■ Overview
The higher steel grade DNV Grade FH40 shipbuilding steel plate are used abnormally owning to its high cost and substitutability.For shipbuilding steel plate DNV Grade FH40,the standard rolling size is width of 2000mm and length 6000mm,considering the steel plates can be loaded into the twenty feet container,we suggest the end users to accept 5800mm,it would cost much ocean freight for them when transport.International purchase sizes always follow the feet sizes,after calculation,the most demands sizes for DNV Grade FH40 ship plates are normally 2438mm*9144mm or 1829mm*6096mm.
