Letlapa la tšepe le entsoeng ka galvanized ke ho thibela bokaholimo ba tšepe hore bo se ke ba senyeha le ho lelefatsa bophelo ba eona ba ts'ebeletso, 'me bokaholimo ba tšepe bo koahetsoe ka lera la zinki.
Ho latela mekhoa ea tlhahiso le ts'ebetso, e ka aroloa ka mekhahlelo e latelang:
1 Letlapa le chesang la galvanized. Letlapa la tšepe le qoelisoa ka bateng ea zinki e qhibilihisitsoeng, 'me lesela la zinki le khomaretsoe holim'a lona. Hajoale, e hlahisoa haholo ke ts'ebetso e tsoelang pele ea galvanizing, ke hore, poleiti ea galvanized e entsoe ka ho qoelisoa lipoleiti tsa tšepe tse kolobisitsoeng ka ho tsoelang pele ka tanka ea plating moo zinki e qhibilihang;
2 Alloy galvanized sheet. Mofuta ona oa poleiti ea tšepe e boetse e etsoa ka mokhoa oa hot-dip, empa ka mor'a hore e tsoe ka tanka, e futhumatsoa hoo e ka bang 500 ℃ hang-hang ho etsa filimi ea alloy ea zinki le tšepe. Letlapa lena le nang le galvanized le na le sekhomaretsi se setle sa pente le ho chesehela;
3 Letlapa la tšepe ea elektro-galvanized. Letlapa la tšepe le entsoeng ka mokhoa oa electroplating le na le mosebetsi o motle. Leha ho le joalo, ho roala ho tšesaane, 'me khanyetso ea kutu ha e ntle joaloka ea lesela le chesang la galvanized;
4 Litšepe tse fapaneng tsa mahlakore a le mong le tse mahlakore a mabeli. Letlapa le nang le lehlakore le le leng la galvanized, ke hore, sehlahisoa se kentsoeng ka lehlakoreng le le leng feela. Ho tjheseletsa, ho penta, kalafo e thibelang mafome, ho sebetsa, joalo-joalo, e na le maemo a betere ho feta lakane e nang le mahlakore a mabeli. E le ho hlōla bothata ba hore lehlakore le leng ha le koahetsoe ka zinki, ho na le lakane e 'ngoe e entsoeng ka masenke e koahetsoeng ka lesela le tšesaane la zinki ka lehlakoreng le leng, ke hore, lakane e nang le mahlakore a mabeli a fapaneng;
5 Alloy, letlapa la tšepe le kopantsoeng. E entsoe ka zinki le litšepe tse ling tse kang aluminium, lead, zinki, joalo-joalo ho etsa li-alloys kapa esita le lipoleiti tsa tšepe tse entsoeng ka motsoako. Mofuta ona oa tšepe ea tšepe ha o na ts'ebetso e ntle ea ho thibela mafome feela, empa hape o na le ts'ebetso e ntle ea ho roala;
Ho phaella mefuteng ena e mehlano e ka holimo, ho boetse ho na le lishiti tse mebala-bala tse entsoeng ka masenke, lishiti tsa tšepe tse hatisitsoeng le tse pentiloeng, le lishiti tsa PVC tse entsoeng ka selamite. Empa e sebelisoang ka ho fetesisa e ntse e le lakane ea masenke a chesang.
