🔧 Technical Content – Solid Rubber Dock Bumper

1. Material Composition & Properties

• Base Material: 100% industrial-grade vulcanized natural rubber (NR) blended with synthetic elastomers (SBR / BR).
• Hardness (Shore A): 65 ± 5 — provides balance between rigidity & shock absorption.
• Tensile Strength: ≥ 12 MPa — resists tearing under heavy truck impacts.
• Elongation at Break: ≥ 350% — ensures flexibility without cracking.
• Compression Set Resistance: Low permanent deformation after repeated compression cycles.
• Abrasion Resistance: ≤ 200 mm³ (DIN 53516) — suitable for high-frequency dock usage.
• Temperature Resistance: -30°C to +80°C (continuous service range).
• Weatherproofing: Formulated with anti-ozone & UV stabilizers for outdoor Borneo environments.
• Chemical Resistance: Stable against oils, diesel, mild acids, and seawater exposure.

 

2. Design & Construction

• Profile Type: Solid block design — no hollow cavities → ensures maximum durability under load.
• Surface Finish: Smooth front face with slight curvature to spread impact load.
• Reinforcement: Optional internal steel plate (custom orders) for heavy-duty marine docks.
• Mounting Holes: Pre-drilled holes (typically Ø16mm to Ø20mm) for anchor bolts.
• Color: Standard black (UV-stabilized). Optional reflective striping (yellow/white) for visibility at night.

 

3. Standard Sizes (Stock Models)

• Model 330: 100mm (Thickness) × 260mm (Height) × 330mm (Length)
• Model 450: 100mm (Thickness) × 260mm (Height) × 450mm (Length)
• Model 760: 100mm (Thickness) × 200mm (Height) × 760mm (Length)
• Model 300: 100mm (Thickness) × 300mm (Height) × 300mm (Length)

📌 Custom sizing available for large marine berths, offshore rigs, or heavy-vehicle docks (up to 1200mm length).

 

4. Mechanical Performance

• Impact Absorption Capacity: Tested to withstand truck docking speeds of 2–5 km/h (standard reversing speeds).
• Load Capacity: Capable of absorbing impact forces from 10-ton to 40-ton trucks & trailers.
• Deflection under Load: ≤ 25% thickness compression at full impact.
• Rebound Resilience: 65% — ensures energy is absorbed, not transferred to structure.

 

5. Mounting & Fixing Technicals

• Recommended Fixing: Heavy-duty galvanized anchor bolts (M16–M20).
• Installation Surface: Concrete walls, steel dock frames, or marine jetty pillars.
• Bolt Depth: Minimum 75mm embedment into structural concrete.
• Installation Pattern:
  • Model 330 & 450 → 2 mounting holes.
  • Model 760 → 3 mounting holes.
  • Model 300 → 2 or 4 mounting holes (depending on orientation).
• Mounting Orientation: Horizontal or vertical depending on dock design.

 

6. Performance in Borneo Climate

• High Rainfall Tolerance: Water-resistant rubber prevents swelling.
• UV Protection: Long service life under strong tropical sunlight in Sabah & Sarawak.
• Marine Environment Suitability: Saltwater-resistant → ideal for Kota Kinabalu Port, Sandakan Jetty, Bintulu Port, Muara Harbour, Kuala Belait Oil & Gas Base.
• Temperature Fluctuations: Performs reliably in both hot midday sun and cool night conditions.

 

7. Quality & Standards Compliance

• ISO 9001: Manufactured under certified quality management system.
• DIN 53505: Hardness test compliance.
• ASTM D2000: Rubber material classification.
• RoHS & REACH Compliant: Safe for industrial environments.
• Marine Grade Option: Meets PIANC guidelines for small vessel berths and docking.

 

8. Estimated Weight (Per Unit)

• Model 330 → ~6.5 kg
• Model 450 → ~9.0 kg
• Model 760 → ~13.5 kg
• Model 300 → ~8.5 kg

(Weights vary depending on density & custom reinforcement options)

 

9. Service Life Expectancy

• Normal warehouse use: 5–8 years.
• Heavy-duty port/marine use: 3–6 years (depending on impact frequency).
• With periodic inspection: Can extend beyond 10 years with minimal degradation.

 

10. Optional Upgrades

• Embedded steel plate for extra rigidity.
• Reflective safety strips for low-light visibility.
• Extra-thick profile (150mm–200mm) for container port applications.
