What Is Decorative Aluminum Sheet
Dec 30 25
The decorative aluminum sheet is made from pure aluminum or aluminum alloys as the base material, processed through rolling, shearing, and surface treatment (such as anodizing, spraying, and coating). It is mainly used in architectural decoration, interior decoration, and home beautification.
Common alloys
1. 1000 series (pure aluminum series)
1050 and 1060 alloys are often chosen. Their advantages include good plasticity, ease of processing and forming, excellent gloss after surface treatment, and relatively affordable price. The disadvantage is lower strength, making them unsuitable for load-bearing or high-strength applications. Suitable for interior ceilings, wall decorations, and home furnishings where high strength is not required.
2. 3000 series (aluminum-manganese alloy series)
The core alloy component is manganese, represented by aluminum 3003 and 3004. Compared to the pure aluminum series, they have higher strength, good corrosion resistance and weldability, and excellent plasticity, allowing them to adapt to complex processing techniques (such as bending and stamping).
Combining cost-effectiveness and practicality, it can be widely used in interior and exterior decoration, such as wall panels, door and window frames, and advertising signs, especially suitable for humid environments (such as bathrooms and kitchens).
3. 5000 series (aluminum-magnesium alloy series)
With magnesium as the main alloying element, representative models are 5052 and 5083. It belongs to medium-to-high strength aluminum sheets, with strength far exceeding that of the 1000 and 3000 series, and excellent corrosion resistance (especially against seawater corrosion), while also possessing good toughness and fatigue resistance.
The price is relatively high, suitable for decorative scenarios requiring high strength and durability, such as outdoor curtain walls, high-end doors and windows, and elevator car decoration, capable of long-term resistance to outdoor wind, rain, and ultraviolet radiation.
Specifications
1. Thickness
The thickness ranges widely, from 0.3mm to 10.0mm, with different thicknesses suitable for different applications:
- Thin (0.3-1.0mm): Primarily used for ceilings, partitions, and home decoration panels; lightweight and easy to cut and install.
- Medium-thick (1.0-3.0mm): Suitable for wall decoration, door and window frames, and advertising signs; moderate strength, balancing aesthetics and practicality.
- Thick (3.0-10.0mm): Often used for outdoor curtain walls, elevator decoration, and large decorative structures; requires withstanding certain pressure and external forces, offering higher safety.
2. Dimensions
The standard size is 1220mm × 2440mm (consistent with ordinary board dimensions, suitable for standard decoration needs). Custom sizes are also supported, such as 1000mm × 2000mm and 1500mm × 3000mm, which can be cut to the actual dimensions of the decoration design to reduce material waste. For large-scale decorative projects (such as curtain walls and large wall surfaces), larger aluminum panels can be customized to enhance the overall decorative integrity.
3. Surface Condition
The surface condition directly affects the decorative effect. Common types include:
- Natural: Without special surface treatment, showcasing the metallic luster of the aluminum panel itself, simple and elegant, suitable for industrial and minimalist styles;
- Anodizing: Anodizing forms an oxide film on the surface, resulting in higher hardness and corrosion resistance. Available in various colors such as natural, gold, and silver, with a delicate texture;
- Spray coating: Including powder coating and fluorocarbon coating, offering rich colors, strong adhesion, and good weather resistance. Fluorocarbon coating is particularly suitable for outdoor applications, resisting UV rays and weathering;
- Coating: Covering the surface with a PVC film or wood grain film simulates wood grain, stone grain, and other textures, offering strong decorative appeal and easy cleaning, suitable for home decoration and commercial spaces.
Multi-purpose uses
1. Interior decoration
The decorative aluminium sheet can be used for ceilings, wall decoration, partitions, elevator car decoration, feature walls, etc. For example, anodized aluminum panels are lightweight, aesthetically pleasing, and easy to clean for ceilings; wood-grain coated aluminum panels simulate real wood textures, are environmentally friendly, and durable; and colored aluminum panels are used as partitions, both dividing space and enhancing its decorative appeal.
2. Outdoor decoration
Suitable for building curtain walls, door and window frames, awnings, advertising signs, and landmark building decorations. Outdoor applications require materials with high weather resistance; fluorocarbon coated or aluminum-magnesium alloy panels are preferred, as they can withstand wind, rain, and UV radiation for extended periods, maintaining their integrity and aesthetic appeal.
3. Home and commercial decoration
Suitable for home furnishings (such as coffee table tops, wardrobe doors, and cabinet doors) and commercial spaces (such as shop entrances, showroom decorations, and department store counters). For example, metallic aluminum panels are eye-catching and textured for shop entrances; custom-colored aluminum panels for showroom decorations highlight the features of exhibits and enhance the overall style of the showroom.
4. Special scene decoration
Due to its corrosion resistance and environmental friendliness, it can also be used in scenes with high environmental requirements such as hospitals, laboratories, and food processing plants. It can meet both decorative needs and hygiene standards, and is easy to clean and does not easily breed bacteria.
