Substrate-ka gariiradda leben-cas midabka-dahaarka leh waa faliiq bir ah; Noocyada caadiga ah waxaa ka mid ah xaashida qabow-duuban, xaashida galvanized-ku-kulul, xaashida kulul ee Al-Zn ee dahaarka leh, iyo xaashi-galvanized electro-galvanized. Substrate-yadani waxay leeyihiin awood qaabdhismeed oo wanaagsan waxayna bixiyaan iska caabin miridhku aasaasi ah oo ay dahaarkooda u maraan. Dusha sare (Dahaadhka casaan-buluugga): Nooca caadiga ah: Polyester-ka caadiga ah (PE); waxay bixisaa qiimo jaban iyo taran midab wanaagsan, oo ku habboon codsiyada guud. Nooca cimilada u adkaysta: Silicone-Modified Polyester (SMP) — inta badan ganacsi ahaan la heli karo gariiradaha birta ku dahaaran leben-cas waxay ku dhacaan qaybtan; Waxay bixisaa iska caabin cimilo oo ka wanaagsan polyester-ka caadiga ah, oo ku habboon isticmaalka dhismaha bannaanka. Waxa kale oo ka mid ah Polyester-Durability High (HDP), kaas oo bixiya adkeysiga dheeraadka ah. Nooca adkeysiga sare: Fluorocarbon (PVDF); waxay leedahay cimilo gaar ah iyo iska caabin daxalka leh oo leh nolol adeeg dibadeed oo ah 15-20 sano, taasoo ka dhigaysa doorashada ugu sareysa mashaariicda dibadda ee dhamaadka-sare.
