Marine-grade HDPE sheets are designed for harsh environments where saltwater exposure, UV sunlight and wet surfaces are daily conditions. They are widely used in aquaculture and marine projects for walkways, panels, fenders, covers and corrosion-resistant components.
- Saltwater & corrosion resistance – an alternative to metal in many marine structures.
- UV-stabilized options for long-term outdoor exposure on docks and farms.
- Low water absorption helps maintain stable dimensions in wet use.
- Anti-slip surface options to improve safety on walkways.
- Custom fabrication – cut-to-size, drilled holes, textured surfaces.

FAQ
What makes HDPE “marine-grade”?
Typically it refers to HDPE selected for outdoor UV exposure and marine use conditions. Tell us your environment and we’ll recommend a suitable grade.
Do you provide UV-stabilized sheets?
Yes. UV-stabilized/black UV grade is available for long-term outdoor exposure.
Can you provide anti-slip surface?
Yes. Textured and anti-slip surfaces can be produced for walkway safety.
What thickness is recommended for walkways?
It depends on span, support structure and load. Share your design and we’ll recommend thickness.
Will HDPE swell in water?
HDPE has very low water absorption, so dimensional change is minimal in wet environments.
Can you cut and drill panels for installation?
Yes. We offer cut-to-size, drilling and CNC machining based on drawings.
What colors are commonly used in marine projects?
Black and blue are common; custom colors can be supplied by quantity.
How do you pack for export?
Protective film plus pallet/crate packing suitable for export shipping.
Can you supply to contractors and distributors?
Yes. We support stable supply, OEM packing and project deliveries.
What information do you need for a quote?
Panel size, thickness, surface requirement, quantity, destination and environment details.
