方管市场价格弱势运行。主导市场，北京、天津、上海、广州均出现下跌。随着期螺夜盘的走低，市场观望情绪转浓，不过下游需求依旧较 弱，因此周末市场表现普遍低迷。今早开盘，期螺震荡向下后维持低位平稳运行，期螺走势对市场没有任何提振，同时也没有大的利好进入市场，所以今日市场价格 弱势运行。从市场了解到，今日各地市场成交普遍低迷，京津冀地区受大雨天气影响，整体出货较差，北京方管10家大户出货量合计0.5万吨，比周五少了 0.25万吨；杭州地区午后再降20，主流报价至3910，市场反馈成交偏弱；广州市场反馈同样不佳，近期市场也没什么投机需求，不过方管厂家情绪较为平和。 整体看来，今日各地成交不佳，期螺走低，钢坯尾盘也降了20，故预计明日市场行情或弱势调整。
