Barbed security fencing is made from cold-drawn low-carbon steel wire, welded and hot-dip galvanized. The wires are thicker than standard farm fencing, which gives better impact resistance. It is used for perimeters around warehouses, storage yards, industrial sites, and utility substations.

Product Advantages
The barbed security fencing uses cold-drawn wire, which has higher hardness and tensile strength than ordinary hot-rolled wire. Hot-dip galvanizing with 220–300 g/m² zinc provides corrosion resistance suitable for outdoor use in most climates. The barbed design – with dense, sharp barbs – makes climbing or cutting difficult. We test each batch for tensile strength and zinc coating thickness using standard equipment (universal tester and magnetic gauge). Production follows ISO 9001 procedures, though we do not claim unrealistic test results.
