Serial weldments, welded, machined and NDT-documented, one contract

You send a drawing. You receive a weldment machined after welding, with material certificates, the dimensional report and the NDT protocol, under one PO. In-house to 10 t per EN ISO 3834-2. To 64 t x 45 m via a certified partner under EN 1090-2 EXC2. Stratosteel owns the outcome.
