Overview


Designed for eye-catching signage and display applications, our Black Sandwich Sign Board Aluminum Composite Panels feature a striking matte or gloss black finish, perfect for creating bold, professional visuals. The sandwich structure—consisting of two aluminum skins and a polyethylene core—offers a lightweight yet rigid substrate for digital printing, vinyl wrapping, or direct graphic application.


Features


Deep Black Aesthetics: The uniform black color provides an ideal backdrop for vibrant graphics, ensuring high contrast and visual impact in billboards, storefront signs, and vehicle wraps.

Printing Compatibility: The smooth surface accepts all major printing technologies—UV, solvent, and latex—without ink bleeding or texture interference.

Impact Resistance: The core absorbs minor impacts, preventing dents and cracks that could damage signage, even in high-traffic areas.

Lightweight Design: At just 3-4 kg per square meter, these panels are easy to handle and install on poles, walls, or suspended frames.

Weatherproof Finish: The black coatings are UV-stabilized to resist fading, ensuring long-lasting color intensity for outdoor signage.


Application


Outdoor Billboards: Ideal for large-scale advertising where durability and visual appeal are key, even in sunny or rainy climates.

Storefront Signage: Used for backlit or non-illuminated signs, providing a sleek, modern base for logos and brand messaging.

Vehicle Wraps: Lightweight and conformable, they adapt to curved surfaces of cars, trucks, and buses for mobile advertising.

Interior Displays: Suitable for exhibition booths, trade show panels, and retail decorations, offering a professional black canvas for graphics.


FAQ


Q: Can the black surface be used for backlit signs?

A: Yes, the matte finish diffuses light evenly for backlit applications, while the gloss finish enhances brightness in front-lit signs.

Q: How thick are these panels?

A: Standard thicknesses are 3mm, 4mm, and 6mm, with 4mm being the most popular for signage.

Q: Do they require a protective laminate for printing?

A: A laminate is recommended for outdoor applications to enhance scratch resistance and extend print lifespan, though not mandatory for short-term use.
