DD Hollow Rubber Fender | D Shaped Dock Bumper

1. Unique DD Profile (Double-D Shape)

• Outer D-Shape: Creates a broad surface contact area, reducing point pressure on vessels and dock walls.
• Inner D-Shape Hollow Core: Allows greater elastic deformation, giving better energy absorption and shock dispersion compared to solid D fenders.
• Provides balanced compression and flexibility, ideal for both small boats and large vessels.

2. High Energy Absorption with Low Reaction Force

• Designed to absorb berthing energy efficiently, reducing risk of hull denting, paint damage, or dock cracking.
• Low reaction forces mean that both dock structures and vessels are protected simultaneously.
• Outperforms traditional Solid D Fenders by up to 30–40% more energy absorption per unit length.

3. Robust Marine-Grade Rubber Compound

• Manufactured from premium-grade natural and synthetic rubber blends with additives for:
  • UV resistance (withstands strong tropical sunlight in Sabah, Sarawak & Brunei).
  • Ozone resistance (prevents surface cracking and degradation).
  • Saltwater resistance (ideal for marine environments).
  • Abrasion resistance (endures constant vessel contact and rubbing).
• Maintains elasticity and performance even in extreme wet, humid, or hot climates.

4. Versatile Mounting & Easy Installation

• Bolt-through installation design – bolts pass directly through the hollow cavity.
• Can be mounted on:
  • Concrete dock walls
  • Steel structures (ship hulls, offshore rigs, dolphin piles)
  • Wooden jetty surfaces
• Available with pre-drilled bolt holes or supplied plain for on-site drilling.
• Installation is fast, cost-effective, and secure.

5. Flexible Size & Length Options

• Stock Sizes: 2” x 2”, 3” x 3”, 4” x 4”, 6” x 6”.
• Custom Sizes: Up to 12” x 12” for heavy-duty berthing projects.
• Continuous Extrusion Supply: Long lengths available, cut to client requirements.
• End Finishes Available:
  • Angled cut ends
  • Curved sections for hull fitment
  • End caps for aesthetic and safety finish

6. Long Service Life & Low Maintenance

• Engineered for years of continuous service in harsh environments.
• Resistant to mechanical fatigue, repeated compression, and marine growth.
• Requires minimal maintenance compared to steel bumpers or timber fenders.
• Cost-effective lifecycle solution for ports, shipyards, and industrial sites.

7. Multi-Sector Application Flexibility

• Marine Sector: Jetties, ports, tugboats, fishing harbors, supply bases, offshore rigs.
• Industrial Sector: Warehouses, truck loading docks, container terminals, logistic hubs.
• Construction Sector: Bridges, temporary works, heavy machinery protection points.

8. Safety & Performance Certified

• Designed and manufactured to international marine safety standards.
• Suitable for port authority projects, government marine works, oil & gas installations, and private dock applications.
• Tested for compression strength, elongation, hardness, and tear resistance.

9. Custom Engineering Support

• RUBASIA RUBBERTECH INDUSTRIES provides:
  • Engineering drawings & CAD support for project tendering.
  • Custom extrusion profiles for non-standard berthing applications.
  • On-site installation guidance for contractors and shipyards.
  • Bulk project supply for major infrastructure developments in Sabah, Sarawak & Brunei.
