Pre-stressed concrete walls are often produced on large steel molds, or on occasion, on FRP surfaces.
Recently, a major US concrete manufacturer evaluated WB-CONC in the production of large pre-stressed
concrete sheets. The mold in this case was a 600 foot long (182.9 meters) and 8 foot wide (2.44 meters)
sheet of steel. Production involves stretching steel cables across the length of the slab; setting partitions to
segment the large mold into the appropriate length slabs; and casting concrete. Before any of this occurs,
mold release is applied to the huge steel mold with long handled mops or floor buffers.
