Steel that a turbine sits in

A hydro unit needs heavy, accurate steel around it: the pit it turns in, the plates the stator is set on, and the bracket that carries the bearing.

Pit liner

Plate rolled to the pit radius, with anchor ribs welded on the outside so it locks into the concrete.

How is it possible at Allmarc?

Sole plates

Thick plates machined flat and drilled for their anchor bolts, set level before the stator goes in.

How is it possible at Allmarc?
Kotec newRun10DX CNC beam drilling line in the Allmarc works

Used here for: Sole plates

Heavy profiles that need precise holes, where plasma cannot do the job: the lower structure and panel borders of a ground flare, and every bolted PEB and multi-storey frame.

  • H-beams up to 1,000 x 500 mm
  • Drills 3 faces in one pass
  • Channels, angles and box sections
All our machinery

Upper bracket

A hub with radial arms, built up from plate and welded in a fixture, then jacked against the pit wall on site.

How is it possible at Allmarc?

In 2024 we were the only buyer of Deratech’s 20 kW, 12 m laser.

  • 20 kW
  • 12 x 3 m bed
  • Pallet changer
All our machinery

Used here for: Upper bracket

Tapered rafters and other non-uniform built-up sections, welded faster and with deeper penetration.

  • 40 m, state of the art
  • No programming: weld lines taken from the 3D model
  • Tandem torch: two wires at once
All our machinery

05 / 06

Columns and crane girders

Built-up columns with crane brackets, and plate girders with stiffeners, rails and end stops, cut and drilled on the beam lines.

How is it possible at Allmarc?

Used here for: Columns and crane girders

  • Plates matched and tack-welded
  • Automatic feed and stitch welding
  • H and I sections built from plate
