Palo ea galvanized e nyane haholo, ke 10-50g / m2 feela. Ho hanyetsa ha eona ha kutu ho fapane haholo le peipi e kentsoeng ka masenke a chesang. E le ho netefatsa boleng, bahlahisi ba bangata ba kamehla ba liphaephe tsa galvanized ha ba sebelise electro galvanizing (ho batang ka ho bata). Ke likhoebo tse nyane feela tse nang le lisebelisoa tse nyane le tsa khale tse sebelisang electro galvanizing, ehlile, theko ea tsona e batla e le theko e tlase. Lekala la khaho le phatlalalitse ka molao hore lipeipi tsa masenke tse batang tse nang le mahlale a morao li tla felisoa, li se ke tsa sebelisoa e le lipeipi tsa metsi le tsa khase. The galvanized lera ea batang galvanized tšepe phala ke lera electroplating, 'me lera zinki arotsoe ho tloha tšepe phala substrate.
