Codsiyada daaqadaha birta ah ee alwaax-laba-geeska ah ee alwaaxyada qurxinta leh ee alwaaxyada birta ah ee labajibbaaran waa nooc cusub oo walxaha qurxinta ah oo isku daraya qurxinta dabiiciga ah iyo waxqabadka sare. Waxaa si weyn loogu isticmaalaa qurxinta gudaha iyo dibadda ee dhismaha, gaar ahaan ku habboon xaaladaha leh shuruudaha sare ee texture, adkeysiga, iyo caabbinta dabka. Waraaqda birta ah waxay noqon kartaa birta galvanized, birta aluminium ee zinc, birta zinc-aluminium-magnesium, aluminium-magnesium-zinc birta, aluminium, ama birta aan lahayn. Doorashada substrate-ka waxay ku xiran tahay xaaladda lagu dabaqi karo, nolosha adeegga, iyo kharashka miisaaniyadda. Astaamaha Muhiimka ah Dhamaystir laba-dhinac ah, naqshad dabacsan: Labada dhinacba waxaa lagu daboolay filim alwaax ah oo heersare ah, taageeraya isticmaalka laba-geesoodka ah ama rakibaadda, hagaajinta isticmaalka walxaha oo ku habboon qaababka dib loo rogi karo ama naqshadaha qaybaha bannaanka ah. Substrate-ka xasiloon, qallooc u adkaysta: Caadi ahaan ku salaysan aluminium-cag-caag ah oo isku dhafan, aluminium hal panels, ama birta galvanized, waxay leeyihiin xoog wanaagsan iyo xasillooni cabbir ah, uma nugulna inay dillaacaan ama ku dagaallamaan degaannada koonfureed ee qoyan ama jawiga heerkulka sare ee gobollada waqooyiga.
