Design flexibility

Curved products are just one more option to give your TimberTech composite deck a custom, finishing touch. Imagine the design possibilities when you add curved rail to your deck. RadianceRail and Ornamental Rail systems can be bent to your specifications, so you can create an outdoor living space that is not only low maintenance, but also beautiful and unique. BuilderBoard and most TimberTech planks can also be curved.
