*A defensive measure against rust that coats metals with zinc. This coat of zinc helps reduce exposure to humidity, salt air, and other chemicals. *All Red Brand Barbed Wire comes in a length of 1,320 feet. That’s the equivalent of one-quarter mile, or one side of a square 40-acre parcel. *Red Brand makes two styles of barbs - Defender 2-point and Ruthless 4-point. The spacing between barbs on our Defender is 4" spacing. To safely contain most herds, we generally recommend 4 to 5 lines of barbed wire, spaced about 10" apart. *Red Brand Barbed Wire is available in standard low carbon 12-½ gauge wire, and 15-½ gauge high tensile wire. All of our Barbed Wire is coated with a zinc alloy for rust protection. Each style is available in Class 1, Class 3, or Commercial grade galvanization. *The primary benefit of barbed wire fence is its simplicity. The list of materials is short - just barb wire, posts, stays and staples. Red Brand's red-tipped barbs assure the highest quality steel for sharp, strong points and durable wire for lasting performance. *Style: 50 Defender *Wire Gauge: 12 ½ GA. *Barb Style: 2 Point *Spacing: 4”
