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
