周末至今，國內方管價格再現普漲。周末，隨著無錫地區環保限產政策的再次升級，由現有的部分燜爐限產全部提高到凡減產必停爐，不得以燜代停，受此消息帶動，鋼市價格被不斷推高。方管方面，受成本端的有力支撐，現河北地區主流管廠方管4寸(3.75mm)出廠報價在4390-4550元之間，比上 周五上漲30-60元不等，目前管廠倒掛情況有所好轉，但由于價格處于高位，整體成交一般。下游市場，周初開市大部分地區大幅跟漲，但據貿易商反饋出貨不暢，市場恐高情緒較濃。短期來看，因環保限產帶來的炒作空間依然存在，原料價格堅挺將繼續影響國內方管價格高位運行，但整體操作更趨謹慎。Up to the end of the weekend, the price of domestic square tubes has increased. Over the weekend, with the renewed upgrade of environmental protection and production restriction policy in Wuxi area, the existing partial stove production restriction has been raised to the point that the stove must be stopped if the production is reduced, and the stove must not be replaced by the stove. Driven by this news, the steel market price has been continuously pushed up. In terms of square management, supported by the strong cost side, the 4-inch (3.75 mm) ex-factory price of Hebei mainstream pipe factory is between 4390-4550 yuan, up 30-60 yuan from last Friday. At present, the inverted situation of pipe factory has improved, but due to the high price, the overall transaction is general. In the downstream market, most of the market opened early in the week with a sharp rise, but according to traders feedback shipment is not smooth, the market is afraid of heightened sentiment. In the short term, there is still room for speculation due to environmental restrictions. Strong raw material prices will continue to affect the high domestic square tube prices, but the overall operation is more cautious.價格方面：國內重點城市4寸(3.75mm)方管的平均價格為4573元，比上周五上漲 45元，各中心城市價格均有不同程度的上漲，其中無錫漲60元、無錫漲50元、北京漲50元、西安漲60元、武漢漲30元、沈陽漲80元、上海漲30元、 濟南漲40元、廣州漲30元、成都漲20元。Price: The average price of 4-inch (3.75 mm) square pipe in key cities in China is 4573 yuan, up 45 yuan from last Friday.
