Our ZA High Strength Sheep and Goat Fences have 4" x 4" openings which are made from high strength steel. Strong knots help keep sheep and goats confined. Our ZA High Strength Sheep and Goat Fencing have a technically designed coating exclusively made by Bekaert. Bekaert ZA (95% Zinc, 5% Aluminum) coating maximizes fence life and value. Adding 5% Aluminum results in a coating that lasts three times longer than Class 1 at a better value.
