Aluminum Composite Panel
Aluminum composite panels are used for the decorative facades of buildings, originating in the 1950s in Europe and America. Due to their unparalleled advantages in terms of aesthetics, weather resistance, and safety, they have become a global phenomenon, widely recognized as a luxurious material for building exteriors. Especially when paired with glass facades, they stand out even more, providing architects with extensive creative space. Aluminum composite panels have emerged as a highly popular and sophisticated decorative material for exterior walls in recent years. The base material is made from high-strength aluminum alloy sheets, commonly available in thicknesses of 1.5, 2.0, 2.5, and 3.0mm, with types including 1100, 1060, 3033, and temper H24. Their structure is primarily composed 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 gloss level of around 35), it exhibits diffused reflection and does not cause light pollution, which offers a significant advantage over glass curtain walls.
Self-cleaning
Due to the unique molecular structure of KYNAR500 in the fluorocarbon coating, dust cannot adhere to the surface, thus providing self-cleaning properties.
Rich colors
Fluorocarbon coatings come in over 100 colors and can be custom created to match specific customer needs, fully catering to unique color requirements.
Color variation
The color difference of aluminum composite panels is generally △E=2NBS. To better address color variation issues, our company has specially introduced the world-renowned 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 color consistency in our 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 that an additional reinforcing rib will be added per square meter (i.e., one rib every 500-800mm).
High-tensile
Aluminum composite panels are made from corrosion-resistant aluminum-magnesium alloy sheets, featuring high strength. Moreover, the use of welding techniques at the openings significantly enhances the rigidity of the aluminum panels, ensuring excellent wind resistance, seismic resistance, leakage prevention, and impact resistance for the facade.
Flame retardant
Aluminum composite panels are made of solid aluminum sheets and PVDF coatings, making them fundamentally non-combustible—a significant advantage over aluminum-plastic panels that cannot be matched.
Lightweight
The weight of aluminum composite panel curtain walls is only 1/10 of glass curtain walls and 1/20 of stone curtain walls.
Good shaping properties
Aluminum composite panels, due to their pre-processing and painting technique, are versatile for bending, folding, punching, rolling, and welding, allowing the creation of various geometric shapes. This enables the fulfillment of unique architectural and aesthetic requirements, fully embodying the designer's concept, a feat that is difficult for other materials in curtain wall construction.
High material utilization rate
Aluminum-plastic panels and stone curtain walls have higher processing costs due to limited specifications, whereas aluminum single panels can be customized according to customer drawings without incurring additional processing costs.
Easy installation and construction
Aluminum itself has a low density, and since the aluminum composite panels are pre-formed before installation, they are relatively easy and quick to install, construct, and replace. Although other materials' facades have made significant improvements in installation, they still do not match the convenience of aluminum composite panels, and the installation costs are higher.
Aluminum composite panels are typically installed on exterior walls.

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 joints between panels is determined by design. Before installing the panels, two machine alignment lines should be pulled out on the frame to determine the joint positions. Use a line with low elasticity when pulling the lines to ensure the joints are even. A layer of thermal glue should be added at the contact points between the subframe and the mainframe, and rigid joints are not allowed. After the panel positioning, insert the two legs of the drop piece into the concave part of the subframe below the panel, and tighten the bolts on the clamp piece. The gap between aluminum panels is generally 10-20u, sealed with silicone or rubber strips, etc. Place a spacer bar inside the overlapping joints.
