Aluminum honeycomb panels are suitable for civil construction, vehicle and ship decoration, etc. The entire processing process is completed in a modern factory, using hot pressing or cold pressing technology. Due to the high thermal conductivity between the aluminum skin and the honeycomb, the thermal expansion and contraction of the inner and outer aluminum skins are synchronized; there are small holes on the honeycomb aluminum skin, so that the gas in the panel can flow freely; the slidable mounting buckle system will not cause structural deformation during thermal expansion and contraction.
Aluminum honeycomb core materials have excellent properties such as high wind pressure resistance, shock absorption, sound insulation, heat preservation, flame retardancy and high specific strength. In the 1960s, foreign countries have been used in various civil fields and developed rapidly. Aluminium honeycomb sandwich panel technology in China has been applied in various fields of civil industry. Aluminium honeycomb sandwich panel curtain wall has been widely used in high-rise building exterior wall decoration due to its many advantages such as light weight, high strength and high rigidity. The total thickness is 15mm, and the panel bottom plate is 1.0mm thick. The weight of the aluminium honeycomb sandwich panel with the same rigidity is only 1/5 of the aluminum veneer and 1/10 of the steel plate. The interconnected aluminum honeycomb core is like countless I-beams. The core layer is distributed and fixed in the entire panel surface, making the plate more stable. Its wind pressure resistance performance is much better than that of aluminum plastic plate and aluminum veneer, and it is not easy to deform and has good flatness. Even if the grid size of the aluminum honeycomb panel is large, it can achieve extremely high flatness and is the preferred lightweight material in the construction industry.
Features of aluminium honeycomb panel
1. Strong bearing capacity
The center is an aluminum hexagonal honeycomb with low density (about 3-7 kg per square meter), which is 1/5 of the weight of wood boards of the same thickness and area, 1/6 of glass, and 1/7 of aluminum, greatly reducing the building load and cost. Since the middle layer contains a lot of air, it can be soundproof (air sound insulation can reach 30dB) and heat-insulating (thermal resistance can reach 0.02 (㎡·K/W)), without flammable substances, the fireproof level reaches B1, waterproof, moisture-proof, no harmful gas release, unit mass It has high specific strength and high specific stiffness (the structural stiffness is 1.7 times that of the rib type), is not easy to deform, and completely overcomes the shortcomings of other decorative panels such as deformation and middle collapse when the single area is large. It is easy to process and use, and can be cut and folded at will. The fluorocarbon coating on the surface can ensure that the product life is more than 30 years. The surface of the honeycomb aluminium sheet has extremely high flatness and good seismic performance. It is only one-eighth of the specific gravity of the glass curtain wall; the load of 22mm thick standard parts can reach more than 700 kg when the deflection is 10mm and the simple support is 1 meter.
2. Corrosion resistance
The surface of the honeycomb aluminium sheet is treated with fluorocarbon resin with strong corrosion resistance, so that it can be widely used in the decoration of curtain walls, roofs, large facade signs and interior walls of buildings. The front aluminum plate of the honeycomb aluminium sheet adopts PVDF fluorocarbon paint that meets the E.C.C.A. quality standard and has excellent weather resistance. Honeycomb aluminium sheets have been widely used in building exterior wall decoration due to their light weight, high strength and high rigidity.
3. Energy saving
The weight of aluminium honeycomb sandwich panel with the same rigidity is only 1/5 of that of aluminum panels and 1/10 of that of steel panels. The weight of an aluminium honeycomb sandwich panel with a total thickness of 15mm, a panel of 1.0mm, and a bottom plate of 0.8mm is only 6 kg/m2. The interconnected aluminum honeycomb cores are like countless I-beams. The core layer is distributed and fixed in the entire panel surface, which is not easy to produce shear, making the panel more stable, more resistant to bending and compression. Its wind pressure resistance greatly exceeds that of aluminum-plastic panels and aluminum veneers, and it is not easy to deform and has good flatness. Even if the honeycomb panel is large in size, it can achieve extremely high flatness. Since the honeycomb core in the honeycomb aluminium sheet is divided into many closed chambers, the air flow is blocked, and the heat and sound waves are greatly hindered. Therefore, it has the effect of heat insulation, thermal insulation, and sound insulation. The sound source of 100-3200HZ can reach 20~30dB, and the thermal conductivity is 0.104-0.130W/M.K. Therefore, the energy absorption capacity of honeycomb aluminium sheet is 150-3500KJ/M², which is an ideal energy-saving material.
4. Strong weather resistance
In case of heavy rain, the noise is particularly loud when raindrops hit the aluminum veneer or aluminum-plastic panel, but honeycomb aluminium sheets avoid this situation. Aluminium honeycomb sandwich panel generally use fluorocarbon roll-coated aluminum panels as panels. The most important point of fluorocarbon roll-coated aluminum panels is that they use a continuous roller coating process. The painting of the aluminum plate is completed in one go, ensuring that the product has no color difference, good coating leveling, and reliable quality. At the same time, it can keep the color of the building‘s exterior wall bright for a long time. After long-term exposure to the sun and rain or industrial waste gas pollution, it is obvious that the roll-coated panel is cleaner and brighter than the spray-coated panel, and has good adhesion and weather resistance. It is recognized as a first-class material by world architects.
Applications of aluminium honeycomb panel
(1) Building curtain wall panels
(2) Interior decoration projects
(3) Billboards
(4) Shipbuilding

(9) For the modern furniture industry, which has strict environmental protection requirements, using aluminium honeycomb sandwich panel as furniture processing materials is a good material choice in the new century. Its completely non-toxic green quality allows furniture manufacturers to reduce unnecessary environmental protection procedures when processing furniture; in addition, aluminium honeycomb sandwich panel can be diversified, such as solid wood, aluminum panels, gypsum boards, and natural marble, which can all be made into honeycomb panels, making material selection convenient.
(10) Aluminum honeycomb panel partitions: The emergence of aluminum honeycomb panel partitions has broken the traditional partition model. With its noble, fresh and stylish style, it has won a market share in mid- and high-end office spaces.
