Unyango olungaphezulu lusetyenziselwa ukuveliswa kwentsimbi ipleyiti. Intsimbiipleyiti ifakwe kwisisombululo se-chromic acid ukwenza ifilimu encinci kumphezulu we-zinc layer. Nangona ifilimu ye-chromate iphukile kancinci, i-chromate kwindawo ekufutshane nekhefu iya kuchithwa emanzini kwaye iqokelele kwikhefu kwaye iphinde ifake ifilimu entsha. Oku kuthintela ukuveliswa komhlwa omhlophe. Faka ioli kwintsimbi ye-galvanizedipleyiti ukuthintela ukudibana ngqo phakathi komoya kunye ne-zinc. Ngalo lonke ixesha qaphela ukuba ioli kufuneka icinywe kumphezulu wentsimbiipleyiti ngaphambi kokupeyinta. Ukuba intsimbiipleyiti izakusetyenziselwa iinjongo zokupeyinta, inokunyangwa ngesikhumba esityileyo. I-*ed iya kubambelela ngokuthe gqolo kumphezulu wentsimbiipleyiti, ukwenza indawo ekhululekileyo, edibeneyo eya kunika indawo efanelekileyo yokuba ipeyinti ibambelele.

Intsimbi yegalvanized ipleyiti kufuneka igcinwe kwindawo enomoya owaneleyo emva kwemveliso. Okanye sebenzisa isomisi okanye i-oven yokomisa ukunqanda ukujiya ngexesha lokufuma okuphezulu kunye nomahluko omkhulu phakathi kokubanda nokufudumala. Ngeli xesha i-Wan ayinakumanzi ngokuntywiliselwa. Ukuba imanziswe ngumbethe okanye ngamanzi, ifanele yomiswe, yaye ipakethe inokohlwaywa ize ivuthelwe yomiswe kusetyenziswa ifeni. Igcinwe kwindawo engena umoya, ukuba umahluko lobushushu phakathi kubanda kunye nokufudumala, lula ukuba kwenzeke apho umbethe kufuneka kuphetshwe.

(1) Intsimbi engatyiwayo ipleyiti ukwenza unyango olungaphezulu, olufana nokuvumela umphezulu wayo ukuba wenze ifilimu ebhityileyo, ngaloo ndlela, ukwenza i-porous structure ekhululekileyo, ukugudisa umphezulu womsebenzi wokutshiza ipeyinti.

(2)Beka intsimbi engenasici ipleyiti kwindawo epholileyo kunye nomoya, thintela umswakama kunye nemvula, ukuba kuyimfuneko, ezinye iindlela zokukhusela umphezulu zingathathwa.
