Aluminium-dahaarka midabka leh ee albaabbada iyo daaqadaha asal ahaan waa badeecad isku dhafan oo la sameeyay iyada oo la isku darayo substrate alloy aluminium tayo sare leh oo leh lakabyo badan oo daahan oo shaqeynaya oo sax ah khadka soo saarista joogtada ah. Substrate: aluminium aluminium aluminium profiles albaabada iyo daaqadaha waxay u baahan yihiin xoog gaar ah iyo karti shaqo; Qalabka sida caadiga ah loo doortay waa: Fasalada Alloy: Ugu horreyntii 3000-taxane ah (tusaale, 3003, 3004; oo ay ku jiraan manganese si loogu adkaysto daxalka sare) ama 5000-taxane (tusaale, 5005; oo ka kooban magnesium xoog sare) aluminium-magnesium-manganese gariiradda aluminium. Xanaaqa: Caadi ahaan H14 ama H24 (semi-adag) xanaaq, hubinta qaabdhismeed ku filan qaloocinta iyo hawlgallada shaabadeynta xiga iyadoo laga hortagayo jab jaban. Codsiga Muhiimka ah ee Deegaanka Goobaha Shucaaca UV ee Sare: Meelaha sare ama loolka hoose ee leh iftiinka qorraxdu, rinjiyada caadiga ah waxay u nugul yihiin inay dhalaalayaan oo ay libdhaan. Dahaarka Fluorocarbon (PVDF), oo leh xirmooyin kiimikaad oo xooggan, waxay iska caabin karaan xaalufka UV muddo dheer, iyagoo ilaalinaya midabka asalka ah ee albaabbada iyo daaqadaha. Wasakhowga Wershadaha iyo Goobaha Aashitada: Meelaha ku xeeran dhirta kiimikada ama magaalooyinka leh wasakhowga hawada daran, sulfur dioxide iyo nitrogen oxides ee jawiga ku jira waxay samayn karaan roob aashito ah. Dahaarka cufan ee dusha sare ee aluminium-dahaarka leh ayaa leh caabbinta aashitada iyo alkali aad u xooggan, isaga oo ka ilaalinaya substrate-ka daxalka.
