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 exterior materials. Particularly, when paired with glass facades, aluminum curtain walls stand out even more, thus providing architects with ample design space. Aluminum composite panels have become a highly popular and premium decorative material for exterior walls in recent years. The base material of aluminum composite panels is 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 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 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 properties
Due to the unique molecular structure of KYNAR500 in the fluorocarbon coating, dust cannot adhere to the surface, thus providing self-cleaning properties.
Rich in colors
Available in over 100 fluorocarbon paint colors, we can also create custom hues to cater to specific customer needs, fully satisfying their unique color requirements.
Color variation
The color difference of aluminum panels is generally △E=2NBS. To better address the issue of color difference, our company has specially imported the world-renowned spraying expert, the Lancing 260-meter full production line, which enables the three-coating process to be completed in one operation on the assembly line, ensuring ultra-flatness and no color difference in the products.
Flatness
If the aluminum panel has a large individual 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, offering high strength. The welding technique at the openings significantly enhances the rigidity of the aluminum panels, ensuring the facade's wind resistance, seismic resistance, waterproofing, and shockproof performance.
Flame retardant properties
Aluminum composite panels for curtain walls, being made of solid aluminum sheets and PVDF coatings, are fundamentally non-combustible, offering an unparalleled advantage over aluminum-plastic panels.
Lightweight
The weight of aluminum 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, due to the process of pre-processing and then painting, can be bent, folded, punched, rolled, and welded into various geometric shapes. This allows for meeting the special requirements of architecture and design, fully reflecting the designer's concept, which is difficult for other materials in curtain walls to achieve.
High material utilization rate
Aluminum-plastic panels and stone curtain walls have higher processing costs due to limited specifications, whereas aluminum single sheets 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 offer ease and speed in installation, construction, and replacement. 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 cost is higher.
Aluminum composite panels are typically installed on exterior walls using the following methods:

Installation Technical Requirements for Aluminum Composite Panels
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 the design. Before installing the panels, a two-machine alignment line should be pulled out on the frame to determine the joint release position. Use a line with low elasticity when pulling the line to ensure the joints are neat. A layer of thermal sealant should be added at the contact points between the subframe and the mainframe, and rigid joints are not allowed. After the positioning of the panels, insert the two feet of the down panel into the concave of the subframe under the panel, and then tighten the bolts 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.
