Painted Aluminum Trim Coil

Painted aluminum trim coils are decorative and protective materials made from aluminum alloy with a coated surface. They offer a wide range of colors and excellent weather resistance. Trim coils are a type of aluminum material used in construction and decoration, typically for trimming edges and corners in buildings, such as eaves, door and window frames, cornices, and wall trim, serving to beautify the appearance and protect the building structure.

Common aluminum alloys of painted aluminum trim coil including AA3003 and AA3105, which have good corrosion resistance and processing performance. They come in various specifications, with thicknesses ranging from 0.018 to 0.032 inches (0.46 to 0.81 mm), and widths and lengths can be customized according to customer needs. Common sizes include 24 inches × 50 feet.

The commonly used surface treatment process of painted aluminum trim coil is color coating, which is environmentally friendly and offers excellent coating performance. Color coatings can be formulated in various colors and with special effects, exhibiting strong adhesion, high corrosion resistance, wear and impact resistance, and a uniform surface free from defects such as runs and orange peel.

Coating effects for aluminum trim coil:

Protective properties: The coating isolates moisture, salt spray, and contaminants, extending its service life (10-20 years outdoors).

Decorative properties: Supports a variety of colors (e.g., standard white, royal brown, dark bronze, black) and surface finishes (matte, high gloss, metallic) to meet architectural aesthetic needs.

Functionality: Some coatings possess antistatic, self-cleaning, or antibacterial properties, suitable for special applications.

Features of painted aluminum trim coil include:

Corrosion resistance:

Aluminum itself has excellent corrosion resistance; spray coating further enhances its weather resistance, making it suitable for various climatic conditions.

Lightweight:

Aluminum has a low density and is lightweight, facilitating transportation and installation.

High flexibility:

Aluminum is easy to process; it can be cut, shaped, and bent as needed to adapt to different architectural designs.

Aesthetics:

Coated aluminum trim coils are available in a variety of colors and surface treatments to match architectural styles and enhance overall aesthetics.

Low maintenance:

Painted aluminum typically requires only periodic cleaning and does not require frequent maintenance.

The core purpose of painted aluminum trim coil is for the decoration of building facades and the sealing and protection of edges and joints, especially focusing on "detail finishing" scenarios.
