錐形鋼管
        

錐形鋼管市場終于沒有抵抗住最新一輪的下跌潮，且出貨冷清，整個市場看空情緒較濃。無縫管現貨報價跟隨上游市場小幅下跌。商家反應目前工地不少已經收尾，因此降價以后，出貨情況仍然不盡如人意，對于目前的狀況貿易商也很無奈。部分無縫管商家表示，若上游持續弱勢運行，不排除后市仍有進一步下跌的可能。Y軸IxSxrxIySyryln.ln.Lb.ln.2ln.4ln.3ln.ln.4ln.3ln.20×12.50001/2103.3030.416501657.37750125.04.97.37503/878.5223.112801287.4458397.25.03.31255/1665.8719.410801087.4749582.55.0620×8.50001/289.6826.412701276.9430075.13.38.37503/868.3120.198898.87.0223659.13.43.31255/1657.3616.983883.87.0520250.43.4620×4.50001/276.0722.488988.96.3161.630.81.66.37503/858.1017.169969.96.4050.325.11.72.31255/1648.8614.459659.66.4443.721.81.7418×6.50001/276.0722.481890.96.0514147.22.52.37503/858.1017.164171.36.1311337.62.57.31255/1648.8614.454660.76.1797.032.32.6016×12.50001/289.6826.49621206.04618103.04.84.37503/868.3120.174893.56.1148280.34.90.31255/1657.3616.963579.46.1440968.24.9316×8.50001/276.0722.472290.25.6824461.03.30.37503/858.1017.156570.65.7519348.23.36.31255/1648.8614.448160.15.7916541.23.3916×4.50001/262.4618.448160.25.1249.324.61.64.37503/847.9014.138247.85.2140.420.21.69.31255/1640.3511.932740.95.2535.117.61.7214×10.50001/276.0722.460886.95.2236172.34.02.37503/858.1017.147668.05.2828456.84.08.31255/1648.8614.440557.95.3124248.44.11
