    03

    Mechanical properties

    Yield, tensile and elongation are confirmed against the minimums for the product form.

    04

    Testing & PMI

    Hydro or NDT, IGC where specified, and positive material identification on request.

    05

    Release & traceability

    The heat number on every piece matches the certificate. 3.2 with your inspector on request.

    Straight answers

    The six questions every buyer asks first.

    BuyerWhat does Bright Tubes supply?

    Bright Tubes

    Stainless steel, nickel alloys, carbon and alloy steel, wear plate and non-ferrous metals in 104 grades, as pipe, tube, plate, sheet, coil, bar, fittings, flanges, structural sections, gratings, rails and fasteners.

    BuyerIs it from stock or made to order?

    Bright Tubes

    Both. Common grades and sizes ship from our own production and ready stock; everything else is sourced from approved mills to your specification.

    BuyerWhich certificate will I get?

    Bright Tubes

    An EN 10204 3.1 mill test certificate with heat-number traceability as standard. 3.2 with your third-party inspector, and IBR documentation, on request.

    BuyerCan you arrange PMI and third-party inspection?

    Bright Tubes

    Yes. PMI by XRF or OES, dimensional checks and inspection by your nominated agency before dispatch.

    BuyerWhere do you ship?

    Bright Tubes

    The GCC, Southeast Asia, Europe and the UK, the USA, Canada, Australia and across India, packed and documented for the destination.

    BuyerWhat should my enquiry include?

    Bright Tubes

    Grade and specification, form, size, quantity, tests, certificate type and destination. A BOM or spreadsheet in any format is fine.
