Manufactured from high-grade CM490 steel bar, this anchor chain delivers exceptional strength, durability, and long-term reliability, ensuring your boat or ship remains safely anchored in various marine conditions.
As a trusted U2 grade mooring chain, it is specifically designed to meet the rigorous demands of both professional seafarers and leisure boat owners. Whether you are outfitting a fishing boat, a luxury yacht, or a small commercial workboat, our 34mm anchor chain provides the perfect balance of high tensile strength and manageable weight, making it a versatile choice for dependable anchoring and mooring operations.
To suit different environmental conditions and aesthetic preferences, we offer this chain in two durable finish options:
-
Black Painted Finish: A traditional, cost-effective coating that provides excellent protection during storage and normal use.
-
Hot-Dip Galvanized Finish: For superior, long-lasting corrosion resistance in harsh saltwater environments, our hot-dip galvanized anchor chain offers a rugged, silver-grey protective layer that stands up to the elements.
Every shackle (27.5 meters) of our U2 stud link chain is manufactured to precise specifications (diameter tolerance of ±1%) and is available with full certification from all major classification societies, guaranteeing compliance with international safety and quality standards.

Frequently Asked Questions (FAQs)
Q1: What is the difference between U2 and U3 grade anchor chain?
A: The grade indicates the strength of the steel. U2 grade anchor chain (like our 34mm chain) is made from CM490 steel and is considered a “standard” strength grade, ideal for a wide variety of commercial and recreational vessels. U3 grade is made from higher tensile steel (like CM690) and is approximately 30% stronger. U3 is typically specified for larger commercial vessels, offshore platforms, or operations in extremely harsh conditions where maximum holding power is critical.
Q2: Should I choose black painted or hot-dip galvanized finish for my chain?
A: The choice depends on your operating environment. Black painted chain offers good basic protection and is a cost-effective solution for vessels operating in less corrosive environments or where the chain is not permanently submerged. However, for superior long-term corrosion resistance, especially in saltwater marine environments, we strongly recommend the hot-dip galvanized finish. The galvanizing process coats the steel in a layer of zinc, providing sacrificial protection that significantly extends the chain’s lifespan.
Q3: What does “stud link” mean, and why is it important?
A: A stud link anchor chain features a solid bar (the “stud”) across the center of each link. This stud serves two vital purposes: it prevents the link from kinking or deforming under extreme load, and it helps the chain handle more smoothly in the hawsepipe and windlass gypsy. This design is the industry standard for reliable anchoring and mooring on vessels of all sizes.
Q4: What certifications are available for this 34mm chain?
A: Our U2 mooring chain can be supplied with certification from all major international classification societies, including ABS, BV, CCS, DNV·GL, KR, LR, NK, RINA, and RS. This certification provides official verification that the chain has been manufactured and tested according to the strict rules of that society, which is often a mandatory requirement for insured commercial vessels.
Q5: What is the proof load for the 34mm chain, and how is it tested?
A: The proof load for our 34mm U2 chain is 468 kN. During manufacturing, sample links are subjected to this force in a testing machine. The chain must withstand this load without any permanent deformation or failure. This test verifies the integrity of the CM490 steel and the manufacturing process, ensuring that the chain you receive is safe and reliable for its intended working load limit.
Q6: Is this chain suitable for use on a large yacht or a small fishing boat?
A: Yes, the 34mm diameter is a versatile size suitable for a range of medium to large vessels. However, selecting the correct chain diameter is critical for safety. It depends entirely on the vessel’s displacement and the size of your windlass. A 34mm anchor chain is typically used on larger yachts, commercial fishing vessels, tugs, and workboats. Always consult your vessel’s specifications or a naval architect to confirm the correct chain size for your specific application.
