Since the outbreak of the public health event, domestic enterprises, particularly downstream engineering companies, have delayed their resumption of work after the holiday this year. In response, relevant departments have introduced targeted policies and measures to help businesses resume operations. As of today, the resumption rate of industrial enterprises with a certain scale in 27 provinces and cities has reached 90%. It is learned that the national pipe market was extremely weak in February, with daily transactions of only a few tons. After March, as downstream enterprises resumed operations in an orderly manner, demand stabilized and improved slightly, leading to a gradual increase in pipe sales. Lead rod inventory began to decline in early April, and traders' pressure has been gradually easing. This public health event has had unpredictable impacts on the price, inventory, demand, and transactions of pipes. However, this impact is only short-term. With the various economic stimulus policies implemented in China, the domestic river景观栏杆 market will eventually recover to its previous prosperity.
