Rocksmith also stocks high quality galvanized flat ducts used for aiding post tensioning of concrete structures. Post tensioning is a technique for reinforcing concrete. It is a form of prestressing the concrete. Prestressing simply means that the steel strands are stressed (pulled or tensioned) before the concrete has to support the service loads.
LR strands are passed through these galvanized flat ducts and concrete is poured onto them as well as the rebar framework. Once the concrete has gained strength but before the service loads are applied, the cables are pulled tight, or tensioned, and anchored against the outer edges of the concrete.
