The maritime and offshore industries rely heavily on high-quality studless chains for anchoring and mooring applications. In the UK, numerous top-tier Studless Chain Manufacturers and Suppliers provide robust, certified chains tailored for commercial shipping, offshore platforms, and marine civil projects. This article explores the leading players in the UK studless chain market, their products, certifications, manufacturing processes, and OEM services, while also detailing key features and applications of studless chains.
Studless chains, also known as open link anchor chains or calibrated chains, are a critical component in marine anchoring and mooring systems. Unlike stud link chains, they feature links without a reinforcing stud bar inside each link, offering greater flexibility and reduced weight. This design makes studless chains ideal for applications where chain bending frequently occurs, such as offshore mooring.
Typically made from high-tensile steel grades like Grade R3, R3S, and R4, studless chains assure durability and strength under harsh marine conditions. They come in diameters from 16mm to 152mm and abide by international classification standards including ABS, DNV, Lloyd's Register, BV, and CCS, ensuring reliable performance in demanding environments.
Studless chains undergo a stringent manufacturing process to ensure safety, strength, and durability:
- Material Selection: Marine-grade alloyed or carbon steel is chosen based on application requirements, with grades that meet international standards such as ISO 1704 and IACS W18 & W22.
- Forging: Each link is forged from high-quality steel billets. The forging process imparts strength and shape to the links, ensuring resistance to tensile forces and fatigue.
- Welding: The chain links are welded to form continuous chains of designed lengths, typically produced in shots of about 25 meters, which are then connected with detachable links.
- Heat Treatment: Heat treatment processes enhance the mechanical properties by improving toughness and fatigue resistance.
- Calibration: Each link is calibrated to precise dimensions for uniformity, ensuring smooth engagement in windlasses and winches during mooring operations.
- Surface Treatment: To combat corrosion in marine environments, chains undergo hot dip galvanizing, black bituminous painting, or epoxy coatings.
- Quality Control and Testing: Chains undergo rigorous load testing, impact testing, and fatigue analysis and are certified by major classification societies to confirm adherence to safety and performance standards.
The combination of these processes produces studless chains that can withstand heavy loads, continuous bending, and harsh environmental conditions typical in marine and offshore applications.
Leading UK manufacturers use premium steel materials with tensile strengths tailored for heavy-duty mooring operations. Steel grades equivalent to CM370, CM490, and CM690 are common, providing excellent corrosion resistance and fatigue durability against the marine environment.
UK manufacturers ensure their studless chains meet international standards such as ISO 1704 and comply with classification societies including ABS, Lloyd's Register (LR), DNV, Bureau Veritas (BV), and China Classification Society (CCS). These certifications guarantee that the chains meet stringent requirements for strength, safety, and durability.
OEM services are fundamental in the UK chain market. Manufacturers offer customized solutions such as:
- Specific diameters and chain lengths
- Choice of steel grades for specialized environments
- Custom coatings for corrosion and wear protection
- Tailored accessories like Kenter shackles, swivel links, and end shackles

Studless chains are versatile and used widely across marine sectors such as:
- Offshore oil and gas platform moorings
- Commercial ship anchoring systems
- Fisheries and aquaculture mooring
- Naval and coast guard vessels
- Floating wind turbine mooring systems
Their flexibility and fatigue resistance suit dynamic and complex mooring configurations where frequent chain bending occurs.
Studless chains provide several benefits for certain marine applications:
- Reduced Weight: Absence of studs makes studless chains lighter, easing handling and installation.
- Greater Flexibility: Enhanced chain articulation reduces stress and wear in bending scenarios.
- Improved Fatigue Resistance: Better suited for dynamic mooring where chains endure repeated motion.
- Cost Efficiency: Generally more economical thanks to simpler design and manufacturing.
- Smooth Operation: Studless chains operate smoothly in windlasses and winches without jamming.
These advantages make studless chains particularly favorable for offshore mooring and recreational vessels, whereas stud link chains remain preferable for heavy anchor applications requiring additional link rigidity.
To endure the corrosive marine environment, UK manufacturers apply protective coatings such as:
- Hot Dip Galvanizing: A durable zinc coating that offers robust protection against rust.
- Black Bituminous Paint: Used for corrosion prevention and aesthetic purposes on aquaculture and offshore mooring chains.
- Epoxy Coatings: Provide chemical resistance and longer durability in aggressive offshore operations.
These treatments extend the service life of studless chains, reduce maintenance costs, and ensure reliable performance.
Modern UK studless chain manufacturers increasingly emphasize environmental responsibility through:
- Using eco-friendly coatings with low environmental impact
- Optimizing steel recycling and waste reduction during production
- Enhancing product longevity to reduce replacement frequency and marine pollution
This focus aligns with global efforts to support sustainable maritime operations and offshore energy projects.
