Adding chain to an anchor involves connecting anchor chains to the anchor to provide weight and stability. The chain helps keep the anchor lying flat on the seabed for better holding power. Properly sized and connected chains ensure secure anchoring for vessels.

Grade: Grade 2, Grade 3, U1, U2, U3, R3, R3S, R4, R4S, R5

Viscosity: Not applicable (solid metal construction)

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

Material: High-strength carbon steel or alloy steel, often galvanized or coated for corrosion resistance

Breaking Load: Varies by size and grade (e.g., 12.5 mm Grade 2 ~ 6.5 tons, 76 mm R4 ~ 3,500 tons)

Proof Load: Typically 50% of breaking load

Length: Standard stud link chain lengths of 27.5 meters (90 ft) per shot

Stud Link: Common design for anchor chains, providing strength and stability

Certification: Class-approved (e.g., ABS, DNV, LR, BV)

Corrosion Protection: Hot-dip galvanizing, zinc-aluminum coating, or other anti-corrosion treatments
