Key Advantages
  • Superior Load-Bearing Capacity - Adopting high-strength steel with yield strength up to 345–690MPa, supporting heavy cranes (25t, 50t, 100t+), heavy-load floors, and long-span column-free spaces.
  • Excellent Seismic & Wind Resistance - Outstanding plasticity and toughness, meeting seismic fortification intensity 8+, ensuring safety in high-seismic and coastal strong-wind areas.
  • Factory Prefabrication & Efficient Delivery - Full-process factory prefabrication, shortening construction period by 30%–60% compared with concrete structures.
  • Maximized Space Utilization - Small cross-section and high bearing capacity enable extra-long span and super-high clearance, improving usable area and logistics efficiency.
  • Long-Lasting Anti-Corrosion & Durability - Standard surface treatment: sandblasting Sa2.5 + zinc-rich epoxy primer + epoxy intermediate coat + polyurethane topcoat.
  • Eco-Friendly & Low-Carbon - Dry construction minimizes pollution. Steel is 100% recyclable, fully compliant with global green building policies.
