Abstract
A pallet includes a rigid body that supports a concrete product and a polymer layer that corresponds to a geometry of the concrete product within a predetermined tolerance. One or more flanges with apertures are provided with the rigid body for the polymer layer to attach thereto. The polymer layer can extend outward from the rigid body to form a portion of the dimensions for the concrete product within predefined tolerances.
