High toughness steel marine plate shipbuilding steel plates
The ship building steel (Hull structural steel) is divided to normal strength and high strength structural steel according to strength grade. Ship plate is a kind of hot rolled steel plate and produced for making hull structure according to the constructions rules of the Classification Society. The normal strength structural steel has four quality grades as A,B,D,E according to the classification society standard rules and the high strength structural steel has three strength grades and four quality grades.
The ship plate has been widely used in ship building, construction, light industry, household appliance, automobile, ocean projects, boatyard, dock facilities, etc.
