Ishidi elinothayelaiwumkhiqizo ombozwe ungqimba lwe-zinc ebusweni bamashidi ensimbi ajwayelekile ukuze kuthuthukiswe ukumelana nokugqwala kwamashidi ensimbi. Amashidi afakwe uthayela ngokuvamile asebenzisa inqubo yokufaka i-hot-dip galvanizing, ehlanganisa ukucwilisa ishidi lensimbi oketshezini lwezinki oluncibilikisiwe ukuze kwakheke ungqimba olufana nolwezinki oluminyene. Lokhu kwelashwa kunikeza amashidi akhandiwe ukumelana nokugqwala okuhle kakhulu, ukumelana nokuguga kanye nokumelana nesimo sezulu.
Amashidi anamathangi asetshenziswa kakhulu ekwakheni, ifenisha, ukukhiqiza izimoto, ugesi, ezokuxhumana kanye neminye imikhakha. Emkhakheni wokwakha, amashidi ama-galvanized avame ukusetshenziselwa ukwenza uphahla, izindonga, amapayipi, iminyango namafasitela, njll, ngoba ukumelana nokugqwala kwabo kungandisa ngokuphumelelayo impilo yabo yenkonzo. Ekwenziweni kwefenisha, amashidi anathayela angasetshenziswa ukwenza ifreyimu yensimbi negobolondo lefenisha ukuze kuthuthukiswe ukuqina komkhiqizo. Ekwenziweni kwezimoto, amashidi anothayela angasetshenziswa ekwenzeni amaphaneli omzimba wezimoto ukuthuthukisa ukuqina kwemoto. Emkhakheni wamandla nokuxhumana, amashidi anama-galvanized angasetshenziswa ukwenza ama-cable sheaths, ama-casings emishini yokuxhumana, njll, ngoba ukumelana nokugqwala kungaqinisekisa ukusebenza okuphephile kwemishini.
Ngokuvamile, amashidi akhandisiwe abe enye yezinto ezibalulekile emikhakheni ehlukahlukene yezimboni ngenxa yokumelana nokugqwala okuhle kakhulu kanye nobubanzi bezicelo.
