Materils and Accessories:
  1. Structural Steel: Hot-rolled sections (e.g., H-beams, I-beams, channels) and cold-formed thin-walled steel are widely used. Hot-rolled steel, such as Q345B or ASTM A992, offers high strength for primary load-bearing members like columns and beams . Cold-formed steel, fabricated by bending thin steel sheets (2–6mm thick), is ideal for lightweight structures like roofing purlins and wall studs .
  2. High-Strength Bolts: These are critical for connections, categorized into friction-type and bearing-type. Friction-type bolts (e.g., ASTM A325) transfer loads via frictional resistance between clamped surfaces, while bearing-type bolts (e.g., ASTM A490) rely on direct shear and bearing . They are typically made of alloy steel with grades 8.8 or 10.9, ensuring reliable load transfer .
  3. Welding Materials: Consumables like electrodes (e.g., E50XX for Q345 steel) and welding wires (e.g., H08MnA) must comply with AWS or GB standards to ensure weld strength and ductility . Flux-cored wires and submerged arc welding (SAW) are commonly used for high-efficiency fabrication .
  4. Coatings: Anti-corrosive coatings (e.g., zinc-rich primers) and fire-resistant paints (e.g., intumescent coatings) protect steel from environmental degradation. These must meet ISO 12944 (corrosion protection) and GB 14907 (fire resistance) standards .
