7日國內方管價格普遍上漲。今日早盤，原料鋼坯價格一再拉漲，受此氛圍帶動，加之期盤的高開高走，國內方管價格明顯跟漲，尤其河北地區管廠出廠價格盤中再次出現二次追漲的局面，由于價格拉漲過快，管廠反應出貨一般，但較昨日有好轉，現河北地區主流管廠方管4寸(3.75mm)出廠報價在4340-4460元之間，累漲40-50元。下游市場，今日大部分地區方管報價有明顯跟漲動作，但貿易商普遍反應終端需求依然偏弱，高價位成交困難，不少地區出現倒掛現象，因此操作起來更加謹慎，目前貿易商庫存依然不高。總的來看，受環保因素以及原料繼續趨緊影響，近期方管價格仍易漲難跌，但由于拉漲幅度較大，短期警惕回調風險。The price of domestic square tube rose in 7 days.
