贵阳方管市场价格维稳出货为主，市场成交转弱。今日贵阳工角槽钢价格维稳运行，原材料方面现昌黎普碳方坯含税出厂3470元/吨降20元；今日期螺宽幅震荡运行。今日唐山丰润区发布落实8月份 大气污染管控要求的通知，当地型钢轧钢厂16日零时开始落实停产政策，目前方管库存处于低位状态，市场降价空间不大。从需求面来看，昨日发布的经济数据显 示，房地产开工投资继续下滑，基建投资也未彰显“补短板”功能，数据的弱化一定程度上削弱了市场对下游需求的预期，方管厂家操作谨慎出货为主，故价格短期内难 有大幅调整的空间。综上所述，预计明日贵阳地区方管价格震荡偏弱运行。

Guiyang is mainly responsible for maintaining stable market prices and delivering goods, while the market turnover is weak. Today, Guiyang Gongjiao channel steel prices maintain stable operation, raw materials are now Changli Pu carbon billet with a tax of 3470 yuan per ton, down 20 yuan; today's snail wide vibration operation. Today, Fengrun District of Tangshan issued a notice to implement the requirements of air pollution control in August. The local section steel rolling mill began to implement the stop-production policy at 0:00 on 16th. At present, square tube stocks are in a low position and there is little room for market price reduction. From the demand side, the economic data released yesterday show that real estate start-up investment continues to decline, infrastructure investment has not shown the function of "make-up board". The weakening of data weakens market expectations of downstream demand to a certain extent, and manufacturers are mainly cautious in handling shipments. Therefore, it is difficult for prices to adjust substantially in the short term. 。 In summary, it is expected that the price fluctuation of local government in Guiyang will be weak tomorrow. 方管价格方面：截止发稿，唐山5#角钢价格在4520元/吨；唐山16#槽钢价格在4520元/吨；日照20#工字钢价格在4570元/吨。
