Rau galvanized coils, 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 txuas ntxiv, uas yog, cov hlau phaj yog txuas ntxiv rau hauv lub tank plating nrog zinc melted los ua galvanized steel phaj; alloyed galvanized steel phaj. 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.
