Steel for shipbuilding A32 D32 E32 A36 D36 E36
Shipbuilding steel plate A32 D32 E32 A36 D36 E36 contains two kinds as common strength and high strength ship plate according to different yield and tensile strength.Common strength shipbuilding plate are mainly used to contribute hull of ship,and high strength shipbuilding plate are mainly built the cranes of bulk and breaker ships in low temperature surroundings.
we can also do the nc cutting and deep processing according to users' requirements, and provide standard production of steel according to the national standards of metallurgical industry standard and the enterprise internal control standard etc. There are other steel types: carbon structural steel sheet, boiler plate, pressure vessel board, low alloy steel, alloy steel, mould plate, high-rise building steel, steel, petroleum shipbuilding platforms conveying pipeline steel plate, bridge steel sheets and shipbuilding steel.In addition,according to the customers' requests,we can provide various special specifications and special weight of steel A32 D32 E32 A36 D36 E36.
