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.
Aluminized steel Aluminized steel Aluminized steel is steel that has been hot-dip coated on both sides with aluminium-silicon alloy. This process assures a tight metallurgical bond between the steel sheet and its aluminium coating, producing a material with a unique combination of properties possessed neither by steel nor by aluminium alone. Aluminized steel shows a better behavior against corrosion and keeps the properties of the base material steel for temperature lower than . For example, it is commonly used for heat exchangers in residential furnaces, commercial rooftop HVAC units, automotive mufflers, ovens, kitchen ranges, water heaters, fireplaces, barbecue burners, and baking pans.
