Aluminum honeycomb panel is a new type of environmentally friendly composite decoration material. It adopts a honeycomb sandwich structure, composed of double-layer panels, double-layer adhesive layers and aluminum honeycomb core. It is mainly used in the field of civil construction. The outer surface of honeycomb aluminum panels can be subjected to a variety of surface treatments to achieve different appearance effects, such as spraying, aluminum plating, galvanizing, oxidation, etc. Aluminum honeycomb panel has good sound insulation and heat insulation functions. Its wind resistance and pressure resistance far exceed that of aluminum plates and aluminum-plastic composite materials, and its flatness is extremely high. So, what is the reason why aluminum honeycomb sheets are widely recognized?
Structural Composition Of Aluminum Honeycomb Panel:
Aluminum decorative panels honeycomb aluminum sheet decorative panels are generally made of alloys such as aluminum 3003 and aluminum 5005. Aluminum 1100 sheets with low alloy composition are rarely used. The decorative surface is sprayed or rolled, and the coating is polyester or fluorocarbon paint.
Honeycomb core material is made of aluminum foil and special honeycomb node glue on an aluminum honeycomb core production line. Generally, 3004-h18 aluminum foil or 3004-h19 aluminum foil is used. The factors that affect the performance of honeycomb core aluminum materials mainly include aluminum foil, node glue and honeycomb core’s specifications and other parameters.
The aluminum back sheet aluminum honeycomb sheet should be made of the same material as the panel. The surface should be anodized. The side exposed to the air should be coated with a protective coating. The coating material can be polyester, epoxy, acrylic and other materials to prevent Long-term exposure to air causes corrosion of aluminum plates.
Aluminum Honeycomb Panel Manufacturing Processing:
The specific process flow of aluminum honeycomb panels are as follows:
Preheat → grind and brush the aluminum plate clean → spray structural adhesive and heat up → lay the honeycomb aluminum core → maintain pressure → cut semi-finished products → dry → bond and install.
While satisfying a series of technological processes, related equipment is required for supporting use. The equipment used in the test is a hot press and large-size aluminum honeycomb panel production equipment.

Disadvantages of Honeycomb Aluminum Panel:
- High cost: Manufacturing honeycomb structures requires additional processing steps and materials, resulting in increased production costs.
- Poor repair ability: The particularity of the honeycomb structure makes it impossible to simply repair a single unit if the aluminum honeycomb panel is damaged or destroyed.
- Response force concentration: When external loads or impacts act on the surface of the honeycomb panel, the stress may cause excessive local sound.
- Difference in thermal expansion coefficient: The outer layer and aluminum core of aluminum honeycomb panels have different thermal expansion coefficients. Thermal stress and deformation may occur during temperature changes.
- Single shape: The honeycomb panel material is relatively hard and difficult to make special shapes.
Applications Of Aluminum Honeycomb Panels:
Building curtain wall decoration: Aluminum honeycomb panels are lighter in weight than traditional building decoration materials such as stone and concrete. It has a flat and smooth surface and can be customized with different colors, textures and surface treatments according to design requirements, covering the building exterior walls. The honeycomb core inside the aluminum honeycomb panel has excellent thermal insulation properties. It can effectively reduce heat conduction between the building and the outside environment. And aluminum honeycomb panels are usually made of materials with good fire resistance, such as aluminum alloy. This material has good fire resistance and can effectively resist the spread of fire.
Furniture honeycomb panels: Aluminum honeycomb panels have good corrosion resistance and deformation resistance, and can withstand long-term use and environmental impact. The honeycomb structure also provides thermal insulation and sound absorption properties, reducing noise and heat conduction on the furniture surface.
Ceiling: Aluminum honeycomb panels have the characteristics of lightweight, high strength, durability, sound insulation, fire protection, etc., which can extend the service life and provide additional safety guarantee.
Elevator engineering: Aluminum honeycomb panels can be used for interior decoration of elevators, including wall panels, ceilings, floors, etc. In elevator engineering, lightweight aluminum honeycomb panels can reduce the overall weight of the elevator. Aluminum alloy materials have good corrosion resistance.
Rail transit: Within rail transit, honeycomb panels are used to decorate car ceilings, doors, walls and other parts. It can also be used as body panels, with lightweight, high strength, vibration resistance and corrosion resistance. The honeycomb structure also provides high rigidity, helping to enhance the structural strength and stability of the entire vehicle.
Installation And Maintenance Of Aluminum Honeycomb:
Installation: First make sure the installation surface is dry, flat and clean. Aluminum honeycomb panels are measured and cut to relevant specifications and exact dimensions before installation. Sealing materials or tapes can be used to avoid moisture penetrating the joints between panels using mechanical fixing systems or bonding techniques, following detailed guidance and recommendations provided by the manufacturer.
Maintenance: Clean the surface of the aluminum honeycomb panel regularly to remove dust, oil and other stains. Do not use harmful substances such as abrasives, strong acids or alkalis to avoid damaging the surface coating; regularly check the fixing system of the aluminum honeycomb panel.
How To Select High Quality Aluminum Honeycomb Panels:
Select the thickness of the honeycomb core. The thickness of the honeycomb core is 7mm~9mm. The honeycomb core used for suspended ceilings generally uses honeycomb cores with a side length of 5~6mm. The greater the density, the stronger the resistance to external forces, the more support points, and the flatter the board surface will be. It can effectively absorb impact energy, play the role of shock absorption and anti-collision, thereby protecting the wall from damage.
Check whether the manufacturer has a supporting construction plan that matches the product, as well as a formal national quality inspection report and environmental protection label.
The aluminum material is made of raw aluminum, which is not prone to unevenness, pits, etc. and ensures a smooth surface.
Check the flatness by carefully feeling it with your hands. There should be no dents or bulges on the surface of the aluminum alloy. The surface of qualified wall panels should be smooth and bright with good gloss.
From a technical point of view, good aluminum honeycomb panels have small gaps at the joints, no defects, and good appearance.
Look at the surface craftsmanship. Generally, the cheaper ones are single-coated. Most of the ones on the market are double-coated. It is better to choose three coatings.
Aluminum Sheet vs Plastic Sheet vs Honeycomb Panel:
What is aluminum sheet?
The aluminum sheet is made of high-quality aluminium sheet material as the base material and is rolled into shape.
What is aluminum plastic sheet?
Aluminum plastic sheets refer to a three-layer composite panel with plastic as the core layer and aluminum on both sides. The surface of the product is covered with a decorative and protective coating or film (generally referred to as a coating unless otherwise specified). The decorative surface of the product.
What is honeycomb aluminum panel?
Honeycomb aluminum panels adopt a “honeycomb sandwich” structure, which is a composite panel made of high-strength alloy aluminum panels as the surface, bottom panel and aluminum honeycomb core through high temperature and high pressure.
The main difference between the three is: First of all, in terms of appearance, the aluminum sheet is one layer of aluminum alloy sheet, the aluminum plastic sheet is two layers of aluminum plates with PVC sandwiched between them, and the aluminum honeycomb is two layers of aluminum plates with honeycomb-shaped aluminum sheets sandwiched between them. In terms of cost, the manufacturing cost of aluminum honeycomb panels is the most expensive, followed by aluminum veneers, and finally aluminum-plastic sheets. If there are requirements at the processing level, the cost will change. Moreover, the production process of aluminum honeycomb panels and aluminum-plastic plates requires the production of waste materials, which results in higher costs.
