Chitsulo cha galvanized ndi chitsulo choviikidwa choviikidwa chomwe chimapereka makasitomala kukana bwino kwa malo owononga.

Kuti apange malata, zitsulo zoziziritsa kuzizira zimamizidwa mu bafa yosungunuka ya zinki, yotchedwa hot-dip process (malata amathanso kutheka chifukwa cha malata mosalekeza). Pamene zakuthupi amachotsedwa kusamba nthaka ndi utakhazikika anachita kwa mpweya mu mlengalenga zimachitika. Zomwe zimachititsa kuti zokutira za zinki zikhale gawo la chitsulo chomwe chimapanga chomaliza chodziwika bwino.

Koyela Wachitsulo Wotentha-Dip ili ndi magwiridwe antchito abwino kwambiri, okhala ndi zida zomveka bwino za kukana dzimbiri, mapangidwe ndi zokutira. Amapangidwa podutsa pepala lachitsulo lomwe lakhala likutsukidwa ndi asidi ndikugudubuza mumphika wa zinki, potero amapaka filimu ya zinki pamwamba. Ili ndi kukana kwa dzimbiri, kupendekeka, komanso kugwira ntchito chifukwa cha mawonekedwe a Zinc
