1、 Product definition and composite layered structure

Aluminum calcium board belongs to inorganic core metal composite decorative board, which is composed of inorganic fireproof core material and aluminum alloy surface layer high-temperature composite:

1. The core substrate adopts asbestos free calcium silicate board/fiber-reinforced cement board. The substrate is originally A1 grade non combustible, chemically stable, moisture-proof and mildew proof.

2. The surface of the metal finishing layer (exclusive for aluminum calcium plate) is compounded with 0.4 – 0.6mm aluminum alloy sheet, and the plate surface is sprayed with fluorocarbon paint and inorganic enamel weather resistant protective coating, greatly improving the acid and alkali corrosion resistance, outdoor aging resistance and decorative texture.

3. The integrated composite process involves high-temperature pressure and static pressure curing to form a multi-layer composite. The interlayer bonding strength of the board is ≥ 0.5MPa, and it will not open or delaminate after long-term use. The overall structure is firm and stable.

2、 Three core product performance characteristics

1. A1 level fire protection, long-lasting moisture resistance

The substrate is made of A1 grade non combustible material, which does not spread or produce toxic smoke when exposed to open flames. Its fire resistance limit meets the strict fire safety standards of tunnels, hospitals, and public buildings; The moisture expansion rate of the board is less than 10%, it is moisture-proof and mold proof, and can be used stably in damp, underground, and coastal environments. The overall service life can reach 20-30 years.

2. Lightweight and high-strength, with safer impact resistance

The flexural strength of the board is 28-50MPa, and thin aluminum calcium board can replace thicker fiber cement board; No debris splashes after heavy objects or vehicle collisions, avoiding the risk of falling off and injuring people; Compared to steel calcium board, it has a lighter weight and significantly reduces the load on building walls, making high-rise exterior walls and ceiling construction safer.

3. Green and environmentally friendly, anti glare and no light pollution

The entire process is asbestos free and formaldehyde free, meeting the standards of green building materials; The board surface adopts diffuse reflection matte technology, which will not form strong light glare. Spaces such as subways, tunnels, and hospital corridors can ensure visual safety for pedestrians and drivers.

3、 Differences in selection between aluminum calcium plate and steel calcium plate

1. Advantages of aluminum calcium sheet: lighter weight, stronger acid and alkali corrosion resistance; Applicable scenarios: Building exterior wall curtain walls, indoor ceilings, coastal high corrosion, and damp decoration projects;

2. Advantages of steel calcium plate: lower cost and superior impact resistance; Applicable scenarios: high impact underground transportation projects such as tunnels and subways; The final selection needs to be determined based on the project drawings and operating conditions.

4、 Full scenario application scope

1. The lining of tunnel sidewalls, subway platforms, and airport passages in transportation infrastructure projects should take into account fire prevention, noise reduction, and aesthetic decoration;

2. High end exterior wall curtain wall for office buildings, villas, and commercial complexes, with lightweight and weather resistant exterior wall panels preferred.

5、 Product standard specifications

Standard spot size: 2440 × 1220mm Regular thickness range: 6-12mm Supports customized non-standard length and width, special thickness sizes, suitable for irregular shaped projects.

6、 Compared to traditional materials (aluminum-plastic panels, natural stone)

1. Self weight advantage: lighter than natural stone, reduces building load-bearing capacity, and lowers transportation and lifting costs;

2. Convenient construction: on-site cutting, slotting, bending to create curved shapes, with high assembly efficiency;

3. Higher fire rating: A1 level non combustible standard, far superior to B1 level aluminum-plastic panels, with outstanding advantages in fire safety acceptance for public and underground projects;

4. Safe and durable: The impact will not shatter or splash, and the aluminum alloy surface layer is weather resistant and corrosion-resistant. It is not easy to powder or fade after long-term outdoor use.
