Commercial or Industrial ornamental fencing comes in steel or aluminum. Both the steel and the aluminum are tubular in their construction and are still a fraction of the cost of wrought iron. The biggest difference between residential ornamental fencing and commercial ornamental fencing is the picket size. Residential pickets are normally 5/8” square and the commercial picket is 3/4″ or 1″ square. Common heights for commercial ornamental fencing are 5’ 6’ 7’ and 8’. Other heights are available as a special order.
