Description

Seismic-Resistant Prefabricated Steel Buildings, Quick-Install Green Large-Span Design

Main Features

  • Engineered for seismic & extreme environmental loads — Designed to seismic fortification intensity 8 (GB 50011), with wind-load, snow-load and structural FEA independently verified by our in-house engineering team; adaptable to typhoon, hurricane and desert-corrosion site conditions.

  • High factory prefabrication, fast on-site erection — ≥85% factory prefabrication rate with ≥78% module standardization; bolt-up numbered assemblies that cut construction time by 55–72% versus conventional cast-in-situ concrete.

  • Internationally certified fabrication quality — EN 1090 CE-marked (Execution Class up to EXC 3), ISO 3834 / ISO 15614 welding-qualified, AWS D1.1 code-compliant; audited under ISO 9001 / 14001 / 45001 integrated management system.

  • Heavy-industry grade primary steel — Q355B main frames (equivalent to S355JR / A572 Gr.50), with full mill-material traceability; hot-dip galvanized or multi-coat epoxy primer systems specified per ISO 12944 corrosivity categories (C1–C5).

  • Large clear-span, future-expandable layout — Clear spans up to 60 m+ without interior columns; modular jointing supports later extension, mezzanine insertion and functional reconfiguration.

  • Green, low-waste erection — Structural steel is ≥85% recyclable; minimal on-site wet work and construction waste; optional insulated wall/roof panels (PU / EPS /rockwool) to meet international energy-efficiency requirements..

Advantages

  • Highly modular design enables factory-scale production with stable, controllable quality.

  • Strong adaptability — optimized design tailored to regional climatic characteristics.

  • Significant cost advantage — lower whole-life-cycle cost than conventional buildings.

  • Flexible expansion capability for post-occupancy modification and functional reconfiguration.

  • Standardized production ensures consistent building quality, safety and reliability.

  • Excellent seismic performance — meets building safety requirements in earthquake-prone regions.

  • Eco-friendly construction — reduced site waste and high material recyclability.

Core Applications

  • Power-plant boiler structures & heavy industrial steel frames(coal-fired / thermal / solar-thermal).
  • Coal yard enclosures, large-span space frames & roundhouse storage domes.
  • Industrial parks & manufacturing plants (smelting, processing, assembly).
  • Heavy-duty workshops, machine shops & production halls.
  • Port / wharf / cargo-handling steel structures.

Standard Applications

  • Logistics centers & distribution warehouses.

  • Aircraft hangars & aviation maintenance facilities.

  • Office buildings & commercial complexes.

  • Schools, hospitals & public service facilities.

  • Indoor stadiums, gymnasiums & natatoriums.

  • Hotels, exhibition centers & convention halls.

Specilized / Climate-Engineered Applications

  • Seismic-prone region structures (fortification intensity 8 and above).

  • Hurricane / typhoon-resistant high-wind designs.

  • Heavy snow-load roof systems (cold-climate regions).

  • Desert / high-temperature corrosive-environment coatings.

  • Rapid-deploy emergency & disaster-relief buildings.
