The selection principle of steel plate for high-rise building is: it can not only make the structure safe and reliable, but also can save steel and reduce the cost. Different use conditions should have different quality requirements. In terms of the mechanical properties of steel such as a573 gr.65 structural quality carbon plate, yield point, tensile strength, elongation, cold bending property, impact toughness etc. are the indicators to measure the quality of steel. In the design of steel structure, the appropriate steel should be selected according to the characteristics of the structure. The selection of steel is not only an economic problem, but also related to the safety and service life of the structure.

For the estimation in April and the second quarter, the estimation on March 16 is still valid, but the decrease in April is 10% higher than the neutral prediction. It is a conservative estimation based on 10% for the high probability event. In the second quarter, the output of overseas pig iron will be reduced by 11.67 million tons, affecting the demand for a573 gr.65 structural quality carbon plate iron ore of about 1.84 million tons; in the first half of the year, the output will be reduced by 18.899 million tons, affecting the demand for iron ore of 32.13 million tons.

In October, the demand for finished products improved significantly, breaking through the high of 4.4 million tons per week, and the price of black products went up overall. Among them, coke performed particularly well under the stimulus of downstream shortages and high molten iron output. It wasn't until early November that coke futures prices fell from a high level due to high disk premiums. After six rounds of increases, the spot price also began to weaken. Downstream steel mills were more resistant to the seventh round of increases.
