1. Light weight: 10-14kg / m2, equivalent to 1 / 30 of the brick wall.
2. Thermal insulation: thermal conductivity of core material: λ < = 0.041w/mk.
3. High strength: it can be used as the load-bearing, bending and compression resistant board of the ceiling enclosure structure; generally, the house does not use beams and columns.
4. Bright color: there is no need for surface decoration, and the retention period of anticorrosive coating of color galvanized steel plate is 10-15 years.
