Barbed Wire is a traditional protection fencing material with steel wires twisted with a system of constant torsion, usually in multiple strands, with barb prongs interlaced in the wires.
The strands are usually coated with a protective material such as galvanized steel or plastic to prevent rusting and corrosion. Barbed wire is often used as livestock fencing around farms, ranches, and security fencing for airport, power plant and other properties.
Installation Ways
Two ways of using barbed wires:
1, Barbed wire fencing of the barbs and the posts / poles. The barb wires are secured to the posts. Posts are typically made of galvanized steel, or plastic coated steel and they are used to support the lines of barbed wire. Posts can be of various sizes and shapes, depending on the size and configuration of the fence.
2, Barbed wire with chain link fence, welded mesh fence, and various steel tubular fences.
2 rows, 3 rows, 4 rows or 6 rows of Barbed wire rolls or coils are fixed at top rails of the fence panels and gates via v arms support.
