Painted Aluminum Sheet RAL7016 Anthracite Gray

RAL 7016, commonly known as anthracite gray, is a dark grey with a modern and elegant look. Aluminum ral 7016 is widely used in architectural and industrial design, especially in aluminum sheet coating, and is favored for its durability and aesthetics. Painted aluminum sheet ral 7016 not only retains the advantages of aluminum itself such as light weight and corrosion resistance, but also adds decorativeness, durability and specific functionality (such as UV resistance, self-cleaning function, etc.) through surface coating. RAL 7016 anthracite painted aluminum sheet is particularly suitable for design projects that pursue low-key luxury and modern minimalist style.

RAL 7016 anthracite grey painted aluminum sheet is achieved by coating multiple layers of functional coatings on the surface of aluminum substrate. Its core technical parameters include:

- Substrate selection:

Common aluminum grades: 3003, 3004, 5052, etc., with a thickness range of 0.3-2.0mm.

Surface treatment: Use chromization or chromium-free passivation process to enhance coating adhesion.

- Coating structure:

Primer: epoxy resin or polyester resin, thickness 5-8μm, providing anti-corrosion and adhesion properties.

Topcoat: Polyester (PE) or fluorocarbon (PVDF) coating of RAL 7016 color, thickness 15-25μm, determines color and weather resistance.

Backcoat: Optional transparent or white coating, thickness 5-10μm, protect aluminum and balance stress.

- Performance indicators:

Weather resistance: PVDF coating can reach 15-20 years, PE coating is about 8-10 years (according to ASTM G154 standard).

Corrosion resistance: pass neutral salt spray test (NSS) ≥1000 hours (PVDF coating).

Hardness: pencil hardness ≥2H (ASTM D3363 standard).

Flexibility: T bend test ≤2T (no cracks).

Features of painted aluminum sheet ral 7016:

- Beautiful: RAL 7016 has a deep and stable color, suitable for modern architectural style, and can be matched with a variety of colors and materials.

- Weather resistance: Painted aluminum sheets generally have good weather resistance, can resist the influence of ultraviolet rays, rain and other environmental factors, and maintain color stability.

- Corrosion resistance: Aluminum itself has good corrosion resistance, and the coating further enhances this property, making it suitable for outdoor environments.

- Easy to clean: The smooth coating surface makes cleaning and maintenance easier.

- Environmental protection: Aluminum materials are recyclable, and many coatings meet environmental standards, reducing the impact on the environment.

Application areas of painted aluminum sheet ral 7016:

- Smoked gray color-coated aluminum sheets are widely used in the following fields:

- Building facades: used for exterior wall decoration of modern buildings.

- Window frames and doors: As materials for window frames and doors, it provides modernity and durability.

- Interior decoration: used for interior walls, ceilings and other decorative elements.

- Home appliances: used in the surface coating of home appliances to enhance appearance and durability.
