How we do it

Folding turns a flat blank into a bracket, a tray, a cover or a cladding rail. The brake does the forming, but the accuracy comes from the flat pattern: we develop every part from your model using the bend allowance for the material and tooling we will actually use.

The first part off every batch is measured before the rest are run. Mild steel from two different casts, both certified S275, can come off the same die at angles a degree apart, so we correct on the machine rather than trusting the table.

Parts longer than the 3.2-metre bed are formed in sections, joggled and welded to length in the next bay, then dressed so the joint disappears under the finish.

Included as standard

  • Flat patterns developed from your 3D model
  • Bend allowance set for your material, not a table
  • First-off inspection report on request
  • Longer parts joggled and welded to length

Questions about bending

Why does my bend angle need a tolerance?

Steel springs back when the ram lifts, and how far depends on the actual yield of the plate, not the grade on the certificate. We measure the first part and correct, but ±0.5° is the honest promise.

What is the smallest flange you can fold?

About four times the material thickness plus the tooling radius. We will tell you at the quote stage if a flange is too short.
