Abstract: Concrete Picket Fence Replacement is an innovative upgrade to designer and durable fencing, comprising the strength of concrete, steel, and stone to create a series of interlocking panels, capable of resisting the destructive forces of wind, water, fire, and deterioration from insects and animals. In preferred embodiments, a strong matrix of Concrete Picket Fence boards are adhered vertically along a horizontal metal pipe by welding metal points of contact, creating a solid fence panel anchored to the ground by metal fence posts secured by concrete. To date, concrete and steel have not been combined in such fashion. The return will be a conservation of trees and lower costs due to loss, theft, and replacement cost.
