Shipbuilding steel plate refers to hot-rolled steel for the manufacture of ship structures produced in accordance with the requirements of the construction society. Often used as a special steel ordering, scheduling, sales, a ship including ship plates, steel and so on.
Classification:
The Shipbuilding steel plate can be divided into general strength structural steel and high strength structural steel according to its minimum yield point strength level.
AGICO supplies and exports 2 types of ship steel, medium strength shipbuilding plate and high strength shipbuilding plate. All steel plate product can be manufactured according to Society LR, ABS, NK, GL, DNV, BV, KR, RINA, CCS, etc.
Development
Shipbuilding requires large quantities of structural steel plate to build to ship hull. Ship steel has developed into 2 series: high strength and corrosion resistant steels for modern shipbuilding, which can reduce the ship weight as well as maintenance cost. AGICO is able to supply high strength steel plate for Large container ships construction.
Shipbuilding traditionally uses structural steel plate to fabricate ship hulls. Modern steel plates have much higher tensile strengths than their predecessors, making them much better suited to the efficient construction of large container ships. Here are the Advantages of Shipbuilding Plates High corrosion resistant steel plate is perfect steel type for oil tanks, and when used in shipbuilding, ship weight is less for the same capacity ships, fuel cost and CO2 emission can be reduced.
These shipbuilding steel can also be used for offshore structures, if you are looking for shipbuilding steel plate or offshore structure steel plate, Contact ANSON now for the latest quotation.
