Weldable structural steel
S355J0WP / 1.8945 non-alloy structural steel
S355J0WP is weathering structural steel to EN 10025-5. WP forms a dense patina outdoors. Trade names such as Corten typically point here — the certificate carries the EN designation.

Limits
S355J2 when it is to be painted and welded as ordinary structural steel. Confirm WP on the certificate.
Delivery
We source S355J0WP from European mill partners as plate, flat bar, round bar, cut to your dimensions and ship the certificate with the material. Typical condition: +AR or +N. From a single cut piece to larger lots — with no minimum charge, so you do not have to buy a full commercial length to get what you need.
Certificates and documentation
S355J0WP can be supplied with a material certificate to EN 10204, depending on producer, dimension and the requirements specified for the delivery. On welded structures it is the analysis, the strength class and — where the standard requires it — the impact toughness that the certificate must show. EN 10204 3.1 can be supplied on a wide range of our materials, and 3.2 is ordered when the project requires third party.
