Introduction of barbed wire:
Barbed wire is an isolation and protective net made by a fully automatic barbed wire machine that wraps the barbed wire on the main wire (strand wire) and undergoes a variety of weaving processes. Commonly known as Tribulus terrestris, barbed wire, barbed wire.
There are three twisting methods of barbed wire: forward twist, reverse twist, forward and reverse twist.
Positive twisting method: It is to twist two or more iron wires into a double-strand wire rope and then wrap the barbed wire around the double-strand iron wire.
Anti-twisting method: firstly wrap the barbed wire around the main wire (that is, a single wire), then add another wire and twist it into a double-strand barbed wire.
Positive and negative twisting method: It is twisting in the opposite direction from the direction where the barbed wire wraps the main wire. Not twisting in one direction.
