Kub dip galvanized steel sawb yeej ib txwm muaj ntau yam tsis tshua muaj nyob hauv Suav teb kev lag luam.Txij li thaum nruab nrab-1990s, kwv yees li 800000-1million tons tau tuaj txawv teb chaws txhua xyoo.Nrog rau txoj kev loj hlob ntawm kev lag luam hauv tsev, tshwj xeeb tshaj yog kev tsim tsheb, khoom siv hauv tsev thiab kev tsim kho kev lag luam, qhov kev thov rau galvanized sawb steel kuj tau nce ntau heev.Tuam Tshoj tau tsim ib pawg ntawm cov kab ntau lawm nrog cov khoom tsim tawm txhua xyoo ntau tshaj 100000 tons hauv 20 xyoo tsis ntev los no, tab sis cov kub-dip galvanizing units nrog cov cuab yeej siv qis qis ntawm cov txheej txheem ntws, cov khoom muaj pes tsawg leeg thiab cov khoom ntau yam tsis tuaj yeem ua tau raws li cov khoom siv. kev xav tau ntawm Tuam Tshoj txoj kev lag luam kev tsim kho thiab kev loj hlob nyob rau hauv cov nqe lus ntawm ntau yam, zoo thiab ntau, thiab tshiab kub-dip galvanizing kab tseem yuav tsum tau tsim kom tau raws li cov kev xav tau ntawm lub khw.
Txij li thaum xyoo 1990, kev tsim cov ntawv hlau galvanized hauv Suav teb tau ua tiav zoo, thiab kev ua tiav ntawm galvanized steel ntawv hauv Suav teb tau txog ze li 3 lab tons.Kev sib koom ua lag luam ntawm cov ntawv galvanized hauv tsev tau nce sai, los ntawm kwv yees li 27% hauv 1996 txog li 59% hauv 1998. Lub tuam txhab tseem ceeb hauv tsev yog Baosteel, Wuhan Hlau thiab hlau, Panzhihua Hlau thiab hlau, Handan Hlau thiab hlau, Benxi Hlau thiab hlau. , nrog tag nrho cov peev txheej ntau dua 1.3 lab tons.
