52mm Galvanized Stud Link Anchor Chains Seafloor Engagement U1 U2 U3
Product Overview
High-performance steel forging marine mooring and anchor chain with black coating, available in both stud and studless link types. Professionally engineered for marine anchoring and mooring systems of various vessels and offshore facilities, featuring excellent structural strength, seawater corrosion resistance and load-bearing capacity. Fully compliant with international marine classification society standards and industry specifications.
Material Advantages
High-quality marine special alloy steel round bar, main grades include CM490 (U2 grade)
Steel forging process optimizes internal metal structure, eliminating internal stress
Significantly improves chain's tensile, impact and fatigue resistance
Chain Types
Stud Link Type
Internal reinforcing studs for stable structure and deformation resistance
Suitable for heavy load anchoring of large ships and offshore engineering
Nominal diameter range: 12.5mm - 120mm
Standard link size: inside length 4D, outside width 3.6D (D = nominal diameter)
Standard section length 27.5m, customizable non-standard lengths available
Studless Link Type (Open Link)
No internal studs, lighter weight, easy to match with large shackles
Avoids stud loosening faults
Nominal diameter range: 12.5mm - 70mm
Ideal for medium and small vessels, offshore permanent mooring and auxiliary anchoring
Proof load and breaking load meet U2/U3 grade international standards
Manufacturing Process
