1. Introduction of S355G10+N steel plate:
S355G10+N steel plate belongs to weldable structural steel for fixed coastal structures. It is European grade, and its delivery state is normalized or normalized rolled, impacte at -40°C, and 10 after G represents the relevant figures of the characteristics of the steel grade. The +N behind it means normalizing or normalizing rolling.
2. S355G10+N steel plate implementation technical standard: EN10225-2009.

5. Application of S355G10+N steel plate:
The marine engineering steel is suitable for various complex working conditions and harsh natural environment, and the service period is 50% higher than that of the ordinary ship steel. S355G10+N steel plate is suitable for the manufacture of structural parts such as offshore and offshore oil production platforms and terminal equipment.
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.
