01 Cold rolling & tube mills

Everything downstream depends on the coil

We cold roll our own coil and run it straight into the tube mills. Controlling the input is what lets us hold gauge on the output — through pipe, section, profile and wire alike.

Capability

A cold-roll house that happens to make tube

Most tube mills buy their coil. We roll it. That single difference runs through everything else on this site: gauge tolerance, surface finish and forming behaviour are settled before the strip reaches a mill, not corrected afterwards.

How it is made

From coil to consignment

Six stages, every one of them inspected. Nothing leaves the mill without a certificate against the standard it was ordered to.

  1. 01

    Coil in, inspected

    Prime soft mild steel coil is checked for gauge, width and surface before it is accepted onto the floor.

  2. 02

    Slit to width

    Coil is slit to the strip width the finished section calls for, so wall thickness lands on tolerance.

  3. 03

    Formed and ERW welded

    Strip is roll-formed and high-frequency welded into round, square or rectangular section on automatic lines.

  4. 04

    Sized, straightened, cut

    Tube is sized to final outside diameter, straightened, and cut to length. Ends are faced and deburred.

  5. 05

    Galvanized or finished

    GI lines go through hot-dip galvanizing and threading to BS EN 10226. Black pipe is finished and coated.

  6. 06

    Tested and certified

    Hydro test, dimensional check and weight check. Mill test certificate issued with the consignment.
