Aluminum Composite Panel
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 become a global sensation, widely recognized as a luxurious material for building exteriors. Especially when paired with glass facades, they showcase a distinctive charm, thereby providing architects with ample creative space. Aluminum composite panels are a highly popular and premium decorative material for exterior walls in recent years. The base material is high-strength aluminum alloy plates, commonly available in thicknesses of 1.5, 2.0, 2.5, and 3.0mm, with models including 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, thereby preventing discoloration and peeling.
No light pollution
Due to the matte surface of the fluorocarbon coating (with a gloss level 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 its surface, thus providing self-cleaning properties.
Colorful
Fluorocarbon coatings are available in over 100 colors, and can also be custom-mixed to meet specific customer color requirements.
Color variation
Color variation of aluminum composite panels is generally △E=2NBS. To better address color variation issues, our company has specially imported the world-class spraying expert - the Lansi 260-meter full production line, which allows the three-coating process to be completed in one go on the assembly line, ensuring ultra-flatness and no color variation for our products.
Flatness
If the aluminum panel is larger in area, there may be issues with flatness. To better address this, our company guarantees to add one reinforcing rib for every additional square meter (i.e., one reinforcing rib every 500-800mm).
High-tensile
Aluminum composite panels are made from corrosion-resistant aluminum-magnesium alloy sheets, offering high strength. The steel grade of the aluminum panels is significantly enhanced due to the welding technique used at the openings, ensuring the facade's wind resistance, seismic resistance, leakage prevention, and impact resistance.
Flame retardant
Aluminum composite panels for curtain walls, being made of full aluminum panels and PVDF coatings, are fundamentally non-flammable, 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 molding properties
Aluminum composite panels, due to the process of pre-processing and then painting, are versatile for bending, folding, punching, rolling, and welding, allowing the product to be shaped into various geometric forms. This meets the special requirements of architecture and design, fully embodying the designer's concept, which is difficult for other materials to achieve in curtain walls.
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 are easier and faster 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 cost is higher.

Installation Technical Requirements for Aluminum Composite Panels
After the aluminum panel and sub-frame combination 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. Elastic, low-tension lines should be used when pulling the lines to ensure the joints are neat. A layer of heat-activated adhesive should be applied at the contact points between the sub-frame and the main frame, and rigid joints are not permitted. After the panel positioning, insert the two legs of the spacer into the depression under the sub-frame, and tighten the clips on the spacer. The gap between aluminum panels is generally 10-20u, sealed with silicone or rubber strips, etc. Place a pad bar inside the overlapping joints.
