脚手架市场价格主稳个调。主导市场，除了上海小幅反弹外，北京、天津、广州均以稳为主。昨日在期螺反弹的带领下，大部分地区氛围出现回 暖。期螺夜盘的高位平稳运行也给市场带来了支撑，不过早盘的走势就有些差强人意了，开盘震荡走弱，直接影响到了市场的积极性。所以今日开市，市场价格主稳 个调。从市场了解到，随着午后期螺的跌绿，各地氛围再度冷清。北京市场虽然低价资源尚可，但10家大户出货量合计0.66万吨，还是比昨日少了0.08万 吨；杭州市场更是惨不忍睹，大户出货量仅500-1000吨左右，较昨日少了五成之多；广州市场反馈全天成交一般，虽然不算差，但出货量不及昨日。综合上 述分析，预计明日市场行情或弱势调整。

The market price should be adjusted steadily. The dominant market, in addition to a small rebound in Shanghai, Beijing, Tianjin, Guangzhou are mainly stable. Leaded by the rebound of futures snails, the atmosphere in most areas warmed up yesterday. The high and stable operation of futures night disc also brings support to the market, but the trend of early disc is somewhat unsatisfactory. The weakening of opening shocks directly affects the enthusiasm of the market. So when the market opens today, the market price is stable. From the market, we know that with the fall of snails in the late afternoon, the atmosphere around is once again cold. Although the low-cost resources in Beijing market are still acceptable, the total shipment volume of 10 large households is 0.66 million tons, or 0.08 million tons less than yesterday; Hangzhou market is even more tragic, with large household shipments of only 500-1000 tons, less than 50% than yesterday; Guangzhou market feedback is general, although not bad, but the shipment volume is less than yesterday. 。 Based on the above analysis, it is expected that the market will adjust to a weaker position tomorrow. 脚手架价格方面，国内重点城市Ф6.0mm高线平均价格为4102元(吨价，下同),跌2元；国内 重点城市Ф25mm三级螺纹钢平均价格3678元，跌3元。主导城市方面：北京高线(6mm)4770元，持平；三级螺纹钢(25mm)主流规格3600 元，持平；上海市场高线3930元，涨10元；三级螺纹钢3630元，涨10元。
