Marine Chains
STUD LINK ANCHOR CHAIN
A stud link anchor chain made from hot-rolled anchor steel with CM490 or CM690 grade, available in sizes from 13mm to 152mm diameter. The chain features a stud welded across the link body for increased strength and resistance to wear. It is supplied in hot dip galvanized or black painted finish and can be cut to length per order. Standard grades include U2 and U3, with options for stainless steel 316 and 316L. The chain is designed for marine and offshore applications where high tensile strength and durability are

Application Scenarios
Where Stud Link Anchor Chain Is Used
- Offshore platform mooring systems requiring high-strength, corrosion-resistant chain with stud reinforcement
- Large commercial vessel anchor systems where chain elongation and wear must be minimized
- Marine construction and dredging operations using heavy-duty mooring and towing chains
- Harbor and port infrastructure with fixed mooring bollards exposed to saltwater and heavy loads
- Oil and gas rig mooring lines where chain integrity under dynamic loads is critical
- Heavy-duty towing operations for submerged structures and floating equipment
- Custom marine installations where chain length must be precisely matched to anchor point spacing
Who It Is For
Buyers This Product Is Built For
- Marine equipment suppliers specifying anchor chains for commercial and offshore vessels
- Shipyards and marine contractors installing mooring and anchoring systems
- Offshore platform operators maintaining mooring chain integrity under cyclic loading
- Port authorities managing fixed mooring systems for large vessels and floating docks

Problems It Solves
Problems This Product Removes
- Chain elongation and link deformation under repeated dynamic loads due to lack of stud reinforcement
- Corrosion damage in saltwater environments from untreated or poorly coated chain surfaces
- Mismatch between chain length and anchor point spacing leading to excess slack or tension
- Inconsistent strength across chain links due to non-uniform material or welding quality
- Need to source multiple chain types from different suppliers for a single mooring system
- Lack of traceability in chain grade and material certification for safety-critical marine applications
- Inadequate resistance to wear at high-load contact points in mooring and towing systems

How It Compares With The Alternatives
An honest read on where this pattern wins and where another one would serve you better.
| Alternative | Honest Trade Off |
|---|---|
| Non-stud link chain | The stud link design resists elongation and wear under dynamic loads but adds weight and cost |
| Riveted link chain | Stud link chains have higher strength and better fatigue resistance but require welding and are not suitable for all riveting applications |
| Forged chain | Stud link chains are more cost-effective and easier to produce in long lengths but may not match the impact resistance of forged chains |
| Plain carbon steel chain | CM490 and CM690 grades offer higher tensile strength and better performance under marine loads |
Use Guide
How To Use And Inspect Stud Link Anchor Chain
- Verify the stamped grade and working load limit match the application requirements
- Inspect the stud weld and link surface for cracks or deformation before use
- Ensure the chain is properly galvanized or painted to resist corrosion in marine environments
- Cut chain to length only after confirming the final installation dimensions
- Avoid sharp bends or kinks that can damage the stud weld and reduce strength
- Do not reuse chain that has been exposed to overloading or impact damage
- Store chain in a dry, covered area to prevent surface corrosion during storage
