Ntau qhov kev lag luam sib txawv siv galvanized steel feem ntau vim tias nws muaj ntau yam txiaj ntsig zoo rau kev lag luam kom tau txais txiaj ntsig, suav nrog:
Tus nqi pib qispiv rau feem ntau kho steels. Tsis tas li ntawd, galvanized steel yog tam sim ntawd npaj siv thaum xa khoom. Nws tsis xav tau kev npaj ntxiv ntawm qhov chaw, tshuaj xyuas, pleev xim / txheej, thiab lwm yam. sparing tuam txhab uas muag ntau tus nqi ntawm lawv qhov kawg.
Lub neej ntev.Nrog galvanization, ib daim ntawm cov hlau ua lag luam yuav tsum kav ntev tshaj 50 xyoo nyob rau hauv nruab nrab ib puag ncig, thiab tuaj yeem kav ntev tshaj 20 xyoo nrog dej loj heev. Tsis tas yuav tsum muaj kev saib xyuas. Qhov nce durability ntawm steel cov khoom tiav kuj ua rau cov khoom muaj kev ntseeg siab.
Lub sacrificial anodexyuas kom meej tias cov hlau puas raug tiv thaiv los ntawm ib puag ncig zinc txheej. Nws tsis muaj teeb meem yog tias cov hlau seem raug puas lawm; cov zinc tseem yuav corrode ua ntej. Cov txheej yuav corrode nyiam rau cov hlau, tsim kom muaj kev tiv thaiv kev txi rau cov chaw uas puas lawm.
Kev tiv thaiv xeblos ntawm zinc txheej. Cov ntsiab lus hlau hauv cov hlau tsis txaus ntseeg yuav ua rau xeb, tab sis qhov sib ntxiv ntawm zinc ua raws li kev tiv thaiv ntawm cov hlau thiab cov dej noo lossis oxygen.Galvanized hlaumuaj kev tiv thaiv zoo heev, suav nrog cov kaum ntse ntse thiab cov chaw so uas tsis tuaj yeem tiv thaiv nrog lwm cov txheej txheem, ua rau nws tiv taus kev puas tsuaj.
