Double wire fence, also called welded double horizontal wire fence or twin wire fence, is formed by a double horizontal wire, a vertical wire and that is the reason why this kind of wire fence is more stable than common welded mesh fences. It is made from mild steel, carbon steel or stainless steel and the surface treatment is coated by hot dipped galvanization or polyester powder. Because of the stable structure, beauty and landscaping, double wire fences with square or peach posts are popular in parks, industrial sites or residences all around the world.
