S355JR steel is a more yield and tensile strength steel grade than S235JR and S275JR. it is used to be in in riveted, bolted, or welded construction of bridges and buildings.
BBN Steel is specialized in supply S355JR steel grade. If you need more low temperature impact test, you could choose S355J0 or S355J2 Which has a 0 or -20 degree impact test.
