Muuqaal ahaan, qaab-dhismeedkan malabka ah wuxuu ka kooban yahay unugyo aluminium ah oo ay ku jiraan zinc.Iyadoo daahan galvanized ay bixiso ilaalinta anodic, maadada zinc ee la dhimay iyo duubabka aluminiumka ayaa ka dhigaya mid u nugul koronto la'aan.Si kastaba ha ahaatee, tani waxay sidoo kale ka dhigan tahay in xaashida galvanized ay lumiso ilaalinteeda marka la gooyo, taasoo keenta miridhku geesaha la jaray.
Si loo xalliyo dhibaatadan, waxaa lagula talinayaa in lagu ilaaliyo cidhifyada rinjiga ama varnish-ka hodanka ah ee zinc, sidaas darteed sii dheereysa nolosha guddiga.Lakabkan ilaalintu waxa uu ilaaliyaa birta galvalume, isaga oo hubinaya nolosheeda adeegga iyo ilaalinta iska caabbinta daxalka aadka u fiican xitaa marka la eego xaaladaha jawiga ugu adag.
Daaweynta dusha sare: Daaweynta kiimikaad, saliid, qalalan, daawaynta kiimikaad iyo saliid, daabacaadda ka hortagga farta.

Birta Galvalume waxa ay leedahay sifooyin kala duwan oo ka duwan birta caadiga ah iyo dahaarka galvanized.Marka hore, waa qaabaysan oo waa la qaabayn karaa oo loo qaabayn karaa qaabab iyo naqshado kala duwan.Marka labaad, waa la iibin karaa, taas oo sahlaysa in la isku daro qaybo kala duwan si loo helo xiriir aan fiicneyn.Ugu dambeyntii, waa la rinjiyeeyay, taas oo u oggolaanaysa is-beddelka iyo codsiga midabyo kala duwan iyo dhamaystirid.
Alaabtan la taaban karo waxay leedahay adeegsiyo badan oo warshado kala duwan ah.Waxaa caadi ahaan loo isticmaalaa codsiyada saqafka iyo saqafka sababtoo ah caabbinta daxalka ee aad u fiican.Wax qabadkeeda aadka u wanaagsan oo ay weheliso wax-ku-oolnimada kharash-ku-oolnimada ayaa ka dhigaysa doorashada koowaad ee mashaariicda dhismaha ee deegaan iyo ganacsi.Intaa waxaa dheer, waxaa sidoo kale loo isticmaalaa soo saarista baabuurta, qalabka guryaha, qalabka beeraha iyo beeraha kale, oo sii muujinaya la qabsiga iyo isbedbeddelka.
Gabagabadii, birta galvalume waxay bixisaa xal u gaar ah caqabada ilaalinta daxalka.Waxay isku daraysaa aluminium, zinc iyo qaab dhismeedka malabka, kaas oo ka sarreeya daahan galvanized dhaqameed marka loo eego nolosha adeegga iyo iska caabinta miridhku.Nidaamkeeda, weldability iyo rinjiyeynta ayaa ka dhigaya mid ku habboon codsiyada kala duwan si loo hubiyo inay weli tahay doorashada koowaad ee warshadaha adduunka oo dhan.
Sida warshadaha alaabta biraha ee China keentay shirkadaha, ganacsiga birta qaranka iyo saadka "Boqol ganacsi iimaan wanaagsan", shirkadaha ganacsiga birta Shiinaha, "Top 100 shirkadaha gaarka loo leeyahay ee Shanghai". Shanghai Zhanzhi warshadaha Group Co., Ltd., (gaaban in Zhanzhi Group ) waxay qaadataa "Integrity, Practicity, Innovation, Win-Win" oo ah mabda'a hawlgalka kaliya, had iyo jeer waxay ku adkeystaan gelinta baahida macaamiisha meesha ugu horeysa.
