Ukuhlangabezana neemfuno ezahlukeneyo zesiseko sokwandisa ukusetyenziswa kwenkqubela phambili, ukwandisa ubomi bentsimbi ye-galvanized, izinto zokugqoka i-zinc ziyaguquka. Iingubo ezinkulu ezintsha zezi:

(1) I-zinc-iron alloy coating. Loo ntsimbi yentsimbi emva konyango lobushushu. Okufana nokusasazwa kwe-annealing kwi-500 ~ 550 ℃ 10 ~ 15min, iya kunika umbhobho ofakwe izizinki kwindawo yeoli yandisa ubomi phantse amaxesha ali-9;

2 Okufana nokongeza isixa esifanelekileyo se-nickel sinakho ukubola kuneso lenkqubela ecocekileyo ye-electro-galvanized pipe ngaphezu kwamaxesha ali-10;

(3) Iingubo ezidibeneyo. Oko kukusetyenziswa kwesiseko sesidingo, kwintsimbi efakwe intsimbi egqunywe ngomaleko wezinto eziphilayo ezifanelekileyo, ukubola okunjalo, ukumelana nobushushu obuphezulu, ukumelana nokubanda, ukumelana nokunxiba, ukumelana nefuthe kunye nokwandisa ukuguquguquka, njl. enye okanye ezininzi iimfuno eziphezulu. Ukuba umbala ukutyabeka, kwakunye imihombiso kunye nefuthe iflegi.
