Dock anchor chains are heavy-duty chains used to secure vessels to docks or moorings. Anchor chains provide strength and durability to hold ships in place against tides and winds. They are typically made of high-grade steel to withstand harsh marine conditions.

Size: 12mm to 200mm diameter

Grade: Grade 2, Grade 3, ORQ, and High-Tensile (U3, R3, R4, R5)

Viscosity: Not applicable (chains are solid metal)

Buoyancy: Negative (sinks in water due to high-density material)

Material: Carbon steel, alloy steel, or stainless steel

Finish: Hot-dip galvanized, self-colored, or painted

Breaking Load: Varies by size and grade (e.g., 12mm Grade 3: ~47 kN, 100mm R4: ~12,500 kN)

Proof Load: Typically 50-70% of breaking load

Length: Standard 27.5m shots, customizable lengths

Weight: Depends on size (e.g., 12mm: ~2.2 kg/m, 100mm: ~150 kg/m)

Certification: ABS, DNV, LR, BV, or other class society approvals
