Steel hex web dog outdoor enclosures combine a professional and nearly invisible look with the benefits of chew-resistant steel. Our invisible pet fencing is made of 20 gauge galvanized steel that will resist all attempts by animals to chew through to the other side, potentially harming your pet. The 5 foot dog fence is PVC coated to protect the steel from wear and tear that can be caused by the elements. The 1 inch mesh grid design of steel hex dog fence is also stronger than traditional square mesh designs--all of these features combined gives you a fence that will remain effective for 20-30 years. The black coating of this fence, aside from protecting it, also creates a fence that will be unnoticeable from as close as 20 feet.
