Marking an anchor chain involves painting or attaching colored links to indicate chain length for safe anchoring. Anchor chains are heavy-duty chains connecting a vessel to its anchor, providing strength and weight. Proper marking ensures accurate deployment and retrieval of the anchor during maritime operations.

Size: 12.5 mm to 152 mm (diameter)

Grade: Grade 2, Grade 3, U1, U2, U3, K3, K4 (common grades)

Viscosity: Not applicable (chains are solid metal)

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

Material: High-tensile steel, alloy steel, or galvanized steel

Marking: Hot-dip galvanized, painted, or stamped with grade and size

Breaking Load: Varies by grade and size (e.g., Grade U3 has higher strength than Grade 2)

Length per Shackle: Typically 27.5 meters (15 fathoms)

Corrosion Resistance: Enhanced by galvanization or special coatings

Weight per Meter: Depends on size and material (e.g., 13.5 kg/m for 20mm chain)
