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 gained global popularity and are widely recognized as luxurious building materials for exterior walls. Particularly, when paired with glass facades, aluminum curtain walls stand out even more, thus providing architects with ample creative space. Aluminum composite panels are a highly popular and sophisticated decorative material for exterior walls 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 types including 1100, 1060, and 3033, and temper H24. Their structure mainly 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 color change and peeling.
No light pollution
Due to the matte finish of the fluorocarbon coating (with a gloss level of around 35), it scatters light rather than reflecting it, thus preventing light pollution. This 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 its surface, thus providing self-cleaning properties.
Rich in colors
Fluorocarbon coatings come in over 100 colors and can be customized to create special hues to fully cater to customers' unique color needs.
Color variation
The color difference of aluminum panels is generally △E=2NBS. To better address color variation issues, our company has specifically introduced the world-renowned Langs 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 no color variation in our products.
Flatness
If the aluminum plate is larger in area, 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 rib every 500-800mm).
High-tensile
Aluminum composite panels are made from corrosion-resistant aluminum-magnesium alloy sheets, featuring high strength. Due to the welding process at the cut edges, the rigidity of the aluminum panel is significantly enhanced, ensuring the facade's wind resistance, shock resistance, leak prevention, and impact resistance.
Flame Retardancy
Aluminum composite panel facades, made entirely of aluminum sheets and PVDF coatings, are fundamentally non-combustible, offering an unmatched advantage over aluminum-plastic panels.
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 molding properties
Aluminum composite panels, due to their pre-processing and painting technique, can be bent, folded, punched, rolled, and welded into various geometric shapes, thus meeting the special requirements of architecture and design. This capability is something that other materials for curtain walls struggle to achieve, fully embodying the designer's vision.
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 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 there have been significant improvements in the installation of curtain walls made from other materials, they still do not match the convenience of aluminum composite panel curtain walls, and the installation costs are higher.
Aluminum composite panels are typically installed on exterior walls using the following methods:

Technical Requirements for Aluminum Composite Panel Installation
After the aluminum panel and subframe are assembled, installation begins on the main frame. The density of the panel joints is determined by design. Before installing the panels, a two-machine communication line should be pulled out on the casing to determine the position of the joint release. Use a less elastic line when pulling the line to ensure the joints are even. A layer of adhesive heat should be added at the contact point between the subframe and the mainframe, and rigid joints are not allowed. After the positioning of the panels, insert the two legs of the down panel into the recess of the subframe, and tighten the clamps on the pressure plate. The gap between the aluminum panels is generally 10-20u, sealed with silicone or rubber strips, etc. Place a pad bar inside the overlapping joints.
