Nubwo ibara ryo kubika ibintu ritose cyangwa 'ingese yera' bidakunze kwangiza ubushobozi bwo kurinda irangi rya galvanised, ni indwara yo mu maso yoroshye kwirinda.

Ikizinga cyo kubika ibintu gikozwe mu mazi kibaho iyo ibikoresho bishya bya galvanised bihuye n'ubushuhe nk'imvura, ikime cyangwa ubushuhe bwinshi (ubushuhe bwinshi), kandi bikaguma ahantu hatagera umwuka mwinshi ku buso. Ibi bishobora kugira ingaruka ku buryo patina irinda ikorwa.

Ubusanzwe, zinc ibanza gukorana na ogisijeni ikarema zinc oxide, hanyuma igakora ubushuhe bukarema zinc hydroxide. Iyo umwuka utemba neza, zinc hydroxide ihinduka zinc carbonate kugira ngo irinde zinc, bityo igabanye umuvuduko wayo wo kwangirika. Ariko, iyo zinc idafite umwuka utemba kandi igakomeza guhura n'ubushuhe, zinc hydroxide ikomeza gukura aho gukora ibara ryo kubika ibintu ritose.

Ingese z'umweru zishobora kuvuka mu byumweru cyangwa ndetse no mu ijoro ryose iyo ikirere kimeze neza. Mu bidukikije bikomeye byo ku nkombe, ikizinga cyo kubika amazi gishobora no guterwa n'imyunyu iri mu kirere ikomeza gukurura ubushuhe mu ijoro.

Ibyuma bimwe na bimwe bya galvanised bishobora kugira ubwoko bw'ikizinga cyo kubika ibintu kizwi nka 'black spotting', kigaragara nk'ibizinga byijimye bifite cyangwa bidafite ingese y'umweru. Ubu bwoko bw'ikizinga cyo kubika ibintu kigaragara cyane ku byuma byoroheje nk'amashuka, purlin n'ibice bifite ububobere buto. Biragoye cyane kubisukura kurusha ubwoko busanzwe bw'ingese y'umweru, kandi rimwe na rimwe ikizinga gishobora kugaragara nyuma yo gusukurwa.
