In most parts of China, the prices of steel pipes such as square pipes and rectangular pipes have been pushed down by inertia. Under the influence of leading steel mills to reduce the ex-factory price, the spot market prices in various places are competing to lower, constantly refreshing the lowest price. In terms of market transactions, due to the influence of dock sites and wood processing plants, steel pipe transactions are weak, demand is reduced, and market purchases are low. However, near the Qingming holiday, some manufacturers have a certain stocking demand for pipes, and the overall turnover increased slightly compared with yesterday. Recently, bad news has been concentrated, the futures market has fallen sharply, spot trading has been sluggish, and market pessimism has increased. It is expected that the domestic steel pipe market such as square pipe will continue to run weakly in the short term.
