Aluminum Composite Panel
Aluminum composite panels are used for the decoration of both interior and exterior walls 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 worldwide popularity and are widely recognized as luxurious building facades. When paired with glass facades, aluminum cladding stands out even more, providing architects with extensive design possibilities. Aluminum composite panels have become a highly popular and advanced 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 models including 1100, 1060, 3033, and temper H24. Their structure is primarily composed 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 fluoro-carbon coated surface (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.
Colorful
Available in over 100 colors of fluorocarbon coatings, we can also create custom hues to meet specific customer color requirements.
Color variation
Aluminum panel color variation is generally △E=2NBS. To better address color variation issues, our company has specially imported the world-class Lancer 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 color consistency 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 a reinforcing rib every 1 square meter (i.e., one rib every 500-800mm).
High-strength
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 the facade's wind resistance, seismic resistance, leakage prevention, and shock resistance.
Flame retardant
Aluminum composite panels, being made of solid aluminum and PVDF coatings, are inherently non-flammable, offering an unmatched advantage over plastic-aluminum composite 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 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 embodying 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 panels can be custom-made according to customer drawings without incurring additional processing expenses.
Easy installation and construction
Aluminum itself has a low density, and since the aluminum composite panels for curtain walls are pre-formed before installation, they are easy and quick to install, construct, and replace. Although significant improvements have been made to 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 sub-frame 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, and the positions of the panel joints should be fixed. Use a low elasticity line when pulling the line to ensure the joints are neat. A layer of thermal adhesive should be added at the contact points between the sub-frame and the main frame, and rigid joints are not permitted. After the position of the panel is fixed, insert the two feet of the bracket into the depression of the sub-frame under the panel, and tighten the nuts on the bracket. The gap between aluminum panels is generally 10-20u, and can be sealed with silicone or rubber strips, etc. Place a pad bar inside the overlapping joints.
