Firstly, the thickness of the shipbuilding steel plate is thicker and the accuracy is better than that of the general steel plate, otherwise it will be easily impacted by the sea water, which will bring life danger to the people on board.
Secondly, the difference between the shipbuilding steel plate and the ordinary steel plate is more corrosion-resistant. The ship has been soaked in seawater for a long time. If it does not have good corrosion resistance, the steel plate will easily rust, and the weight of the ship will be reduced. It will become larger, and it will also pollute the sea water and cause ecological damage.
Third, the wind and wave resistance is better. Strong winds and waves are often encountered in the ocean. If the performance of the shipbuilding steel plate itself is not excellent and not outstanding, it is easy to be damaged by strong winds and waves.
Fourth, the service life is longer, because the excellent properties of the shipbuilding steel plate make the ship board can be used for a long time, and some old ships can dismantle the ship board and reuse it.
Fifth, the price of shipbuilding steel plate is higher than that of ordinary steel plates, the thickness and strength are higher, and the processing steps are more complicated, so the price will be higher.
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.
