Ngelixa ibala lokugcina elimanzi okanye 'umhlwa omhlophe' kunqabile ukuba kuphazamisane nesakhono sokukhusela sengubo eyenziwe ngegalvanized, bubukhazikhazi bobuhle ekulula ukuluphepha.

Ibala logcino olumanzi lwenzeka xa izinto ezisandul’ ukugalelwa amazimba zisesichengeni sokufuma okufana nemvula, umbethe okanye ukujiya (ukufuma okuphezulu), kwaye zihlale kwindawo enomoya omncinci ohamba phezu komhlaba.Ezi meko zinokuchaphazela indlela i-patina ekhuselayo eyenziwa ngayo.

Ngokuqhelekileyo, i-zinc isabela kuqala ngeoksijini ukuze yenze i-zinc oxide, kwaye ngokufuma yenze i-zinc hydroxide.Ngokuhamba komoya kakuhle, i-zinc hydroxide iguqukela kwi-zinc carbonate ukubonelela ngokhuseleko lomqobo kwi-zinc, ngaloo ndlela icothisa isantya sokubola kwayo.Nangona kunjalo, ukuba i-zinc ayinakho ukufikelela kumoya ohamba ngokukhululekileyo kwaye ihlala ibonakaliswe kumswakama, i-zinc hydroxide iyaqhubeka nokuphuhlisa endaweni kwaye yenza ibala lokugcina elimanzi.

Umhlwa omhlophe unokuvela kwiiveki okanye ubusuku bonke ukuba iimeko zilungile.Kwiimeko ezimandundu ezingqonge unxweme, ibala lokugcina elimanzi linokuthi libekho kwiidiphozithi ezakhiweyo ezifumaneka emoyeni ezifunxa ukufuma ebusuku.

Enye intsimbi ekhandisiweyo ingaphuhlisa uhlobo logcino olumanzi olwaziwa ngokuba 'yindawo emnyama', ebonakala njengamachokoza amnyama anerusa emhlophe ejikelezileyo.Olu hlobo logcino olumanzi luxhaphake kakhulu kwintsimbi yokulinganisa ukukhanya njengamaphepha, ii-purlins kunye namacandelo angenanto abhityileyo.Kunzima kakhulu ukucoceka kuneendlela eziqhelekileyo zomhlwa omhlophe, kwaye ngamanye amaxesha indawo isenokubonakala emva kokucoca.
