Limits as specified in AS/NZS 3678. Where the standard sets different values by thickness or product analysis, each band is shown separately.
AS3678-250 is normally specified for industrial and commercial building structures, crane booms, machine frames, and general welded fabrication.
We supply it cut to size by plasma, laser or waterjet, with edges machined or flame-cut to your drawing, and can deliver in the heat-treatment condition your fabrication procedure requires.
As-rolled, normalized, normalized rolled or thermomechanically rolled (TMCP), following the delivery condition coded in the grade designation.
Z15 / Z25 / Z35 to EN 10164 on request; UT to EN 10160; EN 10204 3.1 / 3.2 mill test certificate; Third-party inspection by SGS / BV / TÜV
Seaworthy packing — bottom skids, steel strapping, VCI film and edge protection — is standard for sea freight. Container loading plans with piece weights are issued before shipment.
Send the grade or the standard you specify, the thickness range, quantity and destination port. We reply with price, lead time, delivery term and the applicable certificate within 12 hours (Mon–Sat, GMT+8).
