Hammer embossed aluminum coil, also known as pebble embossed aluminum coil, is an aluminum sheet or coil material with a hammered or dimpled surface pattern created by mechanical rolling or embossing techniques. This pattern is produced through the embossing process, which adds texture to the material. Due to its aesthetics and functional advantages (such as enhanced grip and reduced glare), this aluminum coil is widely used in architecture, automotive, and decorative fields.
Hammer embossed aluminum sheet coil combines aesthetics, durability, and functionality, making it the preferred choice across various industries.

Hammer Embossed Aluminum Sheet Alloys
Hammer embossed aluminum sheets and coils are available in a variety of aluminum alloys, each with unique properties suited for different applications. The most commonly used alloys for embossed aluminum products include the 1000 series (particularly 1050, 1060, and 1100), 3003 alloy, and 5052 alloy. Each alloy provides a different balance of formability, strength, and corrosion resistance.
3003 aluminum alloy is one of the most popular choices for embossed aluminum applications. Essentially a commercially pure aluminum with about 1.2% manganese added, it offers about 20% higher strength than 1100-grade aluminum while maintaining excellent corrosion resistance. This alloy has good workability and can be effectively deep drawn, spun, welded, or brazed. It is non-heat-treatable and is usually supplied in tempers such as H114, H134, etc., with thicknesses ranging from 0.025 inch (0.635 mm) to 0.080 inch (2.032 mm) or greater.
Hammer Embossed Aluminum Sheet Surface Treatments
Surface treatment methods for hammer embossed aluminum significantly extend its functionality and aesthetics.
Anodized Hammer Embossed Aluminum Sheet
Anodizing forms a dense alumina film on the surface, enhancing corrosion resistance, and allows color impregnation while retaining the hammered texture.
Color Coated Hammer Embossed Aluminum Sheet
Color coating options include Polyester (PE), High Durability Polyester (HDP), and Fluorocarbon (PVDF) coatings, with service lives ranging from 7-8 years for standard polyester coatings to 20-25 years for PVDF coatings.
Polished Mirror Hammer Embossed Aluminum Sheet
Polished mirror finishing provides high reflectivity (over 82%) while retaining the hammered texture, making it suitable for decorative lighting applications.
Surface quality of Hammer Embossed Aluminum Sheet Coil
- Horizontal difference: The horizontal thickness difference between the embossed oxide plate and the pattern is within 0.02mm.
- Pattern height: The hammer pattern height is between 0.11mm and 0.15mm, and special height can be customized.
- Anodizing thickness: 5μm to 10μm.
- Mechanical properties: Meet conventional application requirements and international standards.
- Surface: No cracks, corrosion, oil spots, tiger stripes, etc.
Features of Hammer Embossed Aluminum Sheet
- Reflectivity: The hammered pattern diffuses light, ideal for applications requiring low glare or uniform illumination.
- Corrosion Resistance: Anodized surface (5-10 μm oxide layer) resists moisture and chemicals, suitable for marine or humid environments.
- Formability: Easy to cut, bend, or weld, can be custom manufactured to client requirements. Common tempers include H14, H24, and O (annealed) to provide different flexibility.

Production Process of Hammer Embossed Aluminum Coil
First, the aluminum coil undergoes thorough cleaning and degreasing to remove any contaminants that may affect embossing quality.
Then, the material is preheated to a specific temperature to improve ductility, after which it passes through special embossing rollers or presses, using a combination of pressure and heat to impart the hammered pattern.
After embossing, the material is rapidly cooled to fix the pattern and stabilize its mechanical properties.
Before cutting the material into required specifications, optional surface treatments such as anodizing, painting, or coating can be applied to enhance corrosion resistance or aesthetics.
