Carefree solid polyethylene 2"x4" x12' deck railing, 4" x4" x9' posts, and 1/2"x21/2"x12' trim. Decided to go wire pasture fence instead, but would make about 1,000 feet of rail fence plus corral fence rails. Note: tow rope is made from polyethylene. Since it's solid plastic can be submerged in water. Since it's solid plastic there is expansion and contraction with temperature. This plastic can be worked with conventional woodworking tools. Total material weight is approx. 10,000 lbs. $6,000.00 for all/OBO
