achieve required fire ratings (e.g., 60–90 mins), complying with local building codes.
Quality Control & Testing:
Non-destructive testing (ultrasonic, radiographic) for critical welds.
Documentation of material certifications, inspection reports.
