Dock Floats & Dock Flotation

DPI dock floats are heavy‑duty, rotationally molded polyethylene floatation units filled with EPS foam, designed for residential and commercial floating docks. DPI (Diversified Plastics, Inc.) manufactures plastic dock floats engineered for durability and long‑term buoyancy. They use a one‑piece rotationally molded shell made from virgin polyethylene with UV inhibitors, preventing seam failures and resisting damage from sun, saltwater, freshwater, debris, oil, gas, and marine organisms. Inside each float is expanded polystyrene (EPS) foam, providing stable buoyancy and preventing water intrusion even if the shell is punctured. Key Features Flat‑top design with molded‑in mounting slots for easy attachment to wood, steel, or aluminum dock frames. .150" nominal wall thickness for strength and impact resistance. EPS foam‑filled interior for reliable flotation. Made in the USA and suitable for both new construction and retrofits
