Barbed Wire is a fencing material made from steel wires twisted together with sharp barbs placed at regular intervals to provide security and boundary protection. It is manufactured in various wire diameters, barb spacing, and coil sizes as per standard specifications, offering strength, durability, and resistance to tampering. Barbed wire is identified by its wire gauge, coating type (GI/PVC), and coil length, with weight based on wire thickness and coil size.
