Farqiga aasaasiga ah ee u dhexeeya xaashida aluminium-dahaarka leh ee midabka leh iyo xaashida birta caadiga ah waxay ku jiraan walxaha ay ka kooban yihiin, iska caabbinta daxalka, iyo xaaladaha codsiyada: Halabuurka walxaha: Go'yaal aluminium ah oo midabaysan ayaa laga soo saaray birta galvanized-aluminized (oo ka kooban 55% aluminium, 43% zinc, iyo 1.6% silicon). Substrate-yadan waxa lagu daweeyaa daawaynta chromate ka hor inta aan lagu dahaadhayn rinjiga dabiiciga ah oo la dubayo. Taas bedelkeeda, xaashida birta ee caadiga ah waxay caadi ahaan tixraacaan birta qabow-duuban ama birta galvanized, kuwaas oo aan midna ku jirin qayb aluminium ah. Iska caabinta Daxalka: Go'yaal aluminium aluminium ku dahaaran oo midab leh ayaa muujinaya iska caabbinta daxalka sare. Tusaale ahaan, xaashiyo bir ah oo galvanized-aluminis ah oo xoog-sare leh-sida darajooyinka AZ150 iyo G345A-waxay muujinayaan guurguurta karraaniga ee ka yar 2mm ka dib 1,000 saacadood ee soo-gaadhista 5% NaCl jawiga 35°C. Intaa waxaa dheer, waxay leeyihiin iska caabin cimilo oo heer sare ah, taasoo ka dhigaysa inay aad ugu habboon yihiin in lagu isticmaalo dhismayaal ama tas-hiilaadyo kale oo ku yaal xaalado deegaan oo aad u daran. Muuqaallada Codsiga: Go'yaal aluminium ah oo midabaysan ayaa ku habboon dhismayaal ama tas-hiilaadyo ay dalabaadka sare ku dhejiyaan iska caabinta daxalka iyo iska caabinta cimilada. Taa beddelkeeda, xaashiyaha birta ee caadiga ah ayaa laga yaabaa inay ku habboon yihiin codsiyada leh shuruudaha adag ee ku saabsan guryahan - sida caqabadaha ku-meel-gaarka ah ama qalabka dhismaha gudaha.
