Shipbuilding and Offshore platform 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. 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.
