Committed to providing our customers with durable, classic-looking alternatives to traditional wood and wood-composite products. HDPE (high density polyethylene), the plastic used to make our lumber, creates no harmful emissions—either during its production or as it is used by the consumer. Re-use of waste plastic is preferable to the creation of new plastic and the addition of old plastic to the waste stream, which is why at least 50% of the plastic we use in our manufacturing process is recycled plastic, with at least 10% coming from the post-consumer waste stream.
