Cov Nkoj Tshwj Xeeb: Cov nkoj tawg dej khov, cov nkoj tshawb fawb polar, thiab lwm hom nkoj uas xav tau kev ruaj khov siab thiab qis thaum kub thiab txias
Chaw Nres Nkoj thiab Chaw Nres Nkoj: Cov qauv chaw nres nkoj qhuav thiab cov khoom siv nqa ntawm ntug dej hiav txwv
Lub teb chaws Yelemees, Belgium, Netherlands, thiab Ltalis yog cov thawj coj European importers ntawm S355J2H square tubes. Cov chaw nres nkoj ntawm Antwerp (Belgium) thiab Rotterdam (Netherlands) ua haujlwm ua cov chaw faib khoom loj hauv Tebchaws Europe, tuav cov ntim loj transshipment.
3. Kev Tshuaj Xyuas Qhov Ntim Khoom Ntshuam
Raws li kev kwv yees cov ntaub ntawv kev lag luam, Tuam Tshoj txoj kev xa tawm txhua xyoo ntawm S355J2H square tubes mus rau European kev lag luam tseem nyob hauv qhov ntau ntawm kwv yees li 170,000 txog 220,000 tonnes thaum xyoo 2022-2023. Cov khoom lag luam Suav tau tswj hwm qhov tseem ceeb ntawm kev lag luam hauv Tebchaws Europe vim muaj kev ruaj khov zoo thiab kev sib tw nqi. Txawm hais tias EU txoj cai tiv thaiv kev pov tseg rau qee cov khoom lag luam hlau Suav, kev muab khoom Suav tseem ceeb hauv cov ntu hollow.
4. Cov Lus Qhia Txog Kev Ntshuam Khoom Siv
Kev lag luam European feem ntau xa cov raj S355J2H square hauv cov lus qhia hauv qab no:
Cov Qauv Ntau Yam Sib Xws
