Fabrication Welding

Banding bars and attachments are welded with minimum 3mm fillet welds to one side of:

  • every 5th load bar on A & B Pattern grating
  • every 4th load bar on C & D Pattern grating
  • every 3rd load bar on F Pattern grating

Other welding is applied to cut-outs, splays or circles as appropriate or as requested.

Pipe Sizes

The tolerances for pipes will depend on the pipe specification that is used.
  1. Variations in cross section
    Specified OD up to 50mm +/- 0.2mm
    Over 50mm OD to 75mm +/- 0.25mm
  2. Variations in thickness +/- 10%

Base Plates

All dimensions +/- 1mm
Thickness +/- 0.2mm

Sphere Drilling

Drilled diameters 2 to 4mm oversize
Hole Angle +/- 1º in any direction (any 2 axis)
All stanchiones (except AM) +/- 0.5º in the slope direction only
