Aluminum Composite Panel
Aluminum composite panels are used for the decorative facades of buildings both internally and externally, originating in the 1950s in Europe and America. Their unparalleled advantages in terms of aesthetics, weather resistance, and safety have made them extremely popular worldwide, becoming the recognized material for luxurious building exteriors. Particularly, when paired with glass facades, aluminum cladding showcases a distinct charm, thus offering architects a vast creative space. Aluminum composite panels have become a highly favored and premium decorative material for building exteriors 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 models including 1100, 1060, 3033, and temper H24. Their construction 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
The unique molecular structure of KYNAR500 in the fluorocarbon coating prevents dust from adhering to its surface, thereby providing self-cleaning properties.
Colorful
Fluorocarbon coatings are available in over 100 colors, and we can also create special 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 color variation issues, our company has specifically introduced the world-class Lanz 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 for the 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 a reinforcing rib every 1 square meter (i.e., every 500-800mm).
High-tensile
Aluminum composite panels are made from corrosion-resistant aluminum-magnesium alloy sheets, offering high strength. Additionally, the use of welding techniques at the openings significantly enhances the rigidity of the aluminum panels, ensuring the facade's wind resistance, seismic resistance, leakage prevention, and impact resistance.
Flame retardant
Aluminum composite panels for curtain walls, being made entirely of aluminum panels and PVDF coatings, are inherently non-combustible, offering an unparalleled advantage over aluminum-plastic panels.
Lightweight
The weight of aluminum composite 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, processed with a pre-coating technique, are versatile for bending, folding, punching, rolling, and welding, allowing the creation of various geometric shapes. This versatility meets the unique requirements of architecture and design, fully reflecting the designer's vision—a capability that is difficult to achieve with other materials for curtain walls.
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 expenses.
Easy installation and construction
Aluminum itself has a low density, and since the aluminum panel curtain wall is pre-formed before installation, it is relatively easy and quick to install, construct, and replace. Although other materials' curtain walls have made significant improvements in installation, they still do not match the convenience of aluminum panel curtain walls, and the installation cost is 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 sub-frame 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 casing to determine the joint release positions. Use a line with low elasticity when pulling the lines to ensure the joints are neat. A layer of heat-sealant should be added at the contact points between the sub-frame and the main frame to prevent rigid joints. After the panels are positioned, insert the two legs of the drop piece into the indentation under the sub-frame on 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.
