Marine Hardware Dock Floats & Pontoon Cubes — Manufacturer & OEM Supplier
Everwin Sports manufactures the flotation under floating docks, marinas, swim platforms, and work pontoons — rotomolded HDPE dock floats, modular floating-dock cubes, and under-dock drum and billet floats. Shells are one-piece, seamless polyethylene, foam-filled with closed-cell EVA or polyurethane so a punctured float stays buoyant, and UV-stabilized against years of sun and waterline exposure. Drop-in floats carry molded-in mounting flanges and through-bolt bosses, while interlocking cubes snap together with connection pins to build dock, platform, and jet-ski port layouts to any plan. Buoyancy ratings span light residential docks through commercial marina and aquaculture walkway loads.
Available factory-direct from our Weihai, China facility for wholesale, private-label and custom OEM production — alternate materials, sizes and branding, typically from 500 units, for buyers across major export markets.

Common questions
What float types do you make, and how is buoyancy sized?
We supply drop-in under-dock floats, modular interlocking pontoon cubes, and billet floats, in a range of footprints and buoyancy ratings. Buoyancy is sized to the dead load of the structure plus the live load you expect from people, equipment, or moored craft, with reserve so the deck rides high and dry. Send your dock dimensions and intended load and we will calculate the float count.
How are the floats built, and what makes them last?
Shells are rotomolded in one seamless piece of UV-stabilized HDPE and filled with closed-cell EVA or polyurethane foam, so even a punctured float keeps its buoyancy rather than swamping. There are no seams to split and no internal air space to leak. The polyethylene resists impact, marine growth, and years of waterline sun.
Should I choose drop-in floats or modular cubes?
Drop-in floats bolt under a timber or aluminum dock frame and suit fixed, engineered structures, while interlocking cubes pin together without a frame to build docks, swim platforms, and jet-ski ports that can be reconfigured or extended. Many projects mix both. Tell us whether you are framing a dock or assembling a modular platform and we will recommend the float system.
Can floats and cubes be customized or produced under OEM or private label?
Yes — float size, buoyancy, flange and boss layout, cube connection pattern, and color are all configurable, and we run OEM and private-label programs with molded branding. First runs include sampling. Provide your dock drawings or a reference unit and we will quote and sample to it.
What is the minimum order quantity?
Standard floats and cubes ship by the pallet and consolidate toward container volume, though they are bulky, so loading is planned to fill the container efficiently. Custom or private-label runs typically start around 500 units. Large dock projects are quoted per project given size and freight.
What is the production lead time?
Standard floats and cubes run about 30–45 days after deposit. A first-time custom or branded run takes roughly 45–60 days including sampling, with repeats back to 30–45 days. Molding, foam filling, and assembly are scheduled inside that cycle.
