Continuously Extruded Structural-Grade Plastic Lumber

Tangent’s Structural products are designed to be customized to meet individual strength and load bearing requirements for a variety of product and component needs. Tangent’s Structural Continuously Extruded materials can be formulated to project requirements, with various loading levels of reinforcing fibers and other proprietary ingredients to meet your project specifications.

This material is ideal for light- to medium-duty commercial or industrial applications. For the most demanding structural applications, we add continuous and full-length fiberglass rebar within the cross section to reach the highest strength possible to meet your component, product or overall project need.

Designed to satisfy a range of structural requirements, our Structural CE products are stronger, stiffer and have a lower coefficient of thermal expansion and contraction than our other recycled plastic lumber products.

Available in any transportable length, our Structural CE products match function and aesthetics by utilizing a co-extruded skin that allow for a beautiful finish and color flexibility. This external skin or “cap” encases the inside core and is comprised of the highest quality resins, pigments and UV-resistant additives; creating a durable, superior external finish with no compromises of beauty.
