From the ship plate to our building materials, steel plate is needed everywhere in our daily life. The quality of A514 Gr E structural steel material, steel plate is also related to each of us. Therefore, the quality of steel plate should be strictly controlled from manufacturer to the user. Once there are quality problems with steel plate, it is very easy to generate major events endangering people's lives.
According to the latest data released by the world iron and Steel Association, in March 2020, the crude steel production of 64 countries and regions included in the statistics of the organization totaled 147 million tons, down 6.4% year-on-year. In the first quarter, the A514 Gr E structural steel material, global crude steel production reached 442 million tons, down 1.3% year-on-year. Because of the new crown epidemic, factories in Europe, the United States and other places were shut down, Global steel production outside China fell the most since the financial crisis.
