Hull plate -- Shanghai Royal Industry

KR Grade A steel is a kind of high tensile strength marine steel. All of these steels have been engineered to be optimal long-lived shipbuilding steels.KR Grade A Shipbuilding steel plates are mainly used for making the offshore oil drilling platform, the hull of ship building and ship repairing, the platform pipe joints and other components. All the KR Grade A shipbuilding Steel offered by Shanghai Royal Industry can be certificated by Shanghai Royal Industry as per customer's request.
