Production Process of Wavy PPGL Sheets
- Raw Material Preparation: Adopt qualified hot-dip galvalume steel coils as the base substrate.
- Surface Pretreatment: Remove oil, dust and oxide layers through cleaning and chemical passivation to improve paint adhesion and corrosion resistance.
- Continuous Color Coating & Curing: Apply primer, topcoat and backcoat with PE/SMP/HDP/PVDF paint systems, and cure under high temperature to form a stable organic coating layer.
- Leveling & Straightening: Straighten the coated steel coil to ensure flatness and consistent mechanical performance.
- Cold Roll Forming: Process flat PPGL strips into standard corrugated/wavy profiles by professional roll forming machines without damaging the paint surface.
- Precision Cutting: Cut wavy sheets into customized lengths via controlled hydraulic cutting system.
- Final Inspection & Packaging: Check size, surface quality and flatness, then pack with protective film and export standard bundles.
