The Black Painted Studless Anchor Chain is a high-quality marine-grade anchor chain designed for vessels and offshore applications where reliable anchoring performance is required at a cost-effective price point. Also known as an open link anchor chain, it features links without a central stud, making it lighter and more flexible than stud link chains—easier to handle, store, and deploy in a wide range of marine environments.
Manufactured from high-strength alloy steel, the chain is available in U2 and U3 grades. U2 grade offers reliable strength for standard marine anchoring applications, while U3 grade provides higher tensile strength for more demanding offshore operations. Diameters range from 12.5mm to 50mm, covering the needs of small to medium-sized vessels, fishing boats, mooring buoys, and offshore aquaculture systems.
The black bitumen paint finish provides a protective coating that resists corrosion from seawater and atmospheric exposure. This coating offers a cost-effective alternative to hot-dip galvanizing while still delivering reliable rust protection for standard marine service conditions. The chain is manufactured using precision flash welding techniques, ensuring consistent weld quality and structural integrity across every link.
Each chain is produced in compliance with GB/T 549-2017 standards and can be supplied with classification society certification from major societies including LR, ABS, DNV, BV, CCS, NK, KR, and RINA. Available in standard 27.5-meter shot lengths or custom cut lengths upon request.
