Ob lub ntsiab lus tseem ceeb ntawm coated panels yog zinc, aluminium, thiab aluminium-zinc, peb cov khoom siv alloy. Zinc feem ntau sawv cev los ntawm Z. Z yog cov ntawv luv ntawm Askiv Zinc. Piv txwv li, Z80 nto zinc plating cov ntsiab lus yog 80 grams ib square. Z100 txhais tau tias cov ntsiab lus galvanizing yog 100 grams ib square meter, thiab lwm yam. Tus lej tom qab Z qhia qhov nruab nrab txheej txheej ntawm peb lub ntsiab lus ntawm ob sab ntawm galvanized steel kauj hauv grams ib square meter.
Cov ntaub ntawv dav dav ntawm kub-dip galvanizing ntawm lub khw yog: Z80, Z100, Z120, Z140, Z180,Z275, thiab lwm yam. Aluminium yog sawv cev los ntawm A. A yog cov ntawv luv ntawm Aluminium hauv lus Askiv.
Aluminium-zinc compounds yog tsim los ntawm Z thiab A ntxiv ua ke. Zoo li AZ150. Galvalume yog hlau alloy. Ntawm cov galvalume tebchaw, cov proportions ntawm txhuas thiab zinc yog: txhuas 55%, zinc 43.5%, thiab silicon 1.5%. Ntawm cov cim galvalume, AZ100 txhais tau tias cov ntsiab lus galvanized yog 100 grams ib square, AZ70 txhais tau tias cov ntsiab lus galvanized yog 70 grams ib square, thiab AZ150 txhais tau hais tias cov ntsiab lus galvanized yog 150 grams ib square. Cov khoom siv ntawm galvanized coils hauv khw feem ntau suav nrog: AZ50, AZ70, AZ100, AZ150, AZ180, thiab AZ200. Ntawm lawv, AZ50 feem ntau yog tsim los ntawm cov nroj tsuag me me hauv tsev (steel phaj foundries). Cov hlau me me saum AZ100 tsis tuaj yeem tsim tau, thiab feem ntau pom muaj nyob rau hauv cov hlau loj, xws li Shangxing, Yehui, Baosteel, United, GNEE, thiab lwm yam. Tsis tas li ntawd, muaj tsawg tsawg AZ180 thiab AZ200 cov khoom lag luam hauv khw, thiab cov khoom siv hauv tsev. thev naus laus zis tuaj yeem ncav cuag AZ220 grams ib square meter.
Txij li feem ntau ntawm cov phaj coated yog nyias daim hlau, lub thickness feem ntau tsis ntau tshaj 4.0 hli tuab, yog li cov ntsiab lus txheej yog delineated. Qhov ntawd yog hais tias, yog tias cov ntsiab lus txheej yog siab dhau lawm, cov txheej txheem txheej txheej hauv tsev tam sim no tsis tuaj yeem ua tiav qhov du thiab zoo nkauj (piv txwv li, Z600 zinc txheej yog qhov tsis zoo nkauj li Z275 zinc txheej). Nyob rau hauv galvanizing, vim lub siab tshaj plaws domestic technology, galvanizing tuaj yeem ncav cuag 220 grams ib square meter, thiab galvanizing tsis tuaj yeem welded. Yuav kom ua tau raws li cov khoom xav tau ntau dua, cov phaj hlau hu ua aluminium-magnesium-zinc tau yug los raws li kev lag luam xav tau. Aluminium-magnesium-zinc steel daim hlau kuj yog txhuas-zinc tebchaw, tab sis muaj pes tsawg leeg ntawm cov txheej txheej ntawm cov hlau phaj txheej tau hloov pauv. Ntawm cov txheej txheem txheej ntawm aluminium-magnesium-zinc steel daim hlau, txhuas nyiaj rau 5-11%, zinc nyiaj rau 84.5%, magnesium account rau 3%, thiab silicon nyiaj rau 1.5%. Txij li thaum cov txhuas tivthaiv tau ntxiv rau zinc, qhov tsis zoo ntawm galvanizing raws li kev tiv thaiv corrosion thiab lwm yam zoo dua. Nyob rau tib lub sijhawm, kev faib ua feem ntawm zinc cov khoom yog siab, uas tuaj yeem ua tiav 55% aluminium-zinc plating thiab txheej txheej tsis tuaj yeem tshaj qhov txwv ntawm AZ220. Aluminium-magnesium-zinc feem ntau muaj txhuas-zinc txheej uas tuaj yeem ua AZ220, AZ275, thiab lwm yam.
