Qhov sib txawv tseem ceeb ntawm galvanized steel ntawv thiab aluminium-zinc plated steel ntawv nyob hauv lawv cov txheej. Qhov saum npoo ntawm galvanized steel ntawv yog tusyees coated nrog zinc, uas plays lub luag hauj lwm ntawm anodic tiv thaiv rau lub hauv paus khoom. Hauv lwm lo lus, kev hloov corrosion ntawm cov khoom siv zinc tiv thaiv kev siv cov khoom siv hauv paus. Tsuas yog thaum tag nrho cov zinc corroded tuaj yeem ua rau cov khoom siv hauv paus puas.
Cov txheej txheej ntawm aluminium-zinc plated steel ntawv yog tsim los ntawm 55% txhuas, 43.5% zinc, thiab lwm yam khoom me me. Nyob rau hauv ib lub tshuab ntsuas, lub txhuas-zinc txheej saum npoo zoo li cov qauv honeycomb, nrog zinc nyob rau hauv "honeycombs" tsim los ntawm txhuas. Nyob rau hauv cov ntaub ntawv no, txawm hais tias lub aluminium-zinc txheej kuj plays lub luag hauj lwm ntawm anodic tiv thaiv, nyob rau hauv ib tes, vim txo cov zinc cov ntsiab lus thiab ntawm qhov tod tes, vim lub fact tias zinc cov ntaub ntawv yog qhwv los ntawm txhuas thiab tsis yooj yim. yuav tsum tau electrolyzed, cov nyhuv ntawm anodic tiv thaiv yog heev txo. Yog li ntawd, ib zaug aluminium-zinc plated steel ntawv raug txiav, cov npoo uas tsis muaj kev tiv thaiv hauv qab txiav yuav sai sai. Yog li ntawd, aluminium-zinc plated steel los xij yuav tsum tau txiav kom tsawg li sai tau. Thaum txiav, cov npoo yuav tsum tau tiv thaiv nrog cov xim pleev xim los yog zinc-nplua nuj xim kom ntev kev pab cuam lub neej ntawm daim ntawv.
Qhov saum npoo ntawm aluminium-zinc plated steel ntawv yog zoo nkauj dua li ntawm galvanized steel ntawv. Lub caij no, tus nqi ntawm aluminium-zinc plated steel ntawv yog kim dua li ntawm galvanized steel ntawv, thiab tus nqi ntawm cov paj me me zinc yog kim dua li cov paj zinc loj.
