American Structures & Design (PVC)
PVC Decking in Seattle, WA | Mill Decking
Full cellular PVC decking with no wood content whatsoever — impervious to moisture, mold, and rot in any exposure condition. The right material for below-grade applications, ground-contact builds, and any deck where moisture contact is unavoidable.
American Structures & Design produces a full cellular PVC deck board — which means there's no wood or organic filler in the core.
Where composite boards have a wood or bamboo component that can absorb moisture under extreme exposure, PVC has none. The result is a board that performs identically whether it's dry, damp, or sitting in a pool surround that gets splashed daily.
We specify this material for applications where moisture contact is unavoidable and long-term structural integrity of the surface is non-negotiable. It's also the material we recommend for any below-grade or ground-contact decking application where even the best composite would eventually show moisture stress.
Rigid, dimensionally stable, and built to last well beyond what wood or standard composite can deliver in the most demanding environments.
