Product description:
the surface of the metal carved board/panels(metal engraved board/panels) is a high-quality metal plate overcoating with colored relief after special coating treatment, the middle layer is a hard high density polyurethane foam thermal insulation layer treated by flame retardant treatment, the underside is the aluminum foil protective layer which plays the role of thermal/heat insulation and moisture-proof.
the wall panel has the characteristics of thermal insulation, waterproof and flame-retardant, light earthquake resistance, sound insulation and noise reduction, green environmental protection, beautiful and durable, and the assembly method of the board body is simple, convenient construction, and it is not limited by the season or environment, the four seasons are appropriate.

Material of surface: the outer layer is a metal layer, which is pressed by a galvalume steel sheet (Containing 55% aluminum, 43% zinc) and is not rusted all year- round. the steel coating is coated with high-quality Nippon paint, which is durable and does not fade.
Core material: the hard high-density polyurethane foam thermal insulation layer treated by flame retardant treatment, set heat preservation, fire-proof, moisture-proof, high hardness in one, which is incomparable with ordinary foam polyurethane.
Material of bottom: the back of the metal carved board is the aluminum foil protective layer with excellent water-proof performance, which can effectively block the intrusion of water vapor into the board and build a wall, and reflect the heat source of the house to enhance the heat preservation effect.

Advantage:
1. Heat preservation and heat insulation: the metal carved board has excellent heat preservation and heat insulation performance, can greatly reduce the heating and cooling energy consumption, and save energy expenditure, compared with the traditional exterior wall heat preservation materials, the product cost performance is higher.  
2. Fire and flame retardant: the surface of the board is made of a metal layer with special technology, and the inner core is made of hard high density polyurethane foam thermal insulation layer treated by flame retardant treatment. The bottom layer is fireproof and moisture-proof fiber cloth, which makes triple protection more secure.  
3. Waterproof and moisture-proof: Metal carved board has an excellent own structure and compact concave-convex bump plug between the board and groove type installation, it can avoid structural damage caused by rain, snow, freezing, melting, etc. It can eliminate the possibility of wall water seepage after installation.
4. Sound insulation and noise reduction: the core material in the middle of the metal carved board is heat preservation and a sound insulation layer composed of high-density polyurethane foam, and its internal is an independent closed bubble structure with a good sound insulation effect.
5. Efficient construction: the installation method of the metal carved board is simple and fast, regardless of being limited by seasonal climate and geographical environment. It can obviously shorten the progress of the project, save the construction cost and reduce the overall cost.  At the same time thermal insulation, minimizes the load on the exterior walls and increases the availability of space and land.
6. Environmental protection and durability: the metal carved board has a stable chemical and physical structure, it does not decompose and mildew, and it has no radiation and no pollution to our environment. It also can be flexible disassembly for reinstalled and reused, its scraps can also be recycled and reused, the construction waste will be reduced in the installation process, and easy to clean and durable.
7. Shock resistance and crack prevention: the metal carved board is light in weight, high in strength, and good in impact resistance.  the advantages of light weight, not only reduce the burden of the building itself, but also greatly reduce the impact of the earthquake on the building.  the board is installed in the lightweight steel structure of the building and has strong integrity, anti-knock and anti-crack, which performs strongly and is high in safety.
8. Strong decoration: the metal carved board has a combination of real relief patterns and rich colors, giving the architectural design greater space to play, highlighting its higher grade and elegant taste. the simple and flexible disassembly method, makes the replacement of the wall space design collocation easy.
