The center is aluminum hexagonal honeycomb with small density, which greatly reduces the building load and cost. since the middle sandwich contains a lot of air, sound insulation, heat insulation, non-combustible material, the fire prevention level reaches B1 level, waterproof, moisture-proof, no harmful gas release, the specific strength, specific stiffness of unit mass is high, and it is not easy to deform.
The center is aluminum hexagonal honeycomb with small density, which greatly reduces the building load and cost. since the middle sandwich contains a lot of air, sound insulation, heat insulation, non-combustible material, the fire prevention level reaches B1 level, waterproof, moisture-proof, no harmful gas release, the specific strength, specific stiffness of unit mass is high, and it is not easy to deform. It completely overcomes the deformation and middle of other decorative panels in large single area. The surface of aluminum honeycomb board has high smoothness and good seismic performance. The surface is treated by fluorocarbon resin with strong corrosion resistance, which can be widely used in the ceiling of buildings.
