Hi Tensile Wire & Cord

Hi-tensile wire is the backbone of permanent agricultural fence — solid galvanized steel drawn to deliver maximum strength per pound. Powerflex stocks ASTM A641 Class 3 hi-tensile wire in 12.5 gauge at both 170,000 PSI and 200,000 PSI grades, plus our Livestock Guardian woven wire in 7-35-18 fixed-knot configuration. All of it builds fence that lasts decades, not seasons.

Speccing your fence? See our hi-tensile wire technical reference — gauge sizing tables, tensile-strength comparison, Class 3 vs Galfan galvanization, post spacing, tensioning specs, splicing methods, and brace assemblies. Sourced from ASTM A641 and USDA NRCS CPS 382.
