Ship plate refers to the hot-rolled steel plate produced according to the requirements of classification society for the manufacture of ship structure. The general strength structural steel according to the China Classification Society code is divided into four quality grades: A, B, D and E (CCSA, CCSB, CCSD and CCSE). China Classification Society code standard high strength structural steel has three strength grades and four quality grades.

Application
|
Widely used in a variety of architectural and engineering structures,such as
1.) metal constructions such as buildings,bridges,ships; 2.) transmission tower, reaction tower; 3.) lifting transportation machinery; |
Due to the harsh working environment of the ship, the hull shell is subject to chemical corrosion of seawater, electrochemical corrosion and corrosion of marine organisms and microorganisms; the hull is subjected to large wind and wave impacts and alternating loads; the shape of the ship is complicated by processing methods, etc. Steel for hull structure is strictly required. First of all, good toughness is the most critical requirement. In addition, high strength, good corrosion resistance, weldability, forming properties and surface quality are required.

Cutting large steel plates as your requirements to make the surface of the plate bright by miling and grinding, also can make holes and make angle degrees,and can weld by your drawing. For the thickness under 30mm, cutting by laser; For thickness over 30mm, mainly OXY-cut, flame cutting. For the thickness 200mm steel plate, because during the flame cutting, the temperature is very high, so the cutting parts steel plate might be broken at the angle part, then our workers will repair the angles to be good condition.
