HDPE Marine Grade Sheet is a high-density polyethylene board specially formulated for harsh marine and outdoor environments. With enhanced UV resistance, excellent impact strength and outstanding resistance to saltwater and moisture, it is widely used for boat and ship components, docks, pier fenders, floating structures and coastal engineering projects where long-term durability and low maintenance are critical.
- Designed for marine environments: Resistant to saltwater, moisture and many marine chemicals, suitable for long-term use in ports, marinas and coastal areas.
- UV-stabilized and weather-resistant: Formulated with UV stabilizers to reduce fading, embrittlement and surface degradation under strong sunlight and outdoor exposure.
- High impact toughness: Withstands repeated impact from waves, boats and equipment, making it ideal for fenders, bumpers and structural panels.
- Low water absorption and non-rot: Does not absorb water, will not rot, swell or delaminate like wood or some composite materials.
- Easy to machine and install: Can be cut, drilled, routed and fabricated with standard tools, allowing customized shapes and assemblies according to drawings.
