Prestressed slab is refers to in the production process of reinforced by the applied tensile stress on to prevent the plate at work by pull parts of the concrete cracks and also give full play to the role of tensile reinforcement, steel saving.

Reinforced concrete floor is a structure made of concrete with reinforced concrete. The main components of the bearing are made of reinforced concrete. Including the thin shell structure and large formwork cast-in-place structure and the use of sliding mode, lift slab constructed of reinforced concrete structures of buildings.

Prestressed concrete slab with high price, complicated construction and high bearing capacity, the construction of the reinforced concrete floor is simple, the cost is low, and the carrying capacity is slightly worse. Their integrity is very good, can be cast in place. The biggest advantage of the prestressed concrete floor is the strong ability to resist dynamic load. Generally used in bridges, public buildings, such as cinema, stadium.

Cast-in-place reinforced concrete slab is cast in site, which is characterized in that the firm structure, easy buried line pipe, good integrity; but the amount of material and the construction speed is slow, soundproof performance difference.

Prestressed floor is generally hollow board, is made in the field of the production of the completion of the direct installation on the line, the characteristics are: construction speed, sound insulation effect, saving raw materials.
