Product Description

Product Overview

This seamless thick HDPE rotomolded float is a single-piece rotational molding floating pontoon manufactured by our professional rotomolding facility. The entire float body utilizes thickened seamless HDPE rotomolding technology with a closed hollow thick-wall structure that eliminates connecting buckles and splicing joints. Made from modified anti-corrosion, anti-UV HDPE raw material, it delivers stable waterproof and buoyancy performance suitable for long-term use in seawater, lake water, and river water applications.

Ideal for yacht buffer floats, water isolation barriers, landscape floating decorations, and equipment floating support. We provide comprehensive OEM & ODM customization services including outer shell color options for marina engineering contractors, scenic water project suppliers, and water facility construction merchants.

Key Features & Benefits

One-Piece Seamless Construction: Integrally rotomolded without splicing seams or welding gaps. Thickened double-layer hollow wall structure provides powerful buoyancy while eliminating water seepage and sinking risks. All edges feature full circular arc transitions without sharp burrs to prevent injuries and rope damage.
Impact Resistant & Anti-Corrosion Material: Industrial thickened HDPE mixed with high-efficiency UV stabilizers and anti-corrosion agents, resistant to long-term seawater salt erosion, sun fading, and collision damage from boats. Will not crack, embrittle, or deform after years of water surface use, with no rust issues compared to metal floating pontoons.
Closed Hollow Integrated Design: Integral closed hollow structure forms independent floating units with balanced buoyancy and uniform load-bearing capacity. Can be fixed by ropes or steel frames according to project requirements for water buffer, isolation, and floating support applications.
Superior Buoyancy & Load Capacity: Hollow closed cavity design ensures complete waterproofing and permanent buoyancy. Single float supports heavy load bearing, evenly disperses pressure when equipment or counterweights are placed on top, effectively preventing tilt and rollover.
Multi-Color Customization: Available in blue, black, yellow, and other solid colors. Customers can select matching float colors according to yacht marinas, scenic spots, and water park project requirements.

Great value for money. Compared with other brands, SUNMORE's molds have longer service life and more reasonable prices. We plan to expand our order quantity next time.
