These panels work well for both indoor and outdoor applications, including cladding, partitions, and signage.

Ordinary acp sheet panels offer a strong strength-to-weight ratio, easy installation, and resistance to weather and impact. Their lightweight nature reduces structural load and makes them suitable for high-rise buildings.

The core and surface materials differ among the different types of aluminum composite panels. Ordinary acp sheet panels use a standard polyethylene core, while other types may use mineral-filled or fire-retardant cores for added safety.

Fire-Rated ACP Sheets

Fire-rated acp sheet panels use a special core made from mineral materials, such as alumina trihydrate or magnesium hydroxide. This core limits flame spread and reduces heat release during a fire. The aluminum layers and fire-resistant coatings further improve safety.

Scientific studies show that fire-rated acp sheet panels control fire propagation much better than standard panels. In large-scale fire tests, fire-rated panels kept flame heights under 10 feet and peak heat release rates below 1 MW. Standard acp sheet panels, by comparison, allowed flames to reach over 25 feet and heat release rates above 6 MW. The fire-resistant core and charring insulation layers make these panels a safer choice for buildings that require strict fire safety standards.

Fire-rated acp sheet panels meet international fire safety codes and are often required in high-rise buildings, hospitals, and schools.

Mirrored ACP Sheets

Mirrored acp sheet panels have a reflective surface finish that mimics the look of glass or polished metal. The core structure remains similar to ordinary acp sheet panels, but the outer aluminum layer receives a special mirror coating. This finish creates a striking visual effect and adds depth to architectural designs.

Mirrored acp sheet panels are lightweight and easy to install. They resist corrosion and maintain their shine over time. Designers often use these panels for interior decoration, signage, and building facades where a modern, reflective look is desired.

Honeycomb Panels

Honeycomb panels use a unique core made from aluminum arranged in a honeycomb pattern. This design reduces weight by up to 30% compared to solid panels, while increasing stiffness and strength. The honeycomb core absorbs energy and resists bending, making these panels ideal for demanding structural applications.

• Research shows that honeycomb panels maintain high stiffness and strength after repeated load cycles.
• The honeycomb core mass should be about 50–66.7% of the total panel mass for optimal performance.
• Honeycomb panels offer better energy absorption and bending stiffness than many commercial products.

The lightweight nature of honeycomb panels makes them suitable for large surfaces, ceilings, and furniture. Their structure also provides excellent sound and thermal insulation.

Metal Composite Panels

Metal composite panels, often called MCM panels, use two thick metal skins bonded to a plastic or fire-retardant core. While aluminum is the most common metal, some panels use steel or copper for added strength or visual appeal. The composite structure gives these panels superior mechanical properties compared to solid metal sheets.

Metal composite panels offer high dimensional stability, increased modulus of elasticity, and improved rupture strength. The use of thick metal skins and advanced bonding techniques results in panels that resist swelling, expansion, and mechanical stress. These panels are often chosen for projects that require extra durability, impact resistance, or unique metal finishes.

Metal composite panels stand out among the different types of aluminum composite panels for their strength, versatility, and ability to meet demanding architectural requirements.

Material and Manufacturing Differences

The different types of aluminum composite panels use a variety of core and surface materials to meet specific needs. Some panels use low-density polyethylene, while others use mineral-filled or fire-retardant cores. The aluminum skins may receive coatings such as PVDF, FEVE, or polyester paint, and can be finished in many colors and patterns. These differences in material composition affect fire resistance, durability, and appearance.

These manufacturing differences play a key role in the quality, safety, and versatility of the different types of aluminum composite panels. Advanced production methods allow for better fire resistance, improved finishes, and more sustainable products.
