Gariiradda birta ah ee ppgi waxa kale oo loo magacaabay gariiradda birta galvanized ee hore loo diyaariyey (oo u gaaban “ppgi gariiradda”), waxa ay u isticmaashaa galvanized substrate ahaan.Ka dib daawaynta dusha sare (hoos u-dilista kiimikaad iyo daaweynta beddelka kiimikaad), dusha sare ee gariiradda birta ah ee ppgi ee lagu dahaadhay lakab ama dhowr lakab oo daahan ah, iyada oo loo marayo dubista iyo daawaynta, ka dibna noqo PPGI.Marka lagu daro ilaalinta lakabka zinc, daahan organic on lakabka zinc wuxuu door ka ciyaaraa daboolida iyo ilaalinta midabka birta ah ee dahaarka leh, ka hortagga gariiradda birta inay daxaloobaan, nolosheeda adeeguna waxay 1.5 jeer ka dheer tahay tan gariiradda birta galvanized.
Filimka rinjiga ah ee aan sameyn karno 10-30microns.Filimka rinjiga oo sarreeya, ayaa sii dheeraanaya nolosha adeegga midabka.
Qalabka rinjiyeynta waa PE, SMP, HDP, PVDF, iwm.
