The Studless Anchor Chain is a cornerstone of reliable marine mooring systems, engineered to meet the rigorous demands of commercial shipping, offshore operations, and marine engineering projects. As a core component of ship anchoring systems, this marine anchor chain eliminates the traditional stud design while retaining exceptional strength and durability, making it ideal for vessels of all sizes—from small cargo ships to large tankers and offshore support vessels. Crafted with precision, our studless link anchor chain adheres to strict international specifications, ensuring seamless compatibility with standard anchoring hardware. Whether navigating rough seas or maintaining long-term mooring, this heavy-duty marine chain delivers consistent performance, minimizing downtime and enhancing operational safety. With a nominal diameter range of 12.5mm to 172mm (1/2” to 6-7/8”), it caters to diverse marine applications, while customizable options allow tailoring to specific vessel requirements.
Parameter | Details |
Link Type | Common Studless Link, Enlarged Studless Link, End Studless Link |
Nominal Diameter (d) | Common: 12.5mm ~ 172mm (1/2” ~ 6-7/8”); Enlarged: 1.1×d; End: 1.2×d |
Length (L) Formula | Common: L = 6×d; Enlarged: L = 6.6×d; End: L = 6.75×d |
Width (W) Formula | Common: W = 3.6×d; Enlarged: W = 3.96×d; End: W = 4×d |
Material Grade | Grade 1, Grade 2, Grade 3 (high-tensile steel) |
Tensile Strength | Grade 1: ≥460MPa; Grade 2: ≥620MPa; Grade 3: ≥800MPa |
Surface Treatment | Hot-dip galvanization, anti-corrosion painting (customizable) |
Standard Compliance | ISO 1704, GB/T 549, ABS Rules for Building and Classing Steel Vessels |
Manufactured from premium high-tensile steel, our Studless Anchor Chain boasts exceptional load-bearing capacity, resisting extreme tension and impact during anchoring and mooring. Grade 3 variants, in particular, are engineered for offshore and heavy-duty applications, ensuring reliability in harsh marine environments.
The three link types—Common, Enlarged, and End Studless Links—offer tailored solutions for different parts of the anchoring system. Enlarged links enhance connection stability, while end links ensure secure attachment to anchors and windlasses, making this ship anchor chain a flexible choice for diverse setups.
Every studless anchor chain strictly adheres to global specifications such as ISO 1704 and GB/T 549, guaranteeing interoperability with international anchoring equipment. This compliance simplifies cross-border operations and meets the requirements of major port authorities.
We offer custom marine anchor chain solutions, including tailored lengths, surface treatments, and material grades, to match unique vessel designs and operational needs. Whether modifying diameter or adjusting corrosion resistance, our engineering team delivers personalized results.
Hot-dip galvanization and optional anti-corrosion coatings protect the chain from saltwater, humidity, and marine fouling, extending its service life and reducing maintenance costs. This durability ensures long-term reliability in both coastal and deep-sea environments.
Ideal for cargo ships, container vessels, and bulk carriers, providing stable anchoring during port calls, loading/unloading, and emergency stops.
Essential for offshore supply ships, drill ships, and wind farm support vessels, ensuring secure mooring during offshore construction and maintenance.
Meets the high-safety requirements of oil tankers, LNG carriers, and chemical tankers, with Grade 3 options handling the heavy loads of hazardous cargo vessels.
Used in floating docks, offshore platforms, and bridge construction, serving as a reliable mooring solution for stationary marine structures.
Our Studless Anchor Chain holds certifications from leading global maritime authorities, including DNV certified anchor chain, ABS approved anchor chain, LR (Lloyd’s Register), BV (Bureau Veritas), NK (Nippon Kaiji Kyokai), KR (Korean Register), CCS (China Classification Society), RINA, RS (Russian Maritime Register), and IRS (Indian Register of Shipping). These certifications validate compliance with international safety and quality standards, giving vessel operators confidence in every deployment.
Our chain covers a range of 12.5mm to 172mm (1/2” to 6-7/8”), suitable for vessels from small fishing boats to large ocean-going ships.
Yes, we offer custom marine anchor chain lengths to match your vessel’s specifications. Contact our team to discuss your required length, link type, and surface treatment.
Absolutely. Our studless anchor chain is designed to fit standard anchors and windlasses, complying with international interoperability standards.
Hot-dip galvanization provides 5-8 years of corrosion resistance in typical marine environments. Optional anti-corrosion coatings can extend this to 10+ years.
Grade 3 is recommended for offshore use, as it offers the highest tensile strength (≥800MPa) and durability for extreme conditions.
