Gloss & Color
Gloss Level: Full range adjustable: High Gloss (≥70°), Semi-Gloss (40-60°), Matt (≤30°).
Color Standards: Provides RAL, Pantone international standard color charts, and supports sample customization. Factory color difference is strictly controlled to ΔE ≤ 1.0, ensuring batch-to-batch consistency.
Backer Coating: Standard is a light-colored back paint providing basic protection; can be adjusted to oiled or untreated as needed.
Appearance Options
Wanzhi Group offers embossed, textured, and printed color coated aluminium coils for various fields like construction and home appliances, providing a wide range of aesthetic effects.
- Smooth Surface: Standard flat surface, suitable for most construction and appliance applications.
- Embossed/Relief Texture: Physical embossing creates three-dimensional patterns like orange peel, matte, leather grain, or diamond. This not only enhances aesthetics but also increases sheet rigidity and hides processing marks.
- Wood Grain/Stone Grain: Realistic simulated wood grain or stone grain embossing effects, suitable for high-end decoration.
- Printed Texture: Custom complex high-definition printed effects like wood grain, stone grain, brick wall, geometric patterns.
- Special Effects: Metallic paint (sparkles in sunlight), Hammered/Textured paint (unique artistic texture).
