A Studless Anchor Chain is a heavy-duty marine chain used to secure ships, offshore platforms, and floating units, manufactured without the central stud that is present in stud link chains. Our factory makes high-quality Studless Anchor Chains for both commercial and offshore use. We are one of the best anchor chain manufacturers and suppliers in China. The stud free design makes the chain lighter,easier to use and more flexible, while still provides the strength needed for anchoring and mooring.
The Studless Anchor Chain comes in sizes from 6mm to 90mm, making it suitable for a wide range of vessels and offshore structures. It’s much lighter than traditional stud link chains, which allows easier handling, storage, and installation, while still maintaining great fatigue resistance in harsh marine environments. The flexible link design reduces the risk of getting stuck and ensures smoother operation under cyclic loads.
The Studless Anchor Chain’s weight reduction and simplicity of use are its biggest advantages. It’s more cost-effective for smaller ships or platforms, requires less storage space, and is economical without compromising safety, shipowners and offshore operators frequently favor this type. Studless chains are more efficient during anchoring operations, they tend to wind on windlasses and chain lockers more smoothly.
Yes. Each Studless Anchor Chain that we manufacture is put through a rigorous testing process. To guarantee adherence to global standards and classification society requirements, our factory performs proof load tests, breaking load tests, and dimensional inspections. With certificates from ABS, DNV, LR, BV, NK, KR, CCS, RINA, and RS, we are confident that each chain shipped from our factory is solid, safe, and ready for immediate use.

When operators want lighter, more flexible chains without compromising dependability, then the Studless Anchor Chain is the perfect choice. They are widely used in coastal vessels, small-to-medium ships, fishing boats, barges, offshore support units, and floating marine structures. Studless chains are also utilized in auxiliary or temporary mooring applications in offshore projects where high strength is needed but lower chain weight offers operational benefits.
