1. Prepainted Steel Coil kouvwi ak kouch òganik, ki bay pi wo pwopriyete anti-korozyon ak yon lavi ki pi long pase sa yo ki nan fèy asye galvanised.
2. Metal debaz yo pou Prepainted Steel Coil konpoze de woule frèt, HDG elektwo-galvanize ak cho-tranpe alu-zenk kouvwi asye.Rad yo fini nan Prepainted Steel Coil ka klase an gwoup jan sa a: Polyester, Silisyòm modifye Polyester, fliyò polyvinylidene, segondè-durabilite Polyester, elatriye.
3. Pwosesis pwodiksyon an te evolye soti nan yon sèl-kouvwi-ak-yon sèl-boulanjri nan doub-kouvwi-ak-double-boulans, e menm twa-kouvwi-ak-twa-boulanjri.
