Miisaanka yar-yar, qaab-dhismeedkan malabka ah wuxuu bixiyaa ilaalin anodic ah oo aad u fiican, laakiin iyadoo la yareeyey maadada zinc iyo walxaha zinc ee lagu daboolay aluminium, khatarta korantada waa la yareeyaa.Si kastaba ha ahaatee, tani waxay sidoo kale ka dhigan tahay in marka xaashida galvanized la gooyo, geesaha la gooyay lama ilaalin oo miridhku wuu kobcin karaa.Si loo xalliyo dhibaatadan, waxaa lagama maarmaan ah in la yareeyo goynta oo lagu dabaqo rinjiga ka hortagga miridhku ama rinjiga zinc-ka ah si loo ilaaliyo cidhifyada loona dheereeyo nolosha adeegga guddiga.
Daaweynta dusha sare: Daaweynta kiimikaad, saliid, qalalan, daawaynta kiimikaad iyo saliid, daabacaadda ka hortagga farta.

Mid ka mid ah sifooyinka muuqda ee Galvalume Steel-kayaga waa iska caabbinta daxalka ee wanaagsan.Ilaalinta allabariga ee zinc iyo ilaalinta xannibaadaha aluminiumku waxay isku daraan waaritaan sare xitaa xaaladaha jawiga ugu daran.Dhab ahaantii, daahannadayada birta galvalume waxay qabtaan 2-6 jeer ka wanaagsan daahannada galvanized marka la barbar dhigo birta galvanized-kuleelka kulul.Tani waxay ka dhigan tahay alaabadayadu waxay bixiyaan ilaalin sare iyo nolol dheer, siinaya macaamiisheena nabada maskaxda.
Kala duwanaanshaha gariiradayada GL ayaa ka dhigaysa inay ku habboon yihiin codsiyo kala duwan.Laga soo bilaabo saqafka iyo dhejiska ilaa baabuurta iyo dhismaha, birtayada galvalume waa doorashada la aamini karo ee mashaariicda u baahan iska caabin daxalka heersare ah, qaabaynta, alxanka iyo rinjiyeynta.Haddi aad tahay naqshadeeye, injineer ama dhisme, gariiradayada GL waxay dabooli karaan baahiyahaaga gaarka ah waxayna dhaafi karaan filashadaada.
Gebogebadii, gariiraddayada GL ama gariiradaha birta ee galvalume waxay isku daraan sifooyinka ugu fiican ee qalabka galvanized iyo aluminium.Iyada oo ay ka kooban tahay mid gaar ah, iska caabin daxalka aadka u fiican iyo isugeynta aan la barbar dhigi karin, waa doorashada ugu fiican ee codsiyada kala duwan.Ku kalsoonow birtayada galvalume si ay ku siiso waxqabad heersare ah, adkeysi iyo bilicsanaan.
