Cov yeeb nkab steel muaj hollow seem, thiab nws qhov ntev yog ntau dua li txoj kab uas hla lossis ib puag ncig ntawm cov hlau.Raws li cov duab seem, nws tau muab faib ua voj voog, square, duab plaub thiab tshwj xeeb-puab steel kav;Raws li cov khoom siv, nws tau muab faib ua carbon structural steel yeeb nkab, qis alloy steel yeeb nkab, alloy steel yeeb nkab thiab cov yeeb nkab steel yeeb nkab;Nws tau muab faib ua cov kav dej steel rau cov kav xa dej, cov qauv tsim hluav taws xob, cov khoom siv thermal, kev lag luam petrochemical, kev tsim cov tshuab, geological drilling, cov cuab yeej siv siab, thiab lwm yam;Raws li cov txheej txheem ntau lawm, nws tau muab faib ua seamless steel yeeb nkab thiab welded steel yeeb nkab.Seamless steel yeeb nkab yog muab faib ua kub dov thiab txias dov (kos duab), thiab welded steel yeeb nkab yog muab faib ua ncaj seam welded steel yeeb nkab thiab kauv seam welded steel yeeb nkab.
Tuam Tshoj yog tus tsim khoom tseem ceeb ntawm cov kav hlau hauv ntiaj teb.Xyoo 2020, cov khoom lag luam tawm hauv lub tebchaws yog 89.5427 lab tons, nrog rau xyoo tas los nce ntawm 3.73%, suav txog li 60% ntawm lub ntiaj teb cov khoom tsim tawm.Nyob rau tib lub sijhawm, lub voj voog khoom ntawm cov yeeb nkab steel kev lag luam yog ze rau cov txiaj ntsig ntawm kev tsim kho vaj tse, kev tswj hwm hauv nroog thiab kev tsim khoom lag luam.Yog li ntawd, nyob rau hauv kev ua raws li "14th tsib xyoos txoj kev npaj" thiab txoj cai tshiab infrastructure, cov khoom ntawm Tuam Tshoj txoj kev lag luam steel yeeb nkab yuav txuas ntxiv kom muaj kev loj hlob.
