Precast Concrete Composite lab Molds Precast Concrete Composite Slab Molds are composed of prefabricated panels and cast-in-place reinforced concrete. Precast Concrete Composite Slab Molds has good integrity, and the surfaces of the slab are flat, which is convenient for the decoration of the veneer. Precast Concrete Composite Slab Molds are suitable for high-rise buildings and large-width open buildings with high requirements on overall rigidity. Precast Concrete Composite Slab Molds are not only one of the components of the slab structure, but also a permanent template for the cast-in-place reinforced concrete laminate. Horizontal equipment pipelines can be laid in the cast-in-place laminate. Prestressed composite slab combine the advantages of prefabricated and cast-in-place slabs. The span of the composite slab is generally 4~6m, and the maximum span can reach 9m. The thickness of a composite slab varies depending on the span of the slab. The composite slab
