02About us

What we do sounds simple: we take flat steel and turn it into tube and profile. Between the two lies stand after forming stand, one continuous weld, and a precision measured in millimetres.

03Process

Six stations,one length of steel.

Steel coils stacked in the hall
Coil · ST37 / ST52

Coil

Steel arrives as coil. Thickness and grade are checked before it is allowed onto the line.

Rollers and knives of the slitting machine
Slitting · width = perimeter

Slitting

Rotary knives cut the coil into strips of exact width — the width of each strip is the perimeter of the finished profile.

A row of forming stands on the tube line
Roll forming · stand by stand

Forming

The strip runs through a row of forming rolls, bending a little more at every stand until its edges meet.

The welding station spraying coolant
Seam welding · cooling

Welding

The edges are welded in an instant, and coolant floods the fresh seam.

The yellow flying saw on the line
Flying saw · cut to length

Cutting

The flying saw travels with the tube and cuts it to length without stopping the line.

Strapped bundles of square hollow section in the store, beside slit strip coils
Bundling · ready to ship

Bundling

Lengths are counted, bundled and strapped, then wait in the store for loading.
