Spanwright produce precast reinforced, prestressed hollowcore and Block & Beam flooring units. Our technical department will be able to advise you which product is best for your particular application.
In general precast units are more economic for shorter spans (up to 6m) and light loading situations, eg Housing construction, while prestressed units can span longer distances and take heavier loads.
Block & Beams are more commonly used in ground floor construction over short spans and where access for heavy plant is limited
