Ishiti elenziwe ngegalvanized libhekiselele kwiphepha lentsimbi eliqatywe nge-zinc kwaye linokumelana ne-corrosion, eliveliswa ikakhulu yinkqubo yokufaka i-galvanizing yediphu eshushu.Kwiminyaka yakutshanje, ngenxa yophuhliso olukhawulezayo lwezoqoqosho, imfuno yentsimbi yentsimbi kwimizi-mveliso yeemoto, ulwakhiwo, ukuvelisa, kunye nezixhobo zasekhaya iye yanda kakhulu.Amashiti afakwe igalvanized yenye yeentlobo zentsimbi ezikhula ngokukhawuleza e-China kwiminyaka yakutshanje.
Umaleko we-zinc weshiti lentsimbi editshiweyo linobungqingqwa obufanayo, ukuncamathela okuqinileyo, akukho kuxobuka ngexesha lokusetyenzwa, kunye nokunganyangeki kakuhle komhlwa.Umphezulu ugudile kwaye ucocekile, ubungakanani buchanekile, umphezulu webhodi uthe tye, i-spangles ilungile kwaye intle.
