Xa izinto zetsimbi ezenziwe ngamagalvanized kufuneka zigcinwe kwaye zihanjiswe ngokusondeleyo, amanyathelo aneleyo okukhusela kufuneka athathwe ukukhusela ukugqwala. Amanyathelo athile othintelo ngala alandelayo:
1. Iindlela zonyango zomphezulu zingasetyenziselwa ukunciphisa ukubunjwa kwe-rust emhlophe kwi-coating.
Imibhobho ye-galvanized kunye nezixhobo ezingenanto ze-galvanized zingagqunywa ngoluhlu lwe-varnish ecacileyo emva kwe-galvanization. Iimveliso ezinje ngocingo, amashiti, kunye nemesh zinokuqatywa wax kwaye zifakwe i-oyile. Kumalungu olwakhiwo olwenziwa ngamazi ediphu ashushu, unyango lwe-chromium-free passivation lunokwenziwa ngoko nangoko emva kokupholisa amanzi. Ukuba iinxalenye ze-galvanized zingathuthwa kwaye zifakwe ngokukhawuleza, akukho mfuneko yonyango emva kokunyanga. Enyanisweni, ingaba unyango olungaphezulu luyafuneka kwi-hot-dip galvanizing ngokuyinhloko kuxhomekeke kwimilo yamalungu kunye neemeko ezinokuthi zigcinwe. Ukuba umphezulu we-galvanized uza kupeyintwa kwiinyanga ezintandathu, inkqubo efanelekileyo emva kokunyanga kufuneka ikhethwe ukuphepha ukuchaphazela ukunamathela phakathi kwe-zinc layer kunye nepeyinti.
2. Amacandelo e-galvanized kufuneka agcinwe kwindawo eyomileyo, enomoya ococekileyo kunye nokhuseleko olufanelekileyo.
Ukuba imibhobho yentsimbi kufuneka igcinwe ngaphandle, amacandelo kufuneka aphakanyiswe emhlabeni kwaye ahlulwe ngama-spacers amancinci ukuvumela ukuhamba komoya simahla kuyo yonke imiphezulu. Izixhobo kufuneka zithotywe ukuze kube lula ukukhupha amanzi. Akufunekanga zigcinwe kumhlaba omanzi okanye kwizityalo ezibolayo.
3. Iindawo ezigqunyiweyo zegalvanized akufuneki zibekwe kwindawo apho zinokuchanabeka kwimvula, inkungu, ukujiya, okanye ukunyibilika kwekhephu.
Niniintsimbi ekhandiweyoithuthwa ngolwandle, ayifanelanga ukuhanjiswa njengempahla okanye ibekwe kwindawo yokugcina inqanawa, apho inokudibana namanzi amdaka. Phantsi kweemeko zokuhlwa kwe-electrochemical, amanzi olwandle anokwenza umhlwa omhlophe ube mandundu. Kwiimekobume zaselwandle, ngakumbi kwiilwandlekazi ezitshisayo nezinomswakama ophezulu, ukubonelela ngemeko-bume eyomileyo kunye nezixhobo zokungenisa umoya ezifanelekileyo kubaluleke kakhulu.
