Aluminum-calcium board is a fire-resistant board commonly used for decoration in tunnels, subways, and public buildings. Currently, the wholesale prices vary depending on the thickness and craftsmanship, and are supplied by multiple building material manufacturers. This material combines the durability of metal with the fire resistance of inorganic boards, making it a popular choice in engineering decoration. ‌‌‌

Main features and performance

Strong fire and moisture resistance: Aluminum-calcium board typically meets Class A non-combustible standards, with a fire resistance limit of over 2 hours and no release of toxic smoke in case of fire. Its water absorption rate is extremely low (generally less than 5%), making it less prone to deformation or mold growth in humid environments, making it suitable for high-humidity areas such as bathrooms and basements.

High strength and durability: The board has high flexural strength, with some products reaching up to 28MPa, capable of withstanding certain impacts without cracking. The surface coating has undergone special treatment, making it resistant to acids, alkalis, and salt spray, with a design service life typically exceeding 20 years.

Environmental safety: The main components are inorganic minerals, free from harmful substances such as asbestos and formaldehyde. Some products also possess antibacterial properties, making them suitable for use in places with high hygiene requirements. ‌‌‌

Common application scenarios

Traffic tunnels and subways: Widely used for the interior decoration of subway tunnel side walls and urban road tunnels, it can effectively avoid driving glare and is resistant to exhaust gas corrosion.

Public and medical buildings: Applicable to hospital clean rooms, operating room walls, as well as school and hotel lobbies and corridors, meeting fire safety and easy-to-clean requirements.

Industrial and Special Environments: It can be used in high-temperature environments such as boiler rooms and power distribution rooms, as well as corrosive environments with salt spray, such as coastal areas
