Xaashiyaha birta ah ee dahaadhka ah ee alwaaxdu waa walxo isku dhafan oo laba-lakab ah oo ay sameeyeen kuleyl ahaan isku xira "substrate bir ah" oo leh "filim qurxinta polymeric." Qaab dhismeedkan, qaybta birta ahi waxay bixisaa xoog iyo adkaysi, halka lakabka la dhejiyay uu bixiyaa bilicsanaanta alwaax-hadhuudhka dhabta ah oo ay weheliso sifooyin ilaalin shaqaynaya. Lakabka hoose ee xaashida hadhuudhka ah ee birta dahaadhay waxay u adeegtaa sidii qaybta culayska iyo taageerada qaabdhismeedka. Qalabka substrate-ka caadiga ah waxaa ka mid ah: Aluminium Sheet (Inta badan): Sida 3003, 5052, iyo 6063 aluminium aluminium-oo lagu garto miisaankooda fudud, caabbinta daxalka, iyo fududaynta habaynta-kuwaas oo si weyn loogu isticmaalo gidaarka gudaha iyo saqafka. Sheet-ka-soo-baxa ah: Sida darajooyinka 304 iyo 201- haysashada iska caabbinta daxalka xooggan iyo guryaha antimicrobial-kuwaas oo inta badan laga shaqeeyo jawi nadaafadeed oo sarreeya, sida isbitaallada iyo jikada. Galvanized Steel Sheet / Midab-Dahaaran Steel Sheet: Lagu garto kharashyo hoose, kuwani waxay u baahan yihiin ka-hortag beddelaad kiimiko oo dusha sare ah si kor loogu qaado ku dheggan lakabka filimka la dahaaray. Gudida Malabka Aluminium / Aluminium Composite Panel: Waxaa loo isticmaalaa meelaha mashruuca ee heerarka sare looga baahan yahay ee ku saabsan flatness, dahaarka dhawaaqa, ama caabbinta dabka.
