Tepi yakarukwainotangira pakutanga kwezana remakore rechi19. Panguva iyoyo, nekufambira mberi kweIndustrial Revolution, kugadzirwa nekushandiswa kwesimbi kwakawedzera nekukurumidza. Nekuti simbi yenguruve nesimbi zvinowanzo ngura kana zvasangana nehunyoro neokisijeni, masayendisiti akatanga kutsvaga nzira dzekudzivirira ngura.
Muna 1836, musayendisiti wekuFrance Antoine Henri Becker akatanga kutaura nezvepfungwa yekuputira zinc pamusoro pesimbi kana simbi kudzivirira ngura. Nzira iyi yakazozivikanwa sekupisa dip galvanizingNekuvandudzwa kwetekinoroji iyi, tepi yesimbi yakagadzirwa zvishoma nezvishoma uye yakashandiswa zvakanyanya.
Muzana remakore rechi20, nekufambira mberi kuri kuramba kuchiita tekinoroji ye galvanizing, maitiro akasiyana-siyana akadai se electroplating uye hot plating akaonekwa imwe mushure meimwe, zvekuti kushanda zvakanaka kwekugadzira uye kudzivirira ngura kwe galvaning tape kwave kuvandudzwa nguva dzose. Kufambira mberi uku kwakakurudzira kushandiswa kwakakura kwe galvaning tape mumaindasitiri akawanda akadai sekuvaka, mota, nemidziyo yemumba, zvichiumba musika wakura watinoona nhasi.
Tepi yesimbi yakashandiswa zvakanyanya mumaindasitiri akawanda nekuda kwekudzivirira kwayo ngura uye kushanda kwayo zvakanaka. Mubasa rekuvaka, tepi yesimbi inoshandiswa muzvivakwa zvesimbi, matenga nemadziro, izvo zvinogona kuwedzera hupenyu hwebasa. Muindasitiri yemotokari, tepi yesimbi inoshandiswakugadzira zvikamu zvemuvirikuvandudza kusimba kwengura uye kuchengetedzeka. Maindasitiri emidziyo nefenicha anoshandisawo sechinhu chakakosha pakuvandudza kugara kwenguva refu uye runako rwezvigadzirwa zvavo.
Mune ramangwana, nekuwedzera kwemitemo yezvakatipoteredza yakaoma uye mafambiro ekuvaka zvakatipoteredza uye budiriro inoenderera mberi, kudiwa kwemabhandi emagetsi kunotarisirwa kuramba kuchikura. Kuvandudzwa kwezvinhu zvitsva uye kufambira mberi kwetekinoroji kuchaenderera mberikuvandudza mashandiro etepi yakabatidzwauye kuwedzera nzvimbo yayo yekushandisa. Nokudaro, mikana yese yekuvandudza tepi yegalvanized ine tariro huru, uye yave chinhu chakakosha muindasitiri dzakasiyana-siyana.
