Complete Product Introduction of Metal Composite Plate (Steel Calcium Plate)

English name: METAL COMPOSITE PANEL

1、 Product definition and composite structure

1. Basic substrate

Using asbestos free calcium silicate board/fiber-reinforced cement board as the core layer, the substrate itself is A1 grade non combustible inorganic board, with stable chemical properties, moisture and mold resistance.

2. Metal surface layer (standard for steel calcium plate)

The surface is coated with 0.4-0.6mm thick aluminum zinc steel plate, and the surface is sprayed with fluorocarbon paint and inorganic enamel weather resistant coating, greatly improving the anti-corrosion, scratch resistance, and decorative effects.

3. Composite molding process

Through high-temperature pressure and static pressure curing integrated composite molding, the interlayer bonding strength of the board is ≥ 0.5MPa, and it will not open or delaminate after long-term use, with a stable and firm structure.

2、 Three core product features

1. Top level fire and moisture resistance performance

The substrate belongs to A1 level non combustible material, which does not produce toxic smoke in a fire environment, has a high fire resistance limit, and is perfectly suitable for harsh fire prevention places such as tunnels and subways; The overall service life of the product can reach 20-30 years, with a moisture expansion rate of less than 10% for the board. It is not easy to mold or deform in damp or underground environments.

2. High strength impact resistance mechanical properties

The flexural strength of the board is 28-50MPa, and only 9mm thick steel calcium board can replace 15-20mm ordinary fiber cement board; Excellent impact resistance, with no debris splashing or falling after vehicle or heavy object impact, and a higher safety factor for underground tunnel passage.

3. Environmental protection and safety, no light pollution

The entire process is asbestos free and formaldehyde free, meeting the national green building materials standards; The board surface adopts diffuse reflection matte treatment, which will not produce strong light glare, ensuring the visual safety of vehicles and pedestrians in tunnels and subways.

3、 Selection distinction between steel calcium plate and aluminum calcium plate

1. Steel calcium plate (mainly for tunnel transportation) has lower cost and stronger impact resistance, suitable for scenarios such as tunnels, underground tracks, and underground garages that require high-strength impact resistance (a classic application case of Shanghai subway tunnels).

2. Aluminum calcium board (exterior wall decoration) has a lighter weight and better acid and alkali corrosion resistance, and is commonly used for building exterior walls and indoor ceiling decoration; The actual selection shall be subject to the requirements of the project drawings and working conditions.

4、 Full scenario application scope

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

5、 Product standard specifications

Standard spot size: 2440 × 1220mm. Regular board thickness: 6-12mm. Customization of non-standard length, width, and special thickness sizes is supported according to project requirements.

6、 Steel calcium board compared to traditional materials (aluminum-plastic panel, stone)

1. Lighter self weight: Compared to stone, it significantly reduces building loads and has lower transportation and lifting costs;

2. Convenient construction: on-site cutting and slotting processing, suitable for curved and irregular wall surfaces;

3. Higher fire rating: A1 level non combustible standard, aluminum-plastic panel only B1 level, with obvious advantages in fire safety acceptance for underground projects;

4. Stronger safety protection: It will not shatter or splash when impacted, and the risk of using enclosed underground spaces is lower.
