Product Description

Q355 Angle-Steel Workshop Steel Structure, Seismic Large-Span Sheds & Workshops up to 65m

 

Main Features

A Q355B angle-steel truss and lattice-frame system for large-span sheds and workshops, offering high stiffness with low steel tonnage.

  • Q355B angle steel (equivalent to S355JR), yield 345 MPa

  • Truss / lattice column-and-rafter construction

  • Max clear span up to 65 m, column-free interior

  • High stiffness-to-weight ratio, economical steel tonnage

  • Open, half-open or fully enclosed layouts available

  • Bolted splices and gusset-plate connections

  • Seismic design per EN 1998; wind load up to 35 m/s

  • Sa2.5 blasting + epoxy-zinc coating (HDG optional)

  • Optional roof/wall panels, insulation, ventilated ridge

  • Designed to GB 50017 / EN 1993 / EN 1090-2
