Rubber anchor chains are flexible, durable chains made from high-strength rubber materials, designed to absorb shocks and reduce noise in marine applications. Anchor chains are heavy-duty metal chains used to secure vessels to the seabed, providing stability and safety during anchoring. Both types are essential for mooring and anchoring operations in various maritime environments.

Rubber Anchor Chain:

- Size: Typically 20mm to 120mm diameter

- Grade: Not applicable (rubber lacks steel grading)

- Viscosity: N/A (non-fluid material)

- Buoyancy: Naturally buoyant due to rubber composition

- Material: High-strength synthetic rubber with embedded reinforcement (e.g., polyester or steel cables)

Steel Anchor Chain:

- Size: 10mm to 200mm diameter (common maritime sizes)

- Grade: Grade 2, Grade 3, or higher (e.g., U2, U3 per ISO 1704)

- Viscosity: N/A (solid metal)

- Buoyancy: Non-buoyant (requires markers or floats)

- Material: Forged carbon steel or alloy steel (often galvanized for corrosion resistance)
