The moody interior of a steel mill with heavy fabrication machinery
// SERVICES

Eight disciplines, one chain.

From the first cut to the final lift, DSG holds every step in-house — so quality, sequencing and accountability never cross a vendor boundary.

01Clean profiles, zero rework

CNC Plasma & Laser Cutting

High-definition CNC plasma, fibre-laser and oxy-fuel cutting for plate and section. Nested for material yield, edge-prepped for welding, and dimensionally verified before anything leaves the cutting bay.

  • HD plasma up to 60 mm mild steel
  • Fibre laser for fine-tolerance thin gauge
  • Oxy-fuel for heavy plate & bevels
  • Automated nesting for material yield
  • Weld-ready edge preparation

02Tight radii, repeatable bends

Bending, Forming & Rolling

CNC press-brake forming, plate rolling and section bending across a wide tonnage range. Programmed back-gauges and tooling libraries keep multi-bend parts consistent across the run.

  • CNC press brakes to 400 tonne
  • Plate rolling to 40 mm
  • Section & angle rolling
  • Multi-bend programmed back-gauge
  • Forming dies for repeat profiles

03Qualified procedures, traceable welds

MIG / TIG / SMAW / FCAW Welding

Coded welding to AWS D1.1 and ISO 3834-2 across MIG, TIG, stick and flux-cored processes. Every joint runs to a qualified WPS, welded by certified welders, and logged for full traceability.

  • MIG / MAG (GMAW) for production volume
  • TIG (GTAW) for stainless & precision
  • SMAW & FCAW for heavy structural
  • Qualified WPS / PQR for every joint
  • Certified welders, weld-map traceability

04Precision where it counts

CNC Machining

CNC milling, turning and drilling for machined details, base plates, connections and bespoke components — finishing fabricated assemblies to fit-up tolerance.

  • CNC milling & turning
  • Drilling, tapping & boring
  • Machined base & connection plates
  • Bespoke component runs
  • Fit-up to assembly tolerance

Design & Engineering

In-house CAD, 3D modelling and connection design. We take your GA drawings to fabrication-ready shop details, with clash-checked models and an approval trail before steel is cut.

  • Structural detailing & shop drawings
  • 3D modelling (Tekla / Advance Steel)
  • Connection design & calculations
  • Clash detection & coordination
  • Approval & revision control

Erection & Installation

Site erection by our own rigging crews — survey, setting-out, lifting, bolting, site welding and handover — closing the loop from drawing board to standing structure.

  • Method statements & lift plans
  • Survey & setting-out
  • Crane lifts & rigging
  • Site bolting & welding
  • Safety-led, on-time handover
