Barrier cable Barrier cable Barrier cable is a vehicular or pedestrian restraint system used in parking garages. It installed along the ramps or around the perimeter of the parking structure. It consists of a 0.5-inch, 7-wire steel strand which is similar to the strand used in Post-tensioned concrete. There are three types of barrier cables systems: Galvanized barrier cable is the most prevalent type of barrier cable used today. The steel strand is Zinc plated to protect it from corrosion per ASTM A475. Epoxy-coated barrier cable is used on occasion for aesthetic purposes. It is significantly more expensive than galvanized barrier cable.
PC strand well as 1720, 1770, 1960, 2000, 2100 MPa and the like intensity levels. The yield strength of this steel is also higher. In most of the post-tensioned and pre-tensioned prestressed project, smooth steel strand is the most widely used prestressed steel. Stranded strand is mainly used to enhance the project, but also for nuclear power and the like works. Galvanized steel strand commonly used in the bridge of the tie rod, cable and external prestressing works. Epoxy coated steel stranded wire is similar to galvanized prestressed steel wire. Countries have standards for prestressed strand, such as: China Standard GB /
