Anchor Chain Marking System: Typically made of high-visibility plastic or steel tags, marked with chain length indicators (e.g., red for 25m, white for 50m). Size varies by chain diameter, usually 50-150mm in length. Material: UV-resistant polymers or corrosion-resistant metals.
Anchor Chains: Common sizes range from 12mm to 150mm in diameter. Grades include Grade 2, Grade 3, and higher (e.g., U3, R4, R5). Material: High-tensile steel with galvanized or painted coatings. Viscosity: Not applicable (solid metal). Buoyancy: Negative (sinks in water due to high density).
