Waraaqaha birta ah ee midabka leh waa alaab qotodheer oo laga sameeyay substrates (qabow-duuban/kulul-kulul galvanized ah oo aluminium-zinc ah oo dahaarka leh ama go'yaal aluminium) iyada oo loo marayo daaweynta dusha, dahaarka, iyo dubista. Waxaa si weyn loogu isticmaalaa baqshadaha dhismaha, darfaha qalabka guriga, gaadiidka, iyo meelaha kale. Tartankooda udub-dhexaadka ah waxay ku jiraan habka daahan (polyester PE, polyester-ka silikoon-la beddelay, SMP, fluorocarbon PVDF), saxnaanta substrate (sida tijaabada Jingye ee qafiifinta 0.35mm ee aadka u khafiifka ah), iyo waxqabadka deegaanka (daaha biyaha ku salaysan, VOC-yada hoose). Noocyada xaashida birta ah ee midabka leh ee hormuudka ka ah waxaa matala Baowu Steel, Shougang, Ansteel, iyo BlueScope, oo leh labadaba awoodda wax soo saarka, xoogga farsamada, iyo caymiska suuqa. Soosaarayaasha kale ee khaaska ah, sida Changzhou Jiaye, waxay soo saaraan biraha PCM iyo VCM, oo inta badan loo isticmaalo dhisidda baqshadaha, daboolka qalabka guriga, iyo codsiyada qurxinta sida hadhuudhka alwaax, camouflage, iyo qaababka dhagaxa. Hogaaminta birta isku dhafan ee birta ah: Baowu Steel (BAOWU): Kooxda ugu weyn ee birta ee Shiinaha, xaashideeda midabada leh waxay daboolaysaa noocyada buuxa ee PE, SMP, iyo PVDF, taageeraya dhumucda la habeeyey (0.35-1.0mm) iyo midabyo (shaxda midabka caadiga ah ee RAL). Shougang (SHOUGANG): Shirkadda Fortune Global 500, xaashideeda midabada leh ayaa loo isticmaalaa dhirta warshadaha, xarumaha kaydinta qabow, iwm, waxayna awood u leedahay inay soo saarto aluminium-zinc substrates (AZ150 ~ AZ200).
