Go'yaal aluminium-dahaarka leh ayaa ka sarreeya birta galvanized ee dhinacyada qaarkood. I. Waraaqaha aluminium-dahaarka leh vs. Galvanized Waraaqaha aluminiumka iyo galvanization labadaba waa tignoolajiyada daaweynta dusha birta; waxay wanaajiyaan iska caabinta daxalka iyo sifooyinka kale iyagoo isticmaalaya lakab ilaalin ah - aluminium ama zinc, siday u kala horreeyaan - dusha birta. Mid kasta oo ka mid ah tignoolajiyadaasi waxay leedahay faa'iidooyin kala duwan, iyo doorashada taas oo ka sareysa waxay ku xiran tahay shuruudaha codsiga gaarka ah iyo macnaha guud. II. Astaamaha iyo Faa'iidooyinka Waraaqaha Aluminium-dahaarka leh ee aluminium-dahaarka leh ayaa caan ku ah iska caabbinta daxalka ee wanaagsan, milicsiga kulaylka sare, iyo caabbinta sare ee wasakhda. Waxay muujiyaan iska caabin xooggan oo ay ka mid yihiin shucaaca ultraviolet iyo daxalka kiimikada, taasoo ka dhigaysa in si weyn looga faa'iidaysto qaybaha ay ka mid yihiin dhismaha, soo saarista baabuurta, iyo qalabka guriga. Intaa waxaa dheer, xaashida aluminium-dahaarka leh waxay leeyihiin kuleyl kuleyl heer sare ah, taasoo horseedaysa codsigooda ballaaran ee meelaha sida kuleyliyeyaasha. III. Astaamaha iyo Faa'iidooyinka Waraaqaha Galvanized Waraaqaha Galvanized, taa lidkeeda, waxaa lagu door bidaa iska caabin daxalka adag, qiime jaban, iyo baaxadda codsiga. Dahaarka Zinc ee lagu dabaqo dusha sare ee xaashida galvanized waxay bixisaa ilaalin wax ku ool ah, taas oo u oggolaanaysa inay sii wadaan waxqabadka wanaagsan xitaa jawiga qoyan. Waxay si weyn uga shaqeeyaan warshadaha kala duwan.
