Sourcing & certs

Rack, sourced, or yours

Three ways material lands on the machine — all with the same paperwork trail.

Off the rack

Six families, nested same-day. Heat numbers tracked from rack to nest to your delivery note.

Same-day nesting No minimum order
Sourced per job

Common specialty in 2–4 days, imported plate in 1–3 weeks. The date is firm on the quote.

3.1 certs attached MOQ flagged up front
Your material

Bring your own sheet or tube. We inspect it on arrival, log the cert, and cut on the same terms.

Incoming inspection Offcuts returned on request
EN 10204 3.1 mill certificates on request — heat numbers follow every nest, whether the sheet is ours or yours. HOW QUOTING WORKS →

Not sure which grade to spec?

Send the drawing and what the part has to survive — we'll match the grade, or price the nearest stock material both ways.
