Photographer: Tom Crane Made of 300, 10-foot steel blades set upright 8 inches apart, the award winning Cor-Ten Cattails Sculptural fence was designed for a home in Berwyn, Pennsylvania as a yard sculpture that also keeps deer out. Made of COR-TEN, a steel alloy that eliminates the need for painting and maintains a rich, dark rust color without corroding, the fence stanchions were cut with a plasma cutter from sheets of the alloy. Each blade stands 8 feet above grade, set in concrete 3 feet below, weighs 80-90 pounds and is 5/8 inch thick. The profile of the blades is an irregular trapezoid with no horizontal connections or supports. Only the gate has two horizontal bars, and each leaf weighs 1200 pounds.
