AH36 shipbuilding steel plate through the quality certification
AH36 steel is a kind of high tensile strength steel for shipbuilding. Our AH36 shipbuilding steel plates are certified by Lloyds Register of Shipping, but a number are also classified by DNV.
Size range of AH36 shipbuilding steel plate:
Thickness: 5 – 150 mm
Widths: 1500 – 3000mm
Lengths: 6m, 12m and 14m, or according to customers’ requirement
