Aluminum Composite Panel
Aluminum composite panels are used for the decorative facades of buildings both internally and externally, originating in the 1950s in Europe and America. Due to their unparalleled advantages in terms of aesthetics, weather resistance, and safety, they have gained worldwide popularity and are recognized as a luxurious choice for building exteriors. Particularly, when combined with glass facades, aluminum curtain walls stand out even more, thus providing architects with extensive creative space. Aluminum composite panels are a highly popular and advanced decorative material used for building exteriors in recent years: the base material is made of high-strength aluminum alloy sheets, commonly available in thicknesses of 1.5, 2.0, 2.5, and 3.0mm, with grades such as 1100, 1060, 3033, and temper H24. Their structure primarily consists of panels, reinforcing ribs, and corner codes.
Corrosion resistance
High KYNAR 500 resin content in the surface PVDF effectively resists acid rain, air pollution, and UV degradation, thereby preventing discoloration and peeling.
No light pollution
Due to the matte finish of the fluorocarbon coating (with a luster of about 35), it scatters light rather than reflecting it, thus preventing light pollution. This offers a significant advantage over glass curtain walls.
Self-cleaning properties
Due to the unique molecular structure of KYNAR500 in the fluoro-carbon coating, dust cannot adhere to its surface, thus providing self-cleaning properties.
Colorful
Fluorocarbon coatings are available in over 100 colors, and we can also create custom hues to meet the unique color requirements of our customers.
Color variation
The color difference of aluminum panels is generally △E=2NBS. To better address color difference issues, our company has specially引进d the world-class coating expert, the Lancer 260-meter full production line, which allows the three-coating process to be completed in a single operation on the assembly line, ensuring ultra-flatness and zero color difference for the products.
Flatness
If the area of a single aluminum panel is large, there may be issues with flatness. To better address this, our company guarantees to add a reinforcing rib every 1 square meter (i.e., one reinforcing rib every 500-800mm).
High-strength
Aluminum composite panels are made from corrosion-resistant aluminum-magnesium alloy sheets, offering high strength. Additionally, the use of welding techniques at the openings significantly enhances the rigidity of the aluminum panels, ensuring excellent wind resistance, seismic resistance, leak-proofing, and impact resistance for the curtain wall.
Flame Retardant
Aluminum composite panels are non-combustible due to their construction with full aluminum sheets and PVDF coatings, offering an unparalleled advantage over aluminum-plastic panels.
Lightweight
The weight of aluminum single-panel curtain walls is only 1/10 that of glass curtain walls and 1/20 that of stone curtain walls.
Good shaping properties
Aluminum composite panels, processed with a pre-coating and then fabrication technique, are versatile for bending, folding, punching, rolling, and welding, enabling the creation of various geometric shapes. This capability fulfills the special requirements of architecture and design, fully reflecting the designer's vision, which is a feat that other materials' curtain walls struggle to achieve.
High material usage rate
Aluminum-plastic panels and stone curtain walls have higher processing costs due to limited specifications, whereas aluminum single panels can be custom-made according to customer drawings without incurring additional processing costs.
Easy installation and construction
Aluminum itself has a low density, and since aluminum composite panels are pre-formed before installation, they are easy and quick to install, construct, and replace. Although other materials for curtain walls have made significant improvements in installation, they still do not match the convenience of aluminum composite panels, and the installation costs are higher.

Technical Requirements for Aluminum Composite Panel Installation
After the aluminum panel and subframe assembly is completed, installation begins on the main frame. The density of the joint between panels is determined by the design. Before installing the panels, two machine alignment lines should be pulled out on the frame, and the position of the joint release should be marked. Use a line with low elasticity when pulling the line to ensure the joints are neat. A layer of heat-activated glue should be added at the contact points between the subframe and the main frame to prevent rigid joints. After the panels are positioned, insert the two legs of the bracket into the concave area under the subframe on the panel. Tighten the bolts on the bracket to secure it. The gap between aluminum panels is generally 10-20u, sealed with silicone or rubber strips, etc. Place a spacer bar inside the overlapping joints.
