Maitiro ekugadzira simbi nesimbi anochinja zvakanyanya kana zvasvika pakudzivirira simbi kubva mukuora. Nekuputira simbi nesimbi nesimbi, simbi dzinoshandiswa musimbi dzinova simba guru munyika yekudzivirira simbi. Ngationgororei zvakadzama nezvemaitiro aya toongorora kushamisa kwemaruva esimbi uye kukanganisa kwayo kugara kwenguva refu kwesimbi.
Maitiro ekugadzira simbi anosanganisira kunyudza simbi mubhavhu rezinc yakanyungudutswa, zvichigadzira jira rinodzivirira simbi iri pasi kubva kuzvinhu zvakatipoteredza. Maitiro aya haangopi chete kudzivirirwa kubva mukuora, asiwo anopa dziviriro ye cathodic, zvinoreva kuti zinc inozvipira pachayo kudzivirira simbi kubva mukuora nekuora.
Chinhu chinonakidza pakugadzira galvanizing process ndiko kugadzirwa kwe zinc splatter. Mapatani aya akasiyana ekristaro anokonzerwa nekutonhorera nekusimba kwe zinc layer. Maruva e zinc haangowedzere runako chete kuma galvanized coils, asiwo anoratidza kunaka uye ukobvu hwe protective zinc layer, zvichishanda sevimbiso inooneka yekugara kwenguva refu kwesimbi.
Coil yesimbi inoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana, anosanganisira kuvaka, mota uye kugadzira nekuda kwekudzivirira kwayo ngura uye hupenyu hwayo hwekushanda. Zinc layer inoshanda sechidziviriro, ichivimbisa kuti simbi inoramba yakadaro kunyangwe munzvimbo dzakaoma, zvichiita kuti ive yakakodzera kushandiswa panze uye zvikamu zvechivakwa.
Pamusoro pekudzivirira kwayo, galvanized coil inozivikanwawo nekushomeka kwayo pakugadzirisa, zvichiita kuti ive mhinduro isingadhuri yekushandisa kwenguva refu. Kugara kwenguva refu uye kuvimbika kwesimbi yegalvanized kunoita kuti ive mari inokosha kumabhizinesi ari kutsvaga kuderedza mari yekutsiva nekugadzirisa.
Muchidimbu, maitiro ekugadzira magasi, nemaspangles ayo uye machira ekudzivirira, humbowo hwesimba rekuchengetedza simbi. Nekusarudza magasi, maindasitiri anogona kubatsirwa nekugara kwenguva refu, hupenyu hwebasa hwakareba uye kuderedzwa kwekugadzirisa, zvichizopedzisira zvaita kuti pave nekuchengetedza kwenguva refu uye rugare rwepfungwa.
Kuisa nzira yekuisa simbi musimbi hakusi kungodzivirira chete; kuvimbisa kugara kwenguva refu uye kusimba. Nesimba rema coil e zinc, ramangwana resimbi rakajeka kupfuura kare.
