Dahaarka dusha sare ee gariiradda birta galvanized waxay leedahay qaab dhismeed malabka gaar ah.Muuqaal ahaan, dahaarku wuxuu ka kooban yahay aluminium "alaabooyinka malabka" oo ay ku jiraan zinc.Naqshad xariif ah kaliya ma bixiso ilaalinta anodic laakiin sidoo kale waxay yaraynaysaa fursada elektrolysiska sababtoo ah aluminiumka oo soo koobaya walxaha zinc.Si kastaba ha ahaatee, waxaa muhiim ah in la ogaado in jarista galvalume ay keeni karto hoos u dhac ku yimaada awoodeeda ilaalinta anodic.Sidaa darteed, waxaa lagula talinayaa in la yareeyo goynta iyo ilaalinta cidhifyada tallaabooyinka ka hortagga miridhku sida rinjiga ama rinjiga zinc-ka si loo kordhiyo nolosha adeegga saxanka.
Daaweynta dusha sare: Daaweynta kiimikaad, saliid, qalalan, daawaynta kiimikaad iyo saliid, daabacaadda ka hortagga farta.

Gariiradda Galvalume waa alaabo tignoolajiyadeed horumarsan oo shaqaynaysa oo leh iska caabin daxalka oo aad u wanaagsan, qaabayn, alxan iyo rinji.Halabuurka gaarka ah wuxuu isku daraa aluminium, zinc iyo silicon si ay u bixiso heer sare oo miridhku iyo ilaalinta oksaydhka, taas oo ka dhigaysa doorashada koowaad ee codsiyada kala duwan.Hadday tahay dhismaha, wax soo saarka ama isticmaalka baabuurta, Galvalume Coil waxay hubisaa isku halaynta iyo nolosha adeegga ee ka sarreysa heerarka warshadaha iyo waxyaabaha laga filayo.Dooro Gariiradda Galvalume si aad u hesho waxqabad heersare ah iyo adkeysi
Mid ka mid ah faa'iidooyinka ugu muhiimsan ee birta galvalume waa qaabaynta aad u fiican, alxanka iyo rinjiyeynta.Dabacsanaantani waxay u oggolaanaysaa in si fudud loo beddelo lana waafajiyo shuruudaha mashruuca ee kala duwan.Intaa waxaa dheer, iyadoo ay ugu wacan tahay isku dhafka ilaalinta allabariga ee zinc iyo ilaalinta xannibaadda aluminiumka, birta galvalume waxay leedahay iska caabin heer sare ah oo daxalka hoos yimaada xaalado kala duwan oo jawiga.Dhab ahaantii, marka la barbar dhigo birta galvanized kulul-muquufin, daahan galvalume 2-6 jeer ka wanaagsan dahaarka galvanized caadiga ah.
Marka laga eego aragtida kala soocida, gariiradaha birta galvanized waxay ka tirsan yihiin qaybta birta waxqabadka sare leh.Waxay la kulmeysaa oo dhaaftay heerarka ay dejisay warshaduhu, taasoo ka dhigaysa doorasho la isku halayn karo oo la aamini karo xagga dhismaha, wax soo saarka, baabuurta iyo codsiyada kale ee dalbanaya.Gariirada galvalume-kayaga ayaa lagu heli karaa cabbirro kala duwan si loo daboolo baahiyaha gaarka ah ee mashaariicda kala duwan, hubinta waxqabadka wanaagsan iyo cimri dhererka.
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.
