方管市场价格偏弱运行。主导市场，北京、天津小幅下跌，上海、广州以稳为主。昨日市场氛围冷清，方管厂家成交不佳，心态较差。不过随着夜 盘的震荡向上，市场信心略受提振，毕竟期螺低迷数日，有向上的迹象还是很值得期待。今早开盘，期螺不负众望的冲高翻红，不过整体走势不算强势，加上近期需 求依旧较弱，方管厂家心态不一，所以今日开市，市场价格偏弱运行。从市场了解到，虽然今日市场价格普遍有所松动，但市场反馈还是有部分好转的。北京小幅下跌 后，下游采购有所增多，10家大户出货量合计0.71万吨，比昨天增了0.15万；杭州、广州等地反馈出货都比昨天好一些，广州上午有个别小跌的资源，午 后也基本都出现了回涨。整体来看，今日市场表现有所回温，期螺走高，钢坯尾盘上涨20，市场心态也开始好转，故预计明日市场行情或小幅上涨。

The market price is weak. Leading market, Beijing and Tianjin declined slightly, while Shanghai and Guangzhou were mainly stable. Yesterday, the market atmosphere was cold, the square tube manufacturer did not have a good deal, and the mentality was poor. However, with the upswing of the night market, market confidence has been slightly boosted. After all, after several days of downturn, there are signs of upward still worth looking forward to. The opening of the market this morning, the snails did not disappoint the expectations of the high turn red, but the overall trend is not strong, coupled with the recent weak demand, the mindset of the manufacturers is not the same, so today's opening, market prices are weak operation. We know from the market that although today's market prices are generally loose, market feedback is still partially improved. After a slight decline in Beijing, downstream purchases increased, with 10 large households delivering a total of 0.71 million tons, an increase of 0.15 million tons compared with yesterday.

Overall, today's market performance has warmed up, futures snail higher, billet tail up 20, the market mentality has begun to improve, so the market is expected to rise tomorrow or slightly.
