Patriot Docks Poly Decking Panels deliver a premium dock surface built for strength, safety, and longevity. Engineered to handle the toughest waterfront conditions, these panels are designed to stay cool, dry, and secure season after season. Each 4' x 4' panel features a thru-flow surface, allowing water and air to pass through-reducing heat buildup, improving drainage, and minimizing wind uplift in rough weather. Unlike standard plastic dock boards, Patriot Poly Panels include an aluminum-reinforced core for superior rigidity and support. This added strength prevents sagging, flexing, and premature wear, ensuring your dock remains solid and dependable for years to come. Available in Gray or Tan, these panels also feature an anti-slip ribbed texture for safer footing and are made from UV-resistant polymer that resists fading and sun damage.
