本周天津方管市场价格下调， 成交惨淡。近一段时 间以来，国内大部分地区冷轧市场价格普遍下调，尤其以北京、天津、上海等地价格下调比较明显，其中天津本地价格较上周同期下调100元，究其根本，是因为 终端需求因中美贸易战影响萎靡不振，加工、家电、汽车等行业拿货多以刚需为主，观望情绪比较严重，加之近几日黑色系期货跳水情况明显，下游用户操作愈发谨 慎，问及商家如何看点后市发展，多认为在4、5月份资源消化完成之前价格还会有下调可能，6月份应该稳健操作，少量订货为主，综上所述，如无重大利好，下 周本地冷轧价格仍有下调的可能性，预计下调30-50元左右，还请广大方管厂家谨慎操作，理性看待。

This week, Tianjin Fangguan's market price was lowered, resulting in poor turnover. In recent years, the price of cold rolling market in most parts of China has been generally lowered, especially in Beijing, Tianjin and Shanghai. The local price of Tianjin has been lowered by 100 yuan compared with the same period last week. The reason is that the terminal demand is depressed due to the impact of Sino-US trade war. The processing, household appliances, automobile and other industries mainly take goods just in need and wait-and-see mood. More serious, in addition to the black futures dive in recent days, the downstream users are more cautious in their operation. Asked how the merchants look at the future development, they mostly think that the price will be reduced before the completion of resource digestion in April and May. In June, they should operate steadily, with a small number of orders as the main factor. In summary, if there is no significant advantage, the local cold rolling price will still be reduced next week. Sex is expected to be reduced by about 30-50 yuan. We also invite the majority of managers to operate cautiously and rationally.
