Price stability of galvanized square tube in Guiyang market. Today, rebar futures high shock operation, Tangshan billet prices rose slightly. However, the opening price of Guiyang market is stable. The main reason is that the market demand has not been fully released in the near future. The daily order volume of Qianlang, gaimao and 8km freight yards is less than 5000 tons, and the confidence of square tube manufacturers is insufficient. There are many low-level transactions in the market. However, the price of raw materials is strong, and the attitude of square tube manufacturers is strong. At the same time, the total amount of inventory is still at a low level in the same period of previous years, the amount of arrival has not increased significantly, and the inventory pressure of square tube manufacturers is small. Comprehensive consideration, the price of galvanized square tube in Guiyang market may be stronger in a short time.

In terms of square tube price, Shuigang now has 4950 yuan for Φ 8-10mm small-diameter square tube, 4890 yuan for Φ 8-10mm high-speed wire and 4780 yuan for Φ 18-22mm large-diameter square tube, which is the same as yesterday.
