GS Plate Welded Beams

Go Steel I/H Beams – Parallel Flange Sections

World over, parallel flange beams are the increasingly preferred standard for large constructions owing to their superior strength, cost-savings, enhanced durability, and higher load-bearing capacity.

GS Beams are now the most sought-after primary sections recommended by structural engineers, architects, and construction companies throughout India.

Applications

  • Multi-storey buildings
  • Bridges
  • Flyovers
  • Rail projects
  • Power plants
  • Refineries
  • Airports
  • Industrial sheds

Advantages of GS Plate Welded Beams

  • Enhanced life cycle and durability.
  • Time-saving as manufactured on automatic online cutting and welding lines.
  • Steel savings in excess of 20% as lower sectional weight beams can achieve higher load-bearing capacity.
  • Ideal for bolted or fabricated construction.
  • Offer tremendous flexibility in design as beams are entirely custom-made.
  • Shot blasted and painted; aesthetically superior.

Product Specification

  • Flange width: 200 mm to 1500 mm
  • Web thickness: 6 mm to 60 mm
  • Plate thickness: 6 mm to 60 mm
  • Length: Up to 12000 mm without welding joint (can be made longer with welding joint)
