ALUMINUM PANEL MATERIAL AND CONSTRUCTION

Aluminum panels are made of premium high-strength aluminum alloy sheets, commonly in thicknesses of 2.0, 2.5, and 3.0 mm, using alloy grade 3003 in temper H24, with standard maximum sheet size being 1,300 mm× 4,000 mm. An aluminum panel mainly consists of a face panel, stiffeners, and angle brackets. The angle brackets can either be formed directly by bending and stamping the panel edges or installed separately onto the panel folds. The stiffeners are fastened to the back of the panel using welded studs, creating a solid integrated unit that significantly enhances the panel's strength and rigidity, ensuring long-term flatness and seismic resistance. For sound and thermal insulation, high-efficiency insulating materials can be mounted on the inner side of the aluminum panel.

• Fully recyclable aluminum alloy materials for eco-friendly purposes.

ALUMINUMPANEL PROPERTIES

Properties of other aluminum alloy panels

APPLICATION

Our aluminum curtain wall panels can be customized to meet diverse customer needs. With superior performance and versatile designs, they have become one of the mainstream choices for architectural curtain walls. They are mainly applied in interior and exterior wall decorations in subway stations, high-speed railwaystations, airports, hotels, hospitals, schools, office buildings, shopping malls, sports venues, etc., serving as a keymaterial that balances aesthetics and functionality in urban architecture.

ALUMINUM PANEL SURFACE TREATMENT

The surface of the aluminum panels is coated with a fluorocarbon polymer paint, a type of exterior metal coating mainly containing at least 70% of Kynar 500 or Hylar 5000 fluorocarbon resin and having the most stable molecular structure and excellent durability. PVDF coating enables products to resist longterm exposure to UV rays, industrial emissions, acid rain, and chemical corrosion and maintain color stability and surface gloss over time, and itself maintains its integrity without peeling, cracking, or chalking, fully complying with the American AAMA 2605 quality standard. To ensure world-class product quality, the Company uses advanced imported spraying equipment and applies Kynar-500 PVDF fluorocarbon polymer paint produced by PPG in the United States

QUALITY CONTROL AND TESTING

We strictly observe the ISO9001 quality management system, require rigorous quality testing for each production process, and monitor product quality in real time. We are the first in the industry to establish a product testing laboratory and equip the laboratory with professional staff, with all coating properties tested and inspected in accordance with the American Architectural Manufacturers Association (AAMA) 2605-05 standard.Our products' coating performance meets or exceeds all technical requirements specified in the AAMA 2605-05 standard.

WATER-BASED CERAMIC COATING

Water-based ceramic coating is formulated from purely inorganic compounds and a water-soluble carrier, using nano inorganic resin as the primary base. It incorporates high-hardness, wear-resistant nano metal oxides, silica, and highly weather-resistant inorganic pigments, and is processed through specialized techniques. When applied to molybdenum-based substrates, an inorganic ceramic coating that is a high-performance surface layer is formed, with excellent properties such as high hardness, superior wear resistance, strong chemical resistance to acids, alkalis, salts, and solvents, long-lasting color retention, resistance to chalking aging and extreme weather, high atmospheric pollution resistance, self-cleaning ability, high-temperature resistance, non-combustibility, and Class A1 fire rating. As a next-generation eco-friendly coating, it meets EU SGS environmental standards and passes FDA food contact tests, ensuring that it is non-toxic, harmless to humans and the environment, and highly safe.

Water-based ceramic coating comes with a wide range of colors, including white, neutral, vibrant, gold, and silver, offering extensive design options. It is widely used in aerospace, metro systems, high-speed rail and light rail sectors, as well as the interior and exterior architectural decoration and curtain walls of office buildings, shopping malls, hotels, hospitals, stations, stadiums, exhibition halls, airports, etc.

FLAT ALUMINUM PANELS WITH GAPS

The aluminum panel is installed by securing screws into the gap between two stiffeners, then sealing with sealant. This is the most common installation method. A visible line forms between adjacent panels, adding a dynamic touch to the flat surface. The use of sealants in different colors allows the lines to either blend with or contrast against the panel finish, creating a visual effect tailored to the desired atmosphere.

Wall-Mounted Aluminum Panel Installation Drawing Strip Inlay (Exposed) Installation

FLAT ALUMINUM PANELS WITHOUT GAPS

Tightly joint aluminum panels are installed with minimal spacing in between, creating a flat and seamless visual effect. The refined and integrated design highlights the natural texture of aluminum, with its lustrous sheen conveying lasting gloss and purity, not only enhancing the architectural quality of buildings but also bringing a refined, dynamic visual experience to the surrounding environment.

WALL-MOUNTED INTERLOCKING ALUMINUM PANEL INSTALLATION INSTRUCTIONS:

1. Mark the lines of keels and the finished surfaces of aluminum panels according to design drawings;

2. Determine the working direction and install the main and cross keels (steel square keels) according to the required grid size; ensure that the keel surface is level and plumb;

3. Install the aluminum panels: Follow the installation sequence shown in the drawing (from left to right and from bottom to top); insert the left bracket of each panel into the corresponding slot between the left folded edge of the panel and the keel; secure the right and top brackets with countersunk selftapping self-drilling screws (panel spacing can be adjusted for a seamless and natural fit in indoor scenarios).

INSTALLATION ON CIRCULAR COLUMN WITH GAPS

The installation on circular column with gaps creates a focal point that enhances the sense of three-dimensionality in public spaces. In architectural aesthetics, the emergence of design materials and forms is not merely a chance encounter, but rather a dialogue between inspiration and reality. This creative approach is not only impactful in the present context, but also carries the potential for continuous extension and application.

ANODIZED

ALUMINIUM PANELS

FEATURES

• Made of novel and distinctive materials, offering modern metallic appearance

• Low specific density, weighing only one-third of stainless steel, and easy to fabricate

• Scratch-resistant, with surface hardness comparable to sapphire

• Excellent thermal conductivity, ideal for precision electronic products, solar panels, etc.

• Significantly save surface treatment efforts, improve yield rates, and effectively lower costs

• Permanent, peel-resistant surface oxide layer

In the natural environment, aluminum naturally forms a thin oxide film that provides a certain degree of protection.. However, this untreated aluminum surface is highly susceptible to physical damage and chemical corrosion. Aluminum anodizing is an electrolytic oxidation process in which the surface of aluminum or aluminum alloy is converted into an oxide layer to offer protective, decorative and additional functional properties. On this basis, aluminum anodizing refers specifically to the part of the process that produces the anodic oxide film.

WOOD-GRAIN ALUMINUM PANELS

FEATURES

• Exquisite appearance: wood-grain patterns with realistic effects and well-defined textures

• Fire resistance and durability: Corrosion-resistant, moisture-resistant, and comparable in hardness and strength to solid wood

• Protection against damage: Rust-proof, impact-resistant, and UV-resistant

• Long service life: Maintain color and shape for 10 to15 years

• High versatility: Can be fabricated into a variety of complex shapes; the back can be filled with insulation, soundproofing, or acoustic materials to enhance functionality

• Eco-friendly: Eco-friendly and reduce material waste

Wood-grain aluminum panels are made from internationally advanced decorative materials, offering luxurious and elegant patterns, authentic textures and vibrant colors. The finish is durable and wear-resistant, and the panels are free of formaldehyde and other harmful substances. Non-toxic and environmentally friendly, they eliminate concerns about odors or health risks associated with paints and adhesives used in traditional decoration. With excellent quality, wood-grain aluminum panels are the preferred choice for high-end architectural finishes.
