1. Constitution:
The aluminum honeycomb panel consists of three main layers:
Panel: Made from high-quality aluminum alloy sheets (commonly 3003,5052 alloys), the surface can be treated with fluorocarbon spraying, polyester spraying, anodizing, wood grain transfer printing or film coating, offering a wide range of colors, textures and weather-resistant protection.
Underplate: Similarly constructed from aluminum alloy, the thickness can be flexibly adjusted according to indoor/outdoor environmental conditions and mechanical requirements, and may also be coated with appropriate anti-corrosion finishes.
Honeycomb core layer: A regular hexagonal honeycomb structure is formed by bonding multiple layers of aluminum foil with joint adhesive and stretching them apart. The core materials are densely arranged, exhibiting both gas and sound wave transmission capabilities without obstruction. The thickness of the aluminum foil core layer and its side length dimensions (commonly 6mm, 8mm, 10mm, etc.) determine the panel's compressive and shear strength as well as its density.
This I-beam mechanical configuration—comprising a panel, core layer and base plate—enables the ultra-thin panel to achieve exceptional specific strength and stiffness despite its minimal self-weight.
2.1. Extremely lightweight, yet maintaining its strength
The standard 15mm-thick aluminum honeycomb panel (e.g., 1.0mm face plate + 0.5mm base plate) weighs only 5–6 kg per square meter, whereas aluminum single panels with equivalent stiffness typically weigh over 20 kg. Its weight is merely one-fifth that of traditional aluminum single panels and one-twentieth that of stone, significantly reducing the structural load on buildings and the required support framework. This makes it particularly suitable for super-high-rise buildings and lightweight design applications.
2.2. Superior flatness, reduced optical distortion
The honeycomb core divides the panel into countless microscopic load-bearing units, completely eliminating the "tank effect" and wave deformation caused by temperature and gravity in metal sheets. The surface flatness tolerance is controlled within 1 mm, with no visible waves under sunlight, resulting in a pristine and smooth curtain wall facade with an exceptionally sophisticated appearance.
2.3. Heat insulation, energy-efficient and low-noise
The honeycomb core traps air within numerous independent micro-cavities, effectively inhibiting thermal convection and acoustic transmission. When combined with an appropriately thick air layer or backing material, the heat transfer coefficient of the panel can be significantly reduced, achieving an airborne sound insulation reduction of over 25–30 dB. This substantially enhances indoor comfort and reduces building operational energy consumption.
2.4. Class A fire resistance – safe and reliable
The honeycomb panel, composed of aluminum alloy and inorganic adhesive, is a non-combustible material with a fire resistance rating of Class A. It does not produce toxic smoke during combustion, nor does it spread flames, meeting the stringent fire safety requirements for both indoor and outdoor building decorations.
2.5. Weather-resistant and corrosion-resistant, with an exceptionally long service life
The surface coating, combined with a scientifically designed pretreatment process for the metal substrate, withstands over 4,000 hours of salt spray testing and ultraviolet aging tests, demonstrating excellent corrosion resistance, color retention and low contamination susceptibility. Under normal use and maintenance conditions, its service life exceeds 30 years.
2.6. Green and environmentally friendly
Aluminum alloy itself possesses significant recyclability value, as it does not emit harmful volatile gases during production. It meets the requirements for the proportion of recycled materials in LEED and China's green building certification standards, and is easy to dismantle and recycle, making it a typical sustainable building material.
Aluminum honeycomb panels offer extensive customization options, with maximum panel dimensions reaching 1500mm × 6000mm or even longer. They can be manufactured in conventional thicknesses ranging from 6mm to 50mm, with 15mm–25mm commonly used for building curtain walls, 10mm–20mm for interior partitions, and thicker thicknesses available for traffic floors and load-bearing components as needed. The core cell side dimensions are available in 6mm, 8mm, and 10mm; smaller cells result in more surface adhesive joints, enhancing panel flatness and bonding strength, while the aluminum foil core thickness can be adjusted to meet shear resistance requirements.
Building exterior walls and curtain walls: Designed for high-rise facades, canopy eaves, airports, stations and other large public structures, they replace aluminum panels to maintain straight lines and mirror-like flatness over the long term while reducing steel consumption in the main structure.
Interior decoration: Widely applied in lobbies, elevator cabins, column enclosures, ceilings, partitions, and integrated wall-mounted systems. The panels can be manufactured with extremely thin thicknesses to achieve seamless visual coverage over large areas without warping, supporting a concealed installation system and facilitating rapid dry-construction processes.
Transportation Manufacturing: Subway and high-speed rail carriage floors and wall panels, aircraft cargo cabin panels, yacht interior cabins, and passenger ship partitions fully leverage their advantages in lightweight design, vibration resistance, and sound insulation, thereby reducing energy consumption and enhancing transport capacity.
Industrial Equipment and Home Appliances: High-end equipment racks, cleanroom wall panels, printing platforms, and textile machinery pallets, offering high planarity, dust-free surfaces and damping vibration characteristics.
Furniture and Display: Designed for creating ultra-lightweight large-span tabletops, exhibition panel panels, and movable partitions, featuring a minimalist yet sophisticated aesthetic.
Aluminum alloy honeycomb panels can be precisely formed through streamlined processes including CNC cutting, edge grinding, bending (with pre-cut grooves), thread tapping and pre-embedded fasteners. Installation typically employs angle codes, back bolts, or fastening strip systems, making them ideal for modular dry-hanging and rapid interior installation. The panels themselves offer continuous high strength, enabling increased stud spans and reduced stud quantities in curtain wall designs. The finished products require no additional on-site processing, enabling an efficient workflow from factory customization to green on-site installation.
