Manufacturers of heavy steel structures, stacks, ducts and plate girders

Manufacturing Facility & Machinery

Five acres at Rajgangpur, two 96 m bays under 20 MT cranes, an automated H-beam line and an in-house blasting and painting booth.

Land & Infrastructure

Built for Long, Heavy Pieces

Both bays run 96 metres end to end under 20 MT cranes, so stack shells and girders move from cutting bed to paint booth without leaving the hook. We keep adding machines as orders demand.

  • Site area 5 acres
  • Covered shed 44,000 sq ft
  • Bays 2 × 17 × 96 m
  • EOT cranes 2 × 20 MT, 1 × 5 MT
  • Mobile cranes 2 × 12 MT
  • CNC profile cutting 4 × 15 m
  • Hydraulic press 600 MT
  • Plate rolling 25 × 2,500 mm
  • SAW welding 1,000 + 1,250 A
  • MIG / ARC sets 17 / 21
  • CNC drilling Ø40 mm
  • Power / DG 200 / 125 kVA

H-beam and built-up section line

For H-beams and built-up sections we run a complete line: CNC plasma and flame cutting of flanges and webs, an automated beam assembly machine (up to 2 m deep and 1 m wide), submerged-arc welding, and a hydraulic straightening machine that corrects flange distortion up to 80 mm thick. The same line feeds boiler structures and auto-weld beams and plate girders.

Plate forming

A plate bending (rolling) machine takes plate up to 25 mm thick and 2,500 mm wide for stack shells, casings and cylindrical tanks, and a 600 MT hydraulic press handles pressing and forming work.

Blasting and painting

Surface preparation and coating are done in-house, so pieces leave the works ready for erection.

  • Blasting booth 12 × 6 × 5 m, Kulmech blasting hopper
  • 40 HP ELGI screw compressor at 7.5 kg/cm²; 8–10 mm nozzles at 7 kg/cm²
  • Media: sand, copper slag, shot and grit
  • Airless spray for paints up to 60% volume solids, pneumatic paint stirrer, and conventional spray on a 3 HP compressor

Coating checks at this stage are listed under quality and inspection.
