These alternate types tend to be more expensive or have lesser mechanical properties and are thus more often used in specialty construction where their physical characteristics fulfill a specific performance requirement that carbon steel does not provide.

Most commercially available rebar is made from unidirectional fibers set in a thermoset polymer resin, and is often referred to as FRP. Requirements for deformations on steel bar reinforcement were not standardized in U. The carcass of the tower was connected to its cast iron tented roofcrowned with one of the first known lightning rods.
