Aluminum Sheet
Aluminum composite panels are used for the decorative facades of buildings, originating in Europe and America in the 1950s. 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. Especially when paired with glass facades, aluminum curtain walls stand out even more, providing architects with ample design space. Aluminum composite panels are a highly popular and advanced decorative material used for exterior walls in recent years. The base material of aluminum composite panels is made from 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, and 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, thus 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 its surface, thus providing self-cleaning properties.
Rich colors
Fluorocarbon coatings come in over 100 colors and can be customized to create special hues to fully meet the unique color requirements of our clients.
Color variation
The color difference of aluminum panels is generally △E=2NBS. To better address color difference issues, our company has specially imported the world-class spraying expert - the Lancer 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 area of a single aluminum plate is large, it may have flatness issues. To better address this, our company guarantees to add a reinforcing rib every 1 square meter (i.e., every 500-800mm) for reinforcement.
High-tensile
Aluminum composite panels are made from corrosion-resistant aluminum-magnesium alloy sheets, offering high strength. The welding technique used at the openings significantly enhances the rigidity of the aluminum panels, ensuring excellent wind resistance, seismic resistance, leak-proofing, and impact resistance for the facade.
Flame retardant
Aluminum composite panels for curtain walls, made entirely of aluminum panels and PVDF coatings, are fundamentally non-combustible, offering an unparalleled 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 shaping properties
Aluminum composite panels, due to their pre-processing and painting technique, are highly versatile for bending, folding, punching, rolling, and welding, enabling the creation of various geometric shapes. This versatility caters to the unique requirements of architecture and design, fully reflecting the designer's concept, a capability that other materials for curtain walls struggle 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 customized according to customer drawings without incurring additional processing expenses.
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 panels, and the installation cost is higher.

Installation Technical Requirements for Aluminum Composite Panels
After the aluminum panel and subframe are assembled, 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 less elastic line when pulling the lines to ensure the joints are neat. A layer of thermal adhesive 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 legs of the down panel into the depression of the subframe, and tighten the bolts on the pressure plate. The gap between aluminum panels is generally 10-20u, sealed with silicone or rubber strips, etc. Place a pad bar inside the overlapping joints.
