1) Lub corrosion kuj ntawm aluminium-zinc xim-coated ntawv yog 3 mus rau 5 npaug ntawm galvanized xim-coated ntawv, thiab qhov hnyav dua corrosion, qhov sib txawv ntau dua, yog li hauv tsev ru tsev, aluminium-zinc xim-coated ntawv. AZ150 yuav tsum nyiam. Yog tias cov ntawv galvanized xim-coated raug xaiv, nws yuav tsum tsis txhob tsawg dua Z275, thiab nws lub neej kev pab cuam tsawg dua li ntawm AZ150. Yog li ntawd, Australia thiab lwm lub teb chaws tau hais meej meej tias yog galvanized colour-coated ntawv yog siv rau vov tsev (phab ntsa), Z450 yuav tsum tau siv.
2) AZ150 yog kwv yees li 10-20% kim tshaj Z275, tab sis nws cov corrosion kuj yog ntau tshaj 3 mus rau 5 zaug. Nws tuaj yeem pom tias cov ntawv txhuas-zinc xim-coated muaj qhov ua tau zoo-rau-tus nqi piv.
