Recently, SMM tracking the market found that some areas, such as Shaanxi, Jiangsu, Zhejiang and other markets, as well as the second and third line resources thread price difference slightly expanded compared with the normal period last year. In addition to the rising operating rate of electric arc furnace steel plants, the supply of second and third line resources can be supplemented, the construction pace of small and medium-sized housing construction projects is slower than that of infrastructure and other industries is also one of the important reasons. It is reported that under the policy support of the current infrastructure projects, the construction rhythm has basically returned to normal, and there is even a release of demand for rush work. At the same time, most housing construction enterprises still say that the current personnel is not yet fully in place, and the shortage of funds is more prominent, dragging down the progress of construction, it will take time to return to the normal level. Follow up on this week's SMM terminal requirements report. As far as the later stage is concerned, under the recovery of blast furnace plant production, the steel price may continue to be in a weak adjustment state in the short term, and the price difference between the first line and the second and third line resources will also be gradually recovered with the recovery of housing construction demand.
