Rubber Blocking Buoys

Rubber Blocking Buoys from Hongruntong Marine are purpose-built heavy-duty solutions for blocking passages, protecting harbors, and controlling navigation areas. Designed for commercial and industrial marine use, our large rubber blocks and huge black rubber buoys combine rugged materials, reinforced construction and flexible installation options to deliver reliable, long-lasting passage blocking and containment.

Rubber Blocking Buoys are engineered floatation and blocking devices used to close channels, protect work zones, and create temporary or semi-permanent barriers at ports, marinas and offshore sites. Hongruntong Marine manufactures a range of sizes and configurations — solid rubber, foam-filled or hollow with reinforced shell — so you can choose the best balance of buoyancy, weight and durability for your project.

Key Features

• Durable Rubber Construction — High-grade rubber compound (SBR/NR blend) resists saltwater, UV, oil and abrasion for extended service life.

• Reinforced Core — Multi-layer textile cord or embedded reinforcement for impact resistance and reduced deformation.

• Multiple Filling Options — Solid, foam-filled or hollow (with internal chamber) to meet buoyancy and handling preferences.

• Heavy Duty Attachment Points — Built-in stainless steel or galvanised lifting eyes and mooring bales for safe towing and anchoring.

• Rapid Deployment — Modular design and manageable lifting points enable quick installation with standard marine equipment.

• Low Maintenance — Simple cleaning and inspection; long replacement intervals reduce operating costs.

• Customizable — Sizes, eye position, hardware, and marking/branding available to project specifications.

Typical Applications

• Port and marina passage closure

• Emergency containment and spill response zones

• Construction site isolation (dredging, pile driving, repair works)

• Temporary channel re-routing and navigation control

• Harbor protection during special events or military drills

• Offshore platform work area demarcation

Competitive Advantages

• Commercial Warranty & After-sales — Standard warranty terms with optional extended support packages and spare parts.

Technical Specifications

Note: the following are typical examples. Exact values depend on selected model and custom requirements. Contact Hongruntong Marine for precise calculations and certified drawings.

Materials & construction

• Rubber compound: SBR/NR blend or other marine-grade elastomers (oil & UV resistant)

• Reinforcement: multi-layer textile cords and/or internal steel/galvanized braces (optional)

• Hardware: stainless steel AISI 316 or hot-dip galvanized lifting eyes and shackles (as requested)

• Color: standard black (high-visibility markings or colored panels available)

Environmental & performance

• Operating temperature range: approx. −45°C to +80°C (depends on compound)

• Resistance: saltwater, oils, sunlight, abrasion

• Service life: typically 8–15 years depending on service conditions and maintenance

• Certification: manufacturing and testing to client-specified standards; class approvals (DNV/ABS/CCS) available on request

Custom options

• Foam filling density and buoyancy tuning

• Interlocking edges / connector hardware for continuous block lines

• High-visibility reflective panels, logos and numbering

• Anti-abrasion skid pads or sacrificial covers

Installation & Maintenance (Short Guide)

• Installation: Tow or lift the buoys into position using rated lifting points; anchor per project mooring plan. For continuous barriers, connect modular blocks with supplied shackles or link chains.

• Inspection: Visual check for cuts, deformation, hardware integrity every 3–6 months (or after major events).

• Maintenance: Clean with fresh water and mild detergent; replace worn shackles and inspect reinforcement points. Repair kits and in-field vulcanization services are available.

• Storage: Store away from direct sunlight and hydrocarbons when not in service; avoid contact with sharp objects.

FAQ — Frequently Asked Questions

Q: What is the difference between foam-filled and solid Rubber Blocking Buoys?
A: Foam-filled buoys offer positive buoyancy even if the outer skin is punctured; solid rubber blocks are heavier and more impact-resistant but may offer less buoyancy per volume. Choice depends on handling equipment and buoyancy requirements.

Q: Can you deliver custom sizes or bespoke designs?
A: Yes. Hongruntong Marine specializes in custom designs — we provide drawings, buoyancy/load calculations and prototype options.

Q: How long does delivery take?
A: Lead time depends on size, quantity and customization. Typical production lead time for standard models is quoted per inquiry — contact our sales team for an exact schedule.

Q: What hardware is provided?
A: Standard supply includes stainless or galvanized lifting eyes and mooring points. Heavy-duty shackles, chain and connectors are available as options.

Q: Are these buoys suitable for permanent use?
A: Rubber Blocking Buoys are designed for long service life, but periodic inspection and maintenance are recommended. For permanent installations, we advise specifying materials and hardware for long-term marine exposure.

Q: What warranty do you offer?
A: Standard commercial warranty terms apply; extended warranties and service agreements are available based on project scope.

Q: Can you meet classification society requirements or provide test reports?
A: Yes — Hongruntong Marine can produce test reports, material certificates and cooperate with classification societies (DNV, ABS, CCS) on request.
