Halabuurka Substrate Substrate-ka birta ah ee loo isticmaalo alaabtan ayaa ah sida caadiga ah birta galvanized-kululeed (GI) ama birta dahaarka leh ee aluminium-zinc (GL). Qiyaasaha substrate gaar ah (sida heerka birta iyo xoogga dhalidda) iyo miisaanka dahaarka (tusaale, Z275 ama AZ150) ayaa horay u cayimay iibsadaha oo ku salaysan shuruudaha iska caabinta daxalka ee deegaanka isticmaalka dhamaadka. Kahor habka dahaarka, substrate-ku wuxuu horey u lahaadaa dahaarka aasaasiga ah ee ka-hortagga daxalka. Nidaamka Dahaarka Nidaamka daahan guud ahaan wuxuu ka kooban yahay lakabka hore iyo lakabka sare ee koodhka, samaynta qaab-dhismeedka "laba jaakad": Nidaamka Resin: Dusha sare waxay caadi ahaan isticmaashaa polyester (PE) resin, ama polyurethane (PU) nidaamyada resin ee codsiyada u baahan iska caabbinta cimilada sare. Resins-yadani waxay bixiyaan sifooyin heer sare ah iyo kala firdhisanaanta midabka. Waxqabadyada Waxqabadka: Si loo gaaro matte ( dhalaal yar) iyo "laalaabkii" ama "diirka oranji", samaynta koodhka sare wuxuu ku daraa qaybo gaar ah oo ah wakiilada gogosha, wakiilada heerka, iyo waxyaabaha lagu daro si looga hortago cilladaha sida jeexjeexyada ama duuduubka aan la rabin. Inta lagu jiro habka daawaynta firfircoon, waxyaalahan lagu daro waxay beddelaan xiisadda dusha sare ee filimka, taasoo keenta hoos u dhac aan caadi ahayn oo yar oo keenaya dhammaystir aan caadi ahayn, dhammays muuqaal ah.
