    Classified by twist method

    The barbed wire is a kind of isolation protective net formed by winding the barbed wire on the main wire (strand wire) through a variety of weaving processes.

    Three methods of twisting the thorn rope: forward twisting, reverse twisting, reverse twisting.

    • Positive twist method: It is to twist two or more pieces of wire into a double wire rope and then wrap the barbed wire around the double wire.
    • Reverse twisting method: it is to wrap the nematous wire around the main wire (that is, a single iron wire) and then add an iron wire and twist together into a double strand of barbed rope.

    Positive and negative twisting method: from the nematocyst winding main wire direction opposite to the direction of twisting. It's not twisted in one direction.

    Processing classification

    The reason to do surface treatment is to strengthen the anti-corrosion strength, prolong the service life. Galvanized barbed rope as the name suggests that the surface treatment is galvanized, can be galvanizing and hot dip galvanizing; PVC barbed wire for surface treatment is PVC plastic coated treatment, the inside barbed wire for black wire, electroplating wire and hot plating wire.
