Iyada oo ku saleysan 55% Al-Zn alloy (Galvalume) substrate dahaarka ah, iska caabbinta daxalka waa 2-6 jeer ka birta galvanized saafi ah. Marka lagu daro jaakad sare oo cimilo adkaysi u leh oo khamri-cas-cas ah oo tayo sare leh, waxay bixisaa nolol naqshadayn ka badan 30 sano oo loogu talagalay codsiyada dibadda sida saqafka iyo daboolka, oo leh kharash dayactir yar. Dahaarka Al-Zn iyo jaakad midab khafiif ah (tusaale, khamri-cas) ayaa wada shaqeeya si ay u bixiyaan Tusaha Milicsiga Qorraxda ee Sare (SRI), oo si wax ku ool ah u muujinaya kulaylka infrared. Tani waxay kaa caawinaysaa in ay hoos u dhigto heerkulka dusha sare ee dhismaha waxayna yaraynaysaa isticmaalka tamarta qaboojiyaha, gaar ahaan ku habboon dhismayaasha tamarta wanaagsan ee cimilada kulul. Koodhka sare ee cas-khamriga ayaa isticmaala polyester-ka cimilada u adkaysta ama nidaamyada fluorocarbon oo leh nuugayaasha UV ee gaarka ah. Waxay ilaalinaysaa midab firfircoon muddo dheer oo leh tamaashiir aad u fiican oo iska caabin ah, iyada oo hubinaysa bilicda dhismaha ee waarta si ay u buuxiso shuruudaha bilicda iyo waxqabadka ee dhamaadka-sare ee mashaariicda ganacsiga iyo deegaanka.
