Rubber Dock Bumpers for Sale

1. Why Every Dock Needs Rubber Bumpers ?

Every time a ship comes in, there’s a small collision waiting to happen.
Without good protection, that “soft hit” can damage both the vessel and the dock — and repairs are never cheap.

That’s why rubber dock bumpers, also called extruded rubber fenders, are so important.
They protect docks, absorb impact, and keep operations running smoothly.
At NANHAI, we build high-quality rubber dock bumpers that last, keeping ports safe and efficient all year round.

2. What Are Rubber Dock Bumpers?

Rubber dock bumpers are tough rubber profiles made by extrusion.
They absorb the energy of a ship when it comes alongside the dock, reducing impact and preventing damage.

You’ll find them everywhere —

• Commercial harbors
• Ferry terminals
• Loading platforms
• Floating docks

They’re durable, weather-resistant, and built to work even in harsh marine conditions.

3. The Three Main Types

NANHAI offers three main styles of rubber dock bumpers: DD type, DO type, and Square type with UHMW-PE panels.
Each has its own best use.

3.1 DD Type Rubber Dock Bumpers

DD bumpers have two holes inside and a flat outer surface.
They are strong, flexible, and easy to install.
Perfect for small to medium docks with light vessels.

3.2 DO Type Rubber Dock Bumpers

DO bumpers have a round front.
They’re great for tugboats or areas where ships often slide along the dock.
They absorb energy well and resist deformation.

3.3 Square Rubber Dock Bumpers with UHMW-PE Panels

This is the most advanced style.
A square rubber body supports a UHMW-PE (Ultra High Molecular Weight Polyethylene) panel on top.
The PE panel is smooth and has a super low friction surface, so ships can slide easily during berthing.
It’s the best choice for heavy-duty docks and large cargo terminals.

4. Why Choose the Square Type with UHMW-PE Panels

Square rubber dock bumpers with UHMW-PE panels are the modern solution for busy ports.

Here’s why they stand out:

• Low friction: The panel protects ship paint and reduces wear.
• High durability: UHMW-PE is 5–7 times more wear-resistant than steel.
• Easy to maintain: The panel can be replaced without removing the whole bumper.
• Long lifespan: The rubber body resists pressure, UV rays, and seawater.

These rubber dock bumpers work best at cargo berths, tug stations, and docks where ships come and go all day.

5. How to Choose the Right Rubber Dock Bumper (Main Section)

Picking the right bumper can save you thousands in the long run.
NANHAI’s engineers can help you choose the best fit for your dock project.

Here’s what to consider:

• Ship size and tonnage
• Berthing frequency
• Dock structure (concrete or steel)
• Environmental factors like tides, temperature, and saltwater

For large docks and heavy traffic, the square type with UHMW-PE panels is your best option.
It combines strong impact absorption and smooth surface contact — perfect for high-pressure operations.

EUDR-Certified and Sustainable

At NANHAI, we care about the environment as much as performance.
Our rubber dock bumpers are made with materials that meet EUDR (European Deforestation Regulation) standards.
That means our rubber comes from traceable, legal, and sustainable sources.
Choosing NANHAI means choosing both quality and responsibility — for your dock and for the planet.

6. Installation and Maintenance

Installation is simple:

• Mount the bumper tightly against the dock surface.
• Use galvanized or stainless-steel bolts for long-term strength.
• Leave a small gap for the PE panel to expand or shrink with temperature changes.

Maintenance is easy too.

• Check for cracks or loose bolts a few times a year.
• Replace the PE panel if it wears down more than 30%.
• Wash off salt and dirt to prevent corrosion.

With proper care, your NANHAI bumper can last well over a decade.

7. Quality and Material Performance

Rubber body:

• Hardness: 70 ± 5 Shore A
• Tensile strength: ≥ 15 MPa
• Tear strength: ≥ 60 kN/m
• UV and ozone resistant

UHMW-PE panel:

• Friction coefficient: 0.12–0.2
• Wear resistance: 5–7x better than steel
• Resistant to saltwater, sunlight, and impact

Every bumper from NANHAI is tested before delivery.
We check dimensions, hardness, and bonding quality to make sure each product meets international port standards.

8. Cost and Long-Term Value

The square type with UHMW-PE panels costs a bit more at first,
but it lasts longer and needs less maintenance — saving you money over time.
NANHAI also offers custom sizes and drilling patterns to match your dock design, reducing total installation costs.

9. FAQs

Q1: What’s the difference between DD, DO, and Square types?
DD and DO are simpler and great for light docks.
Square type with UHMW-PE is stronger and ideal for heavy use.

Q2: Can I replace the PE panel only?
Yes. It’s fixed with bolts, so you can change it easily.

Q3: How long do rubber dock bumpers last?
Usually 10–15 years, depending on how often they’re used.

Q4: Does NANHAI offer custom options?
Absolutely. We can adjust the size, hole pattern, and panel thickness.

Q5: Are NANHAI bumpers environmentally friendly?
Yes. All our products meet the EUDR sustainability requirements.

10. Conclusion and Call to Action
