Galvanized Barbed Wire is a fencing wire made from galvanized steel wire twisted with sharp barbs at fixed spacing. It is used for farm fencing, pasture boundaries, property lines, industrial perimeter fences, and fence-top security. The zinc coating helps reduce rust during outdoor use. Common supply forms include coils by length or weight. Buyers usually choose the product by wire diameter, barb spacing, twist type, zinc coating level, coil length, and packing method. Galvanized Barbed Wire can be installed with wooden posts, steel posts, concrete posts, chain link fences, welded mesh fences, or wall-top brackets.
Material: Low carbon steel wire or high tensile steel wire with galvanized surface treatment.
Galvanizing Type: Electro-galvanized or hot-dipped galvanized. Hot-dipped galvanized wire is commonly selected for outdoor fencing with longer exposure.
Line Wire Diameter: Common diameters include 1.6mm, 1.8mm, 2.0mm, 2.2mm, 2.5mm, and 2.8mm.
Barb Wire Diameter: Common barb wire diameter ranges from 1.5mm to 2.2mm, depending on the main wire size.
Barb Spacing: Common spacing includes 75mm, 100mm, 125mm, and 150mm.
Twist Type: Single twist or double twist. Double twist is widely used for farm fencing and general perimeter lines.
Coil Length: Common lengths include 50m, 100m, 200m, 250m, and 500m.
Coil Weight: Common coil weights include 10kg, 20kg, 25kg, and 50kg. Weight depends on wire diameter and coil length.
Tensile Grade: Low carbon steel is used for easier handling and general fencing. High tensile wire is used where longer fence spans or stronger tension are required.
Surface Finish: Bright galvanized or dull galvanized finish, depending on zinc coating method and production batch.
Packing: Coil packing with steel tie wire, plastic film, woven bag, carton, pallet, or wooden reel.
Installation Method: Fixed to fence posts with staples, clips, tie wire, strainers, or tension wire.
