Our poly lumber 2" x 4" boards are made from high-density polyethylene (HDPE) plastic — built to withstand the elements and last for decades without rotting, splintering, or fading. Available in 26 colors and sold in 3-packs, 6-packs, or full pallets for larger projects. Allow up to 10 business days to ship.

Note: "2×4" is a nominal dimension. Actual board size is 1-1/2" × 3-1/2".
