Dahaarka dusha sare ee xaashidan galvanized wuxuu ka kooban yahay 55% aluminium, 43.5% zinc iyo qadar yar oo walxo kale ah.Marka lagu eego mikroskoob, dusha dahaarka ayaa ka dhigaya qaab dhismeed malabka, aluminium aluminiumka ah waxaa ku jira zinc.
Iyadoo dahaarka galvanized ay bixiyaan ilaalinta anodic, waxaa jira xaddidaadyo gaar ah.Iyada oo la yareeyey maadada zinc iyo ku duubidda aluminiumka agagaarka maaddada zinc, electrolysis wuxuu noqonayaa mid yar.Si kastaba ha ahaatee, tani waxay sidoo kale ka dhigan tahay in marka xaashida galvanized la gooyo, lakabka difaaca ayaa dhaawacmi doona, iyo cidhifka goynta ayaa u nugul miridhku.Si loo kordhiyo nolosha adeegga saxanka, waxaa lagula talinayaa in la yareeyo goynta oo la qaado tallaabooyinka ka hortagga miridhku, sida rinjiyeynta rinjiga ka hortagga miridhku ama rinjiga zinc-hodanka ah.
Daaweynta dusha sare: Daaweynta kiimikaad, saliid, qalalan, daawaynta kiimikaad iyo saliid, daabacaadda ka hortagga farta.

Haddaba, aynu u dhaadhacno sifooyinka birta galvalume.Waxay ka kooban tahay 55% aluminium, 43.5% zinc iyo 1.5% silicon.Halabuurkani wuxuu ka dhigayaa mid sahlan in la sameeyo, alxanka iyo rinjiga, taas oo ka dhigaysa mid aad u badan oo loogu talagalay codsiyada kala duwan.Intaa waxaa dheer, isku darka ilaalinta allabari ee zinc iyo ilaalinta aluminiumka ilaalinteeda waxay keenaysaa iska caabbinta daxalka oo aad u fiican xitaa xaaladaha jawiga ugu adag.Dhab ahaantii, iska caabbinta daxalka ee birta galvalume waa 2-6 jeer ka sarreeya tan daahan birta galvanized kulul.
Gebogebadii, gariiraddayada birta galvalume waa isku dhafka ugu fiican ee xoogga, kala duwanaanshaha iyo iska caabinta daxalka.Iyada oo ay ka kooban tahay halabuurka gaarka ah iyo sifooyinka wanaagsan, waxay ka sarreysaa birta galvanized ee caadiga ah marka loo eego cimri dhererka, taas oo ka dhigaysa mid ku habboon codsiyada kala duwan.Aamin birta galvalume si ay u bixiso ilaalin waarta, oo la isku halayn karo mashaariicdaada.
Sababo la xiriira astaamihiisa aadka u wanaagsan, birta galvalume waa shay caan ka ah warshado badan.Waxaa si weyn loogu isticmaalaa dhismaha iyo qaabeynteeda waxay u oggolaaneysaa naqshado adag iyadoo la ilaalinayo sharafta qaabdhismeedka.Waa doorasho aad u fiican oo loogu talagalay codsiyada saqafka iyo derbiga, iyada oo bixisa cimri dherer iyo cimri dheer oo aan isbarbardhigin.Intaa waxaa dheer, iyada oo ay ugu wacan tahay caabbinta daxalka ee aadka u wanaagsan iyo awoodda ay u adkeyso jawiga adag, birta galvalume waxaa si weyn loogu isticmaalaa wax soo saarka baabuurta, qalabka korontada iyo mashiinada beeraha.
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.
