Aluminium Composite Panel Manufacturers & Suppliers in China since 2002 - Henglicai ACP
Aluminium composite panels have become a popular material in the construction industry due to their lightweight, durability, and flexibility. They are made up of two aluminium sheets bonded together by a non-aluminium core material, resulting in a panel that is both sturdy and lightweight. One of the key benefits of aluminium composite panels is their high weather resistance. In this article, we will explore what makes aluminium composite panels so resistant to harsh weather conditions.
Aluminium Composite Panels and their Composition
Aluminium composite panels consist of two outer layers of aluminium, which are typically around 0.5mm thick, and a core material that is usually made up of polyethylene (PE), mineral-filled fire-resistant (FR) core, or metallic core. The aluminium sheets are coated with a protective layer that is scratch and weather-resistant. The thickness of the panels varies between 2mm and 6mm depending on the application.
The outer layer of aluminium is usually coated with various coatings such as polyester, PVDF, and FEVE to increase its weather resistance and durability. The coating protects the surface of the panel from environmental factors such as UV radiation, moisture, and pollutants.
When it comes to weather resistance, the composition of the panel is essential. The quality of the core material affects the panel's ability to withstand weather conditions. The core is usually made of PE, which is a low-cost, lightweight, and easy to work with material. However, this material is not suitable for areas prone to harsh weather conditions such as strong winds, heavy rain, and snow. Mineral-filled FR core and metallic core are more suitable choices for areas with such harsh weather.
Key Features of Aluminium Composite Panels
1. Durability
Aluminium composite panels are highly durable, resistant to chipping, cracking, and peeling. The materials used to make the panels offer excellent resistance to environmental factors such as sunlight, acid rain, and high temperatures. As a result, the panels maintain their appearance and functionality even after years of exposure to different weather conditions.
2. Lightweight
Aluminium composite panels are lightweight, making them an ideal choice for large structures that require less weight. The panels are easy to install and can be used in a range of applications, including cladding, signage, and partitions.
3. Easy to Fabricate
Aluminium composite panels are easy to fabricate, with the ability to be cut, routed, and bent into various shapes. This makes them ideal for designing unique and complex structures.
4. Aesthetic Appeal
The panels are available in various colors, finishes, and textures, making them a versatile material that can be used for different applications, including architectural, commercial, and industrial.
5. Energy-efficient
Aluminium composite panels are energy-efficient as they can help reduce energy consumption by insulating the building, reducing air leakage, and providing excellent thermal insulation.
How Aluminium Composite Panels Achieve High Weather Resistance
1. UV Resistance
The outer layer of the aluminium composite panel is coated with a suitable coating that provides excellent UV protection. The coating protects the panel from UV radiation, which can cause the panel's color to fade, peel, or crack. The coating prevents the transfer of harmful UV rays to the underlying layers of the panel, keeping it looking great for longer.
2. Thermal Expansion
Aluminium composite panels can expand or contract due to temperature changes. This is known as thermal expansion. To combat this, the panel's outer layer is designed to accommodate such changes without affecting the panel's functionality or integrity.
3. Moisture Protection
Aluminium composite panels are sealed tightly to prevent moisture from penetrating the panel's core. The panels have a layer of moisture-resistant backing that keeps water and other liquids from seeping through the panel. This makes them ideal for use in areas prone to heavy rainfall or frequent exposure to moisture.
4. Corrosion Resistance
Aluminium composite panels are highly resistant to corrosion, which is caused by a chemical reaction between metal and an oxidizing agent. The panels are coated with a protective layer that prevents corrosion by shielding the underlying metal from the oxidizing agents, such as oxygen and water.
5. Impact Resistance
Aluminium composite panels are highly resistant to impacts and dents. The panels are tested for impact resistance to ensure that they can withstand high winds, hail, and other severe weather conditions.
Conclusion
Aluminium composite panels come in a range of sizes, colors, and finishes, and are ideal for use in a range of applications, including architecture, commercial buildings, industrial buildings, and even signage. Their lightweight, durability, and flexibility make them a popular choice for construction projects around the world. With excellent weather resistance, the panels can withstand harsh weather conditions and maintain their appearance and functionality for years to come.
