Precast Double Wall
Composite wall panels (also known as: double wall panels) are composed of lattice girders that connect two layers of inner and outer plates with a thickness of 50-70 mm. The reinforcement of the wallboard is designed in strict accordance with the force requirements of the corresponding building. The laminated wall panels are semi-prefabricated components. After the site is installed in place, the gap between the two wall panels is filled with cast-in-place concrete, thereby turning the laminated wall panels into a solid solid wall panel. Precast double wall combines the advantages of industrial production with cast-in-place concrete. Precast double wall is widely used in above and underground structures of construction.
