Calibrated Anchor Chains are precision-engineered chains with consistent link dimensions for accurate load measurement. Anchor Chains are heavy-duty chains used to secure vessels by connecting the anchor to the ship. Both are critical for maritime safety and stability.

Size: 12.5 mm to 162 mm diameter

Grade: Grade 2, Grade 3, Grade 4, and higher grades like R3, R3S, R4, R4S, R5

Viscosity: Not applicable (anchor chains are solid metal components)

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

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

Breaking Load: Varies by size and grade (e.g., 12.5 mm Grade 2: ~32 kN, 162 mm Grade R4: ~18,000 kN)

Proof Load: Typically 50-70% of breaking load

Length: Standard shots of 27.5 meters (90 feet) with detachable links

Surface Treatment: Galvanized, painted, or bare steel

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

Weight: Varies by size (e.g., 12.5 mm: ~2.2 kg/m, 162 mm: ~300 kg/m)

End Fittings: Swivels, shackles, or detachable links for connection
