摘要： A fence system having treated wooden posts set in concrete at spaced-apart locations. Galvanized metal stringers extend between the posts and engage the post at a mounting surface. The mounting surface defines a plurality of vertically-elongate slots through which fasteners extend. Pickets are secured to the stringers and are vertically oriented. The stringers are secured by fasteners such as screws. Preferably the stringers are formed from HDPE and expansion and contraction of the pickets is accommodated by the slots in the mounting faces of the stringers. The pickets are formed by grinding waste plastic and adding UV inhibitors and color if desired. The ground plastic material is extruded under heat and pressure and the desired surface treatment applied to simulate the appearance of natural wood fencing. The surface-treated extrusion is cut to the desired length to form individual pickets.
