Orange Peel PPGI coils feature a special surface effect that serves as a decorative element and increases surface friction. Orange Peel is a special coating that mimics the uneven texture of citrus fruit peels, a type of textured PPGI coil that falls between glossy and rough. Options include subtle, standard, and heavy orange peel, depending on the degree of roughness.

Orange Peel Process
- Substrate Preparation: First, degrease and clean the galvanized steel coil. Then, a chemical conversion coating is formed on the surface through a chromium-free passivation or chromization treatment.
- Primer Application: Select epoxy resin (EP), polyurethane, or polyester as the coating. Roll-coat a 5-20 micron thick film on the galvanized steel surface.
- Topcoat Application – Orange Peel Formation: Select a functional paint such as polyester, fluorocarbon, or highly weather-resistant polyester as the topcoat. Use a micro-dimpled textured roller to apply one or more layers of the textured coating to the steel surface.
- Texture Curing: High-temperature heating is used to cure the texture.
- Cooling: The cured PPGI steel is cooled by air quenching and then used.
- Coiling: The coil is stored and shipped.
Orange Peel PPGI Coil Advantages
- Scratch Concealment: The orange peel texture scatters light, making minor scratches imperceptible to the naked eye. It also shields against transportation scrapes and is abrasion-resistant and scratch-resistant.
- Fingerprint Resistance: The textured surface reduces hand contact, making it less likely to leave marks. Improved coating adhesion: The roughened surface area increases by 20-30%, enhancing the mechanical bond between the coating and the substrate.
- Optical comfort: Low reflection, reduced glare, suitable for bright light environments.
- High thickness tolerance: The convex and concave surface can mask minor substrate unevenness or coating thickness fluctuations (±3μm).
- Aesthetics: The textured surface of PPGI creates a commercial look and offers excellent decorative appeal.
- Corrosion resistance: Metal coatings and colored paint coatings provide corrosion protection.
Orange Peel PPGI Coil Applications
- Home Appliances: Side panels for high-end appliances, air conditioner casings
- Building Interiors: Exterior walls, roofs, billboards, interior ceilings, elevator cars, partitions
- Office Furniture: File cabinets, conference desk panels
- Industrial Equipment: Control cabinets, instrument casings
- Transportation: Vehicle panels, carriage panels, subway interior panels, luggage racks
- Logistics Containers: Refrigerated equipment
