FAQ

The operation of the steel industry in the first two months was divided 2024-04-11 15:14:23.225

Crude steel consumption will fall by 2.8% in 2023. The continued decline in real estate will continue to weaken the role of driving steel demand. Although demand for infrastructure and manufacturing has increased, it is subject to high production capacity and terminal construction is lower than expected, suppressing the trend of steel prices. .

Data: National strip steel inventories continue to decrease 2024-04-11 15:11:18.970

The total sample inventory of hot-rolled strip steel in major markets across the country is 1.0917 million tons, a decrease of 117,900 tons from last week, a decrease of 157,400 tons from the same period last month, and an increase of 287,100 tons from the same period last year.

National shipbuilding completion volume increased by 95.4% year-on-year 2024-04-11 15:09:11.042

The industry predicts that the demand for ship steel will increase by 4.8% year-on-year in 2024, which is smaller than the growth rate in 2023. The volume of new orders may not be as high as in 2023, and the growth rate of related steel demand will fall back. The overseas shipping market has further tightened its green and environmental protection requirements, which will have a certain impact on the quantity and structure of shipbuilding steel.
