DNV GL grade B bulb flat steel is general strength steel for shipbuilding constructions. The bulb flat steel requires the correspond ship classification to the shipbuilding plates. For the same reason, DNV GL grade B bulb flat steel corresponds to DNV GL grade B ship plate.
In recent years, with the rapid development of the shipbuilding industry, the demand for DNV GL grade B bulb flat steel and so on marine bulb flat steel is strong. Generally, larger ships and regular ships are mostly designed with marine bulb flat steel such as DNV GL grade B bulb flat steel. The DNV GL grade B bulb flat steel of the same thickness as the connected DNV GL grade B bulb flat steels is used as the aggregate, which is also called bone or keel.
Compared to DNV GL grade B angle steel or DNV GL grade B flat bar, DNV GL grade B bulb flat steel is stronger in terms of strength to weight ratio and are excellent for stiffeners for ship and barge building.
GB T 5312 Carbon and carbon-manganese steel seamless steel tubes and pipes are mainly for ship use, also known as shipbuilding steel pipes. Under GB T 5312, there are mainly 5 steel grades: grade 320, 360, 410, 460 and 490. Each grade covers three levels: I, II, III.
Angle steel, commonly known as angle iron, is a long strip of steel whose sides are perpendicular to each other. There are equal angle steels and unequal angle steels. The two sides of equal angle steel are equal in width. The unequal angle steel is also known as L shape profile steel.
Flat bar steel can be produced according to the user's needs, with fixed thickness, width and length. It can reduce the cutting process for users, reduce the consumption of labor and materials, and also reduce the processing loss of raw materials.
Bulb flat steel for shipbuilding
The bulb flat steel is a kind of medium section material which is mainly used in the field of shipbuilding and bridge building, and the shipbuilding bulb flat steel is an auxiliary medium section material for shipbuilding.
