Ikhoyili Yensimbi Egayiwe(Zinc-coated ) lapho ishidi lensimbi licwiliswa kubhavu we-zinc oncibilikisiwe ukuze ubuso bunamathele eshidini le-zinc.Okwamanje ukusetshenziswa okuyinhloko kwenqubo yokukhiqiza i-zinc eqhubekayo, okungukuthi, ishidi lensimbi eligoqiwe licwiliswa ngaphakathi ukugeza okuncibilika kwe-zinc okwenziwe ngeshidi lensimbi; I-alloy galvanized steel sheet. Lolu hlobo lwepuleti yensimbi lwenziwa ngendlela yokucwilisa eshisayo, kodwa ngemuva kwe-slot, ishisiswe ngokushesha ekushiseni okungaba ngu-500 ℃, lenza isizukulwane se-zinc futhi I-iron alloy membrane.Le khoyili enothayela inokuqina okuhle kokunamathela kanye nokushisela.
