Stone grain aluminum sheets are a type of decorative aluminum product that feature a textured, stone-like finish. With various granite patterns, stone patterns, marble patterns, stone coated aluminum sheets are often used in architectural applications, interior design and manufacturing due to their aesthetic appeal and durability.
Stone grain coated aluminum sheet can simulate the texture of natural stone to achieve a realistic decorative effect. Relatively light weight, easy installation, and reduced difficulty of construction and cost. It has good durability and weather resistance and is not easy to fade or deform. It is often used in building facades and interior decoration as an alternative to expensive natural stone.
What’s more, stone pattern aluminum sheet is lightweight. In the case of the same area, the quality of the aluminum is about 1/10 to 1/12 of the brick wall painting,1/15 of the quality of the dry hanging marble and granite curtain wall, and 1/5 to 1/7 of the concrete hanging plate. Due to the quality of the interior and exterior walls of the building is 1/4 to 1/5 of the total amount of the building, we use aluminum veneer can greatly reduce the quality of the building and the low maintenance cost and high-cost performance. The load of the building structure and foundation is greatly reduced.

Color Options of Stone Grain Coated Aluminum Sheet:
Common Patterns:
Mimics the speckled appearance of granite, often available in various colors such as black, grey and beige. This pattern can give a classic and elegant look.
Features a smooth, veined pattern similar to natural marble. This finish is popular for high-end applications, offering a luxurious appearance.
Resembles the rough texture of slate stone, often in darker tones. This pattern can add a rustic or industrial feel to a space.
Mimics the softer, more subtle patterns of limestone, usually in earthy tones. This finish can provide a warm, natural look.
Designed to replicate the unique textures and colors of travertine stone, often featuring a mix of light and dark shades.
Features a more uniform, dark appearance that resembles natural basalt stone, typically used in contemporary designs.

Process of Coil Coating
Advantages of Marble Grain Aluminum Coil:
The surface features realistic stone patterns and clear textures, creating a variety of stone effects, such as marble and granite. The visual effect resembles natural stone, enhancing the building's class and overall image.
Made of aluminum alloy, it is lightweight, easy to install and transport, while providing sufficient strength and durability to meet the decorative needs of various buildings.
It offers excellent fire resistance and meets building safety standards. It is corrosion-resistant, UV-resistant, and weather-resistant, allowing for long-term use in harsh environments. The surface coating is stain-resistant, easy to clean, and low-maintenance.
It is recyclable and meets green building requirements.
Applications of Stone Coated Aluminum Sheet:
Used in wall panels, ceiling, column cladding, cabinetry, and furniture for a modern look.
Ideal for building exteriors where a stone appearance is desired without the associated weight.
Suitable for exterior decoration of high-rise buildings, commercial complexes, hotels, and more.
Commonly used in public spaces such as subway stations, airports, and high-speed rail stations, enhancing the aesthetics and modern feel of the space.
