iikhoyili ezenziwe ngesinyithi, Isixhobo sensimbi esithintela ukubola kwentsimbi ngokubeka umaleko we-zinc kumphezulu we-coil yensimbi. Iikhoyili eziphehliwe zivame ukutshisa i-galvanizing, apho i-coil yensimbi ifakwe kwisisombululo se-zinc etyhidiweyo ukwenzela ukuba i-uniform zinc layer iqulunqwe phezu kwayo. Olu nyango lunokuthintela ngokufanelekileyo intsimbi ukuba ikhutshwe ngumoya, amanzi kunye neekhemikhali, kwaye yandise ubomi bayo benkonzo.
Ikhoyili eyenziwe ngegalvanized inokumelana ne-corrosion, amandla aphezulu kunye nobunzima, ukusebenza kakuhle kokusebenza kunye nokusebenza kokuhombisa. Isetyenziswa kakhulu kulwakhiwo, ifenitshala, ukwenziwa kweemoto, izixhobo zombane kunye namanye amacandelo. Kwishishini lokwakha, iiroli ezinamazinki zihlala zisetyenziselwa ukwenza amacandelo afana nophahla, iindonga, imibhobho kunye neengcango kunye neeWindows ukuphucula ukumelana nokubola kunye nobuhle. Kwishishini leemoto, iikhoyili ezenziwe ngamagalvanized zisetyenziselwa ukwenza amaqokobhe omzimba kunye namalungu okunyusa ukumelana nemozulu kunye nokuqina.
Ngokuqhelekileyo, i-coil galvanized ine-resissional corrosion resistance and mechanical properties, kwaye iyinto ebalulekileyo yentsimbi edlala indima ebalulekileyo ekukhuseleni intsimbi ekungcoleni kunye nokwandisa ubomi bayo benkonzo.
