BBN Steel offers grades that are certified by ABS (American Bureau of Shipbuilding) and represents the Higher Strength Group of ABS steel plate grades AH36, DH36 and EH36. Like ABS steel plate grade A & grade B, these grades of steel plate are almost exclusively utilized in the shipbuilding industry for the construction of structural parts of ships, barges and marine equipment.
