近日国内方管市价稳中盘整运行需求量依然较少方管各地区市场价格稳中有跌，需求偏弱。近日鞍钢普碳方管出厂价出现上调，市场鞍钢资源市价趋强，临沂管厂方面，实际接单价个别管厂有小幅上调10-30元，管坯实际接单量有所增长。 虽然涨价消息满天飞但是方管市…

本周重庆市场镀锌方管明显下跌，主流成交一般。汽车板块产销持续下滑，冷轧需求一降再降，方管厂家信心严重受挫。市场方面，本周价格小幅阴跌，可是价格下调并对于下游采购积极性并未起到任何作用， 反而是买涨不买跌。钢厂方面，下月对于冷系的投放将会进一步缩量，一方面适当控制市场库存增速，另一方面则是现在现货价格与生产成本已经倒挂，生产积极性 不高。方管厂家表示订货量均有所减少，以降低后期的累库风险。综上所述，故预计短期内重庆冷轧价格仍将震荡趋弱运行为主。

This week, galvanized square tubes in Chongqing market dropped significantly and mainstream transactions were normal. The production and sales of automobile plate have been declining continuously, and the demand for cold rolling has fallen again and again. The confidence of square tube manufacturers has been seriously frustrated. On the market side, prices fell slightly this week, but the price reduction did not play any role in the enthusiasm of downstream purchasing. Instead, it was buying up rather than buying down. On the one hand, steel mills will further reduce the amount of cold system put into operation next month. On the one hand, we should properly control the growth rate of market inventory, on the other hand, spot prices and production costs are now inversely linked, and production enthusiasm is not high. Square management manufacturer said that the order volume has been reduced to reduce the risk of accumulating warehouse in the later period. In conclusion, it is expected that the price fluctuation of Chongqing cold rolling will be weakening in the short term.
