Jan 07 2015 - Aluminum fences do not rust or rot like other fencing materials and almost never need replacing. The fastening components for these fences are either rust-proof stainless steel or fiberglass. These fences are also powder coated to maintain an attractive finish throughout their lifetime. Aluminum fencing is usually less expensive to purchase than other materials, and its lightweight qualities can significantly reduce installation labor costs. Aluminum fencing is also more easily installed on uneven or sloping ground than traditional fencing due to its adaptable design. The maintenance-free materials in an aluminum fence help to further reduce its overall cost. Aluminum fences also tend to be very simple to repair. A single damaged component can be repaired without replacing an entire section of fence. This feature makes repairs less costly than other types of fencing.
