成都方管市场价格先弱后强，方管市场成交一般。今日成都工角槽钢及H型钢价格维稳出货为主；期螺今日宽幅拉涨上行，原材料方面现昌黎普碳方坯含税出厂3370元/吨稳。今日早盘开市成都当地现货市场成交相对较弱，下游节前备货需求基本在前两天有所释放，现货价格高位有所松动。午后随着期货的宽幅拉涨上行对现货市场有一定的提振作用，价格止跌维 稳，但成交方面下游还是按需采购为主整体与昨日相比还是略有好转。但本周市场成交情况来看，当地下游需求有所回升，供给方面随着前期钢厂的主动叠加被动限产，社会库存整体有所下降，故随着供需关系的改善，后期行情有望稳步小幅上行。综上所诉，预计下周成都区域方管价格或小幅偏强运行。

Today, Chengdu Gongjiao channel steel and H-section steel prices maintain stable shipment mainly; the snail today widened upward, raw materials are now Changli Pu carbon billet with tax 3370 yuan per ton stable. The local spot market in Chengdu, which opened early today, is relatively weak. The demand for downstream pre-holiday stocks was released in the first two days, and the high spot prices were loosened. In the afternoon, with the broad rise of futures, the spot market has a certain boost. Prices have been stable, but the downstream of the transaction is still purchasing on demand as a whole, which is slightly better than yesterday. However, in terms of market turnover this week, local downstream demand has rebounded. With the active overlapping of previous steel mills and passive production restriction, the overall social inventory has declined.
