Outdoor Building Products

Materials that Weather the Storm

There’s no room for compromise when you’re designing for the outdoors. Your materials must endure harsh climates, severe weather and extreme temperature changes.  And your market demands products that are low maintenance and high quality with a variety of appearance options.

When you work with Avient, you won’t need to compromise.

Our color and additive concentrates and selection of alloys, cellular substrate and capstock formulations are proven to withstand years of outdoor weathering without fading.  We can help you replicate the look and feel of real wood or metal in a variety of color choices including bold, dark colors that are resistant to heat build-up.

By eliminating staining or painting of wood or metal parts, we can help you reduce production costs, increase your design freedom, and improve efficiency while meeting market demand for low maintenance outdoor products.
