Diyaarinta Substrate-ka iyo Samaynta Waraaqaha Biraha ah ee Midabka leh iyo Film-Clad: Xulashada Substrate: Substrates-ka loogu talagalay midabada-dahaarka leh iyo waraaqaha birta ah ee filimku waa sida caadiga ah xaashiyada birta ah ee qabow-duuban, xaashida kulul ee galvanized xaashida, xaashida aluminium zinc, zinc-aluminium-magnesium ee xaashida birta, xaashida aluminiumka, ama istaraatijiyad si toos ah u saameeya xaashida xoogga hoose ee birta. waxqabadka badeecada ugu dambeysa. Tusaale ahaan, halka birta xoogga badan ay leedahay awood sare, way adagtahay in la xakameeyo qaabka xaashida inta lagu jiro samaynta. Xakamaynta iyo Heerka: Birta birta ah ayaa marka hore daalacaysa gawaaruhu ka dibna waxa la simayaa heeriye si loo hubiyo in xaashidu fidsan tahay. Samaynta: Tani waa tillaabada muhiimka ah ee siinta xaashida midabka leh qaab gaar ah (sida xargaha, xargaha, xardho, iwm.). Xaashidu si joogto ah ayay qabow-u laablaabtaa iyada oo loo marayo xidhmo saxan oo samaysmaya. Iyada oo ku xidhan shuruudaha badeecada ugu dambeysa, xaashida mawjada-gacmeedka, go'yaal hir-sare ah, ama go'yaal qallafsan oo bir ah ayaa la soo saari karaa. Baasaska badan ee samaynta iyo xawaaraha farsamaynta oo gaabis ah, ayaa ka sii fiicnaanaya saxnaanta qaabka xaashida.
