Brush aluminum composite panel is an Aluminum Composite Panel (ACP) or Aluminum Composite Material (ACM) where the outer aluminum skin has been treated with a brush finish (also called hairline finish or satin finish).

Key Components:

• Outer Aluminum Layers: Thin sheets of aluminum (typically 0.2mm to 0.5mm thick).

• Brush Finish: A mechanical polishing process using abrasive brushes or belts creates consistent, fine, unidirectional lines on the aluminum surface. This is usually done before the final protective coating is applied.

• Protective Coating: The brushed surface is almost always coated with a PVDF (Polyvinylidene Fluoride) or PE (Polyester) paint layer. This adds color, enhances UV resistance, and protects the brushed texture from corrosion and wear. Common colors include brushed aluminum (silver), brushed bronze, brushed gold, and brushed stainless steel looks.

• Core: A thermoplastic polyethylene (PE) or fire-resistant mineral core sandwiched between the two aluminum sheets, giving the panel rigidity and flatness.

Common Applications:

• Architectural Cladding & Facades: For a contemporary, sophisticated look on office buildings, retail spaces, and residential complexes.

• Interior Design: Feature walls, column covers, ceiling panels, and shop fittings.

• Signage & Branding: Used for upscale storefront signs and decorative letters.

• Furniture & Cabinetry: For modern kitchen panels, cabinet doors, and decorative trims.

Considerations:

• Directional Pattern: The brushing direction must be considered during design and installation. Panels should be installed with the grain running uniformly to maintain a consistent appearance.

• Not a True "Scratch-Hider": While it masks minor flaws, deep scratches perpendicular to the grain will be noticeable.

• Cleaning: Should be cleaned along the direction of the grain to avoid creating cross-scratches.
