Product Description

Q355 Workshop Steel Structure, Seismic Steel-Framed Structures up to 60m Span

 

Main Features

A Q355B steel-framed workshop system engineered for 60 m large-span buildings in seismic zones, with ductile design and code-compliant detailing.

  • Q355B (S355JR equivalent) high-strength steel, yield 345 MPa
  • Clear span up to 60 m, column-free interior
  • Seismic design per EN 1998 / GB 50011
  • Moment-resisting frame with ductile beam-column joints
  • Cross-bracing or eccentric bracing for lateral load resistance
  • Full-penetration welds on seismic-critical joints, UT/MT tested
  • Drift and inter-story displacement controlled to code limits
  • Sa2.5 blasting + epoxy-zinc coating
  • Roof/wall envelope with optional insulation
  • Designed to GB 50017 / EN 1993 / EN 1090-2

Advantages

  • Large-span seismic design: up to 60 m column-free space in earthquake-prone regions.

  • Ductile Q355B frame with moment-resisting joints and engineered bracing.

  • Quality assurance: UT/MT NDT on all seismic-critical welds per EN 1090-2.

  • Code-compliant: designed to EN 1998, GB 50011 and ASCE 7 as required.

  • Fast bolted erection reduces on-site time in remote seismic zones.

  • Certified to EN 1090-2 + ISO 9001; SGS/BV inspection available.

  • Factory strength: 100 t crane, 50,000 t/year, 80–90% export share.

  • Proven in seismic projects across Southeast Asia, Mediterranean and Latin America.

 

Applications

  • Industrial workshops in seismic zones

  • Large-span warehouses and distribution centers

  • Heavy manufacturing plants in earthquake-prone regions

  • Steel structure factories and fabrication yards

  • Logistics buildings in seismic belts

  • Automotive and assembly plants

  • Public and emergency facilities in high-seismic areas

  • Multi-story industrial buildings in seismic zones

  • Industrial park facilities in Southeast Asia, Mediterranean, Latin America

  • Warehouses and workshops designed to EN 1998 / ASCE 7
