邯郸脚手架市场价格小幅上涨。受唐钢坯和脚手架价格止跌反弹影响，今日邯郸脚手架价格低位上涨20-30元，午前成交课，但午后高位有所转弱。据悉，本地脚手架厂家不多，且多采取钢 厂直发，现货库存很少，故对外报价紧跟成本端。而市场主要是唐山、午汲、传洋、兴华等资源。午后昌黎钢坯涨20，成本暂有支撑，期螺日盘窄幅震荡，继续上 拉动力显不足，市场观望心态转浓，故预计明日邯郸脚手架市场价格稳中偏强调整。

Handan Fangguan market prices rose slightly. Affected by the rebound of Tang steel billet and square pipe prices, the low price of square pipe in Handan rose 20-30 yuan today, closing classes before noon, but the high in the afternoon weakened. It is reported that there are not many local managers, and steel mills are mostly used for direct delivery, and spot inventory is very small, so the external quotation is closely followed by the cost side. The market is mainly Tangshan, Wuji, Chuanyang, Xinghua and other resources. In the afternoon, the billet of Changli Steel increased by 20, the cost was temporarily supported, the daily trading of snails was narrow, the pull-up power was insufficient, and the market wait-and-see mentality became strong. Therefore, it is expected that the market price of Handan Square Pipe will be stable in the middle of the next day.
