Picket fences are made of polyvinyl chloride (PVC), extruded with virgin vinyl. The vinyl’s UV inhibitors and additives make it rigid, but flexible enough to resist cracking. The fence consists of vertical pickets that fasten onto horizontal rails or the pickets drop through the rails and are secured by a notching method preventing pull out. The rails insert into square posts. Our sections will never rot, warp, corrode, rust and never need painting, which reduces maintenance, costs.
