Galvanized steel hais tias cov pa roj carbon zoo tib yam siv hlau tuaj yeem tiv thaiv cov hlau los ntawm kev xeb thiab xeb thiab ua kom lub neej ntev ntawm cov hlau tom qab tau galvanized, suav nrog galvanization thiab kub dip galvanization. Feem ntau, nws yog feem ntau siv rau kev tsim cov phab ntsa sab nrauv, xws li iav ntaub thaiv phab ntsa, marble curtain phab ntsa, aluminium curtain phab ntsa raws li txhua kab thiab cov ntaub ntawv kev ntxhov siab, los yog rau sab nraum zoov telecommunications yees, txoj kev loj thiab lwm lub tsev sab nraum zoov. Cov hlau yog hu ua galvanized steel, uas galvanization muab faib ua electrogalvanizing thiab kub-dip galvanizing.
Galvanized steel feem ntau suav nrog cov khoom tseem ceeb hauv qab no: ua ntej, hlau, uas yog cov khoom tseem ceeb ntawm cov hlau. Qhov sib txawv ntawm hlau thiab hlau yog nyob rau hauv cov ntsiab lus carbon. Hlau muaj qis carbon cov ntsiab lus, yog li nws muaj zoo toughness thiab hardness. Qhov thib ob yog leej faj, tab sis nws yog ib qho teeb meem impurity. Thaum cov hlau nrog cov ntsiab lus sulfur yog ua tiav ntawm qhov kub thiab txias, nws yooj yim rau embrittlement; Tsis tas li ntawd, muaj phosphorus keeb. Phosphorus yuav txo cov plasticity thiab toughness ntawm hlau, uas yuav pom tseeb dua nyob rau hauv qis kub. Yog li ntawd, nyob rau hauv high-zoo galvanized steel cov ntaub ntawv, cov ntsiab lus ntawm leej faj thiab phosphorus yuav tsum tau nruj me ntsis tswj los xyuas kom meej qhov zoo ntawm galvanized hlau.
