Ruukki double grade S420MH / S355J2H is a structural hollow section that meets the requirements of standard EN 10219. It combines the high strength of grade S420MH and the excellent usability of grade S355J2H. By designing the structure using grade S420MH, considerable weight reduction can be achieved and longer spans can be used in structures. Ruukki double grade replaces S355J2H as a stock grade and is suitable for all the S355J2H and S420MH applications.
