LR, ABS, NK, GL, DNV, BV, KR, RINA, CCS Grade A Shipbuilding steel plate

Capable Classification Society Quality Authentication from LR, ABS, NK, GL, DNV, BV, KR, RINA, CCS，Grade A steel plate is used for shipbuiling s hull structure and platform. The shipbuilding steel plate grade A is the common tensile strength steel. It has good toughness properties and higher strength, strong corrosion-resistance,the processing properties,and welding properties.ASTM A131 Grade A steel plate can be used in the manufacture of the ship s hull structure whose weight is below 10000 tons,and usually do navigation around coastal and river area.

Grade A shipbuiling steel plate specification:
Thickness: 4mm to 260mm,
Width: 1200mm to 4000mm
Length: 3000mm to 18000mm.
