Hlau nrog lub hollow seem uas nws qhov ntev yog ntau dua li nws txoj kab uas hla los yog ib ncig. Raws li tus ntoo khaub lig-sectional duab, nws muab faib ua voj voog, square, rectangular thiab tshwj xeeb-zoo li tus steel kav; Raws li cov khoom siv, nws tau muab faib ua carbon structural steel kav, tsis tshua muaj hlau alloy steel kav, alloy steel kav thiab puas steel kav; Cov kav hlau steel rau cov khoom siv thermal, kev lag luam petrochemical, kev tsim khoom, geological drilling, cov cuab yeej siv siab, thiab lwm yam .; Raws li cov txheej txheem ntau lawm, lawv tau muab faib ua seamless steel kav thiab welded steel kav, ntawm cov seamless steel kav muab faib ua kub dov thiab txias dov (kos) Ob hom, welded steel yeeb nkab yog muab faib ua ncaj seam welded steel yeeb nkab. thiab kauv seam welded steel yeeb nkab.
Cov yeeb nkab steel yog siv los hloov cov kua dej thiab hmoov, pauv cov cua sov thiab tsim cov khoom siv kho tshuab thiab ntim khoom, dab tsi ntxiv nws yog hom kev lag luam steel. Siv cov kav dej steel los tsim cov qauv vaj tsev, ncej thiab cov cuab yeej txhawb nqa tuaj yeem txo qhov hnyav, txuag tau 20-40 feem pua ntawm cov hlau, thiab paub txog lub Hoobkas zoo li kev tsim kho tshuab. Kev siv cov yeeb nkab steel los tsim cov kev loj txuas txuas tsis tau tsuas yog txuag cov hlau thiab ua kom yooj yim rau kev tsim kho, tab sis kuj txo qis thaj tsam ntawm cov txheej txheem tiv thaiv, txuag peev nyiaj thiab kev saib xyuas.
