Kuti usangane nezvinodiwa zvakasiyana-siyana zvechimiro chekuwedzera kushandiswa kwekufambira mberi, wedzera hupenyu hwesimbi yakagadziriswa, zinc coating zvinhu zviri kubuda. Mavara matsva makuru ndeaya:

(1) Zinc-iron alloy coating. That galvanized steel after heat treatment. Zvakadai senge diffusion annealing pa500 ~ 550 ℃ 10 ~ 15min, ichapa pombi yakashongedzwa munzvimbo yemafuta kuwedzera hupenyu hunosvika ka9;

(2) Multiple kana galvanized layer ine zvisaririra zvealloying elements. Zvakadai sekuwedzera huwandu hwakakodzera hwenickel inogona kuita ngura pane iyo yakachena electro-galvanized pombi kufambira mberi kanopfuura ka10;

(3) Zvipfeko zvakasanganiswa. Ndiko nekushandiswa kwenzvimbo yezvinodiwa, mune galvanized simbi yakavharwa nedhiri yezvakakodzera organic zvinhu, corrosion yakadai, kupisa kwakanyanya kwekushisa, kutonhora kwekudzivirira, kupfeka kuramba, kukanganisa kupikisa uye kuwedzera kuchinjika, nezvimwewo, tinogona kuenderera mberi nekusangana. imwe kana akati wandei epamusoro zvinodiwa. Kana ruvara runyoro, pamwe nekushongedzwa uye mureza mugumisiro.
