Phaephe e chitja e nang le galvanized e chesang ke ho etsa hore tšepe e qhibilihisitsoeng e sebetsane le matrix ea tšepe ho hlahisa lera la alloy, e le ho kopanya matrix le coating. Ho kenya galvanization ka mocheso ho bohlokoa ho qala ka ho seha phaephe ea tšepe. E le ho tlosa oxide ea tšepe holim'a phaephe ea tšepe, kamora ho e seha, phaephe ea tšepe e hloekisoa ka tharollo ea metsi ea ammonium chloride kapa zinc chloride kapa tharollo e tsoakiloeng ea metsi ea ammonium chloride le zinc chloride, ebe e romeloa tankeng ea ho seha e chesang. Ho kenya galvanization ka mocheso ho na le melemo ea ho seha ka mokhoa o ts'oanang, ho khomarela ho matla le bophelo bo bolelele ba ts'ebeletso. Likarabelo tse rarahaneng tsa 'mele le tsa lik'hemik'hale li etsahala pakeng tsa substrate ea phaephe ea tšepe e nang le galvanized e chesang le tharollo ea ho seha e qhibilihisitsoeng, ho etsa lera la alloy ea zinc-iron e hanelang mafome le sebopeho se kopaneng. Lera la alloy le kopantsoe le lera le hloekileng la zinc le matrix ea phaephe ea tšepe. Ka hona, le na le khanyetso e matla ea mafome.

Jwalo ka ha China e le yona kgwebo e etellang pele indastering ya thepa ya tshepe, kgwebo ya naha ya tshepe le thepa "kgwebo e nang le tumelo e ntle ya lekgolo", dikgwebo tsa tshepe tsa China, "dikgwebo tse 100 tse ikgethang tse hodimo Shanghai". Shanghai Zhanzhi industry Group Co., Ltd., (e kgutsufaditsweng ho Zhanzhi Group) e nka "Botshepehi, Bokgoni, Boqapi, Win-Win" e le molaomotheo wa yona feela wa tshebetso, kamehla e phehella ho beha tlhoko ya bareki pele.
