Limits
S355J2H when it is structural hollow section. E470 when strength needs to go further up.
Delivery
We source E355 from European mill partners as plate, flat bar, round bar, seamless tube, welded tube, 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
E355 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.
