Raws li galvanized steel coils, yog cov ntawv hlau yog immersed nyob rau hauv ib tug molten zinc da dej los ua ib daim ntawv ntawm zinc coated rau nws nto.Nws yog tsuas yog tsim los ntawm cov txheej txheem galvanizing tas li, uas yog, cov ntawv hlau dov tau txuas ntxiv rau hauv lub tank plating nrog zinc melted los ua galvanized steel daim hlau;alloyed galvanized steel ntawv.Cov hlau phaj no kuj yog tsim los ntawm kub dip txoj kev, tab sis tam sim ntawd tom qab tawm ntawm lub tank, nws yog rhuab mus txog 500 ℃ los ua ib tug alloy txheej ntawm zinc thiab hlau.Qhov no galvanized kauj muaj cov xim zoo adhesion thiab weldability.
Zinc txheej yog muab faib ua: ib txwm spangle txheej, me me spangle txheej, tsis muaj spangle txheej, zinc-hlau alloy txheej, sib txawv thickness txheej thiab daim tawv nqaij dhau.
