S355JO steel stockholders and suppliers, delivering to the whole of the India. We are suppliers of S355 grades in steel plate, round bar and flat bar.

As an unalloyed low carbon steel grade S355JO is supplied in the hot rolled and cold drawn conditions. The S355 steel specifications are high yield non alloy steels. First specified in the European EN10025 standard and later published by the British Standards Institute (BSI). These standards superseded the BS4360 grades. The average minimum yield for this material is 355 N/mm², hence the name S355 (with the 'S' giving reference to it being a structural steel).
