Floating Dock Anchor Chain Supplier - Anchor Chains

Floating dock anchor chains are heavy-duty chains used to secure floating docks to the seabed or lakebed. These chains provide stability and prevent the dock from drifting due to waves or currents. They are typically made of galvanized steel or other corrosion-resistant materials for durability in water environments.

Size: 1.5 inches to 5 inches (38 mm to 127 mm) in diameter

Grade: Grade 2, Grade 3, or higher (ASTM A986, A987 standards)

Viscosity: Not applicable (chains do not have viscosity properties)

Buoyancy: Negative (submerged due to weight, unless fitted with buoyancy aids)

Material: High-strength carbon steel, galvanized or ungalvanized

Breaking Load: Varies by size and grade (e.g., 1.5-inch chain ~150 kN, 5-inch chain ~2,500 kN)

Proof Load: Typically 50-60% of breaking load

Corrosion Resistance: Enhanced by galvanization or special coatings

Link Type: Studlink or studless (common for marine applications)

Weight: 10-200 kg/m depending on size and material

Elongation: Minimal under load (designed for high rigidity)

Standards Compliance: ABS, DNV, ISO, or other marine classification societies
