A2 Fire-Resistance & Non-Combustible Aluminium Composite Panel
The Alucobang A2 fire-retardant & non-combustible aluminum composite panel is a new-generation decorative material designed for wall cladding and architectural façades. Made with inorganic mineral core materials such as calcium hydroxide and magnesium hydroxide, it contains no organic components and offers outstanding non-combustibility. Complying with GB8624-2012 Class A2-s1,d0,t0, it ensures no open flame, no molten drips, and minimal smoke emission — providing reliable protection and extended safety time during fire emergencies.
Fire Performance of Alucobang Aluminium Composite Panels
In aluminium composite panels, the core material is the key factor determining the fire safety level of the building. Alucobang panels are available in B1+, FR, HFR, and A2 flame-retardant grades, each providing different levels of fire protection according to application needs. Tested and certified by authoritative organizations such as SGS and INTERTEK, our products meet multiple international fire safety standards with proven reliability.

Key Features of Alucobang Class A2 Fire-Retardant & Non-Combustible Aluminum Composite Panels
Designed for safety, durability, and performance — fire-resistant, eco-friendly, and long-lasting.
Class A Fire-Retardant & Non-Combustible Property
It adopts high-quality inorganic and environmentally friendly core material, complying with the national Class A2 fire-retardant and non-combustible standard. It has good resistance to high and low temperatures, does not allow fire to spread when exposed to flame, effectively blocks fire, and meets the requirements of building fire protection regulations.
Excellent Water and Moisture Resistance
The panel has a dense structure; both the core material and aluminum sheet have good water resistance and moisture resistance. Even when in a high-humidity environment for a long time, it is not easy to deform, crack or mildew, making it suitable for various damp indoor and outdoor occasions.
Efficient Sound and Heat Insulation
The composite structure of the core material and aluminum base sheet has excellent sound insulation and heat insulation performance. It can reduce external noise interference, while minimizing the conduction of temperature differences between the interior and exterior of the building, helping to improve space comfort.
Superior Weather Resistance
The high-performance PVDF fluorocarbon coating based on KYNAR500 has excellent corrosion resistance, pollution resistance and weather resistance. Whether in extreme heat or severe cold, it can maintain a brand-new and attractive appearance.
Impact Resistance & Bendable
It has strong impact resistance and high toughness; bending will not damage the topcoat. When facing external collision or impact, it can maintain structural stability and has excellent resistance.
Environmentally Friendly & Pollution-Free
It is halogen-free and low-smoke; the material is difficult to burn and produces extremely low smoke. When burned, it does not generate corrosive gas or black smoke, is non-toxic and harmless, and complies with the national green and environmentally friendly building material standards.
Comparison of Fire Resistance Tests
Alucobang aluminium composite panels undergo a series of standardized fire resistance tests to evaluate flame spread, heat release, smoke production, and toxic gas emissions. Each classification level—B1, FR, HFR, and A2—is verified through laboratory testing under national and international standards, ensuring reliable fire safety performance for different building applications.
Ordinary PE Aluminum Composite Panel
It burns easily, and the flame continues to burn after the fire is turned off.
Class B1 Fire- Resistance Aluminum Composite Panel
There are faint sparks, the flame stays on the surface, the flame slowly extinguishes after the fire is turned off, there is residual ash on the surface, and there is no obvious sign of collapse in the internal structure.
Class A2 Fire- Resistance Aluminum Composite Panel
No signs of combustion, no obvious burning signs, and the internal structure remains intact.
Application of Class A2 Fire-Resistance & Non-Combustible Aluminium Composite Panel
Alucobang Class A2 fire-retardant and non-combustible aluminum composite panels are widely used in public and commercial buildings with high fire safety requirements, such as the exterior and interior wall decoration of commercial complexes, hotels, schools, hospitals, laboratories, clean workshops, rail transit stations, and high-end residential buildings.
