Key Benefits & Features


Superior Structural Rigidity

The stud anchor chain’s integrated stud design reinforces each link, preventing twisting or deformation under heavy loads. This structural rigidity ensures consistent anchoring performance, even in rough seas or high-wind conditions.

Exceptional Wear Resistance

Manufactured from high-tensile steel with specialized surface treatments, this marine anchor chain resists abrasion from seabeds, rocks, and mooring equipment. Its durable construction minimizes wear over time, extending service life and reducing replacement costs.

Multi-Grade Versatility

Offered in Grade 1, Grade 2, and Grade 3 options, the stud anchor chain caters to diverse marine needs—from lightweight vessels to heavy-duty ships. Each grade is engineered to meet specific load requirements, ensuring optimal performance for every application.

Easy Installation & Compatibility

Designed for seamless integration with standard marine anchors, shackles, and winches, the ship chain simplifies installation and maintenance. Its uniform link dimensions ensure compatibility with existing mooring systems, reducing downtime for vessel operators.

Stringent Quality Control

Every stud anchor chain undergoes rigorous quality inspections, including tensile strength tests, dimensional checks, and corrosion resistance assessments. This commitment to quality guarantees reliable performance and compliance with global marine standards.

FAQ


What nominal diameter options are available for the stud anchor chain?

Our stud anchor chain ranges from 12.5mm to 172mm (1/2” to 6-7/8”), covering the needs of small boats to large commercial vessels. Custom sizes can be arranged for specialized applications.

Which grade of stud anchor chain is suitable for large cargo ships?

Grade 3 is recommended for large cargo ships and heavy-duty vessels, as it offers the highest tensile strength and load-bearing capacity. Grade 1 and 2 are ideal for smaller vessels and light to medium-duty applications.

Does the stud anchor chain require regular maintenance?

While the chain is designed for low maintenance, periodic inspections for corrosion, wear, and link damage are recommended. Cleaning with fresh water after saltwater exposure helps preserve its anti-corrosive properties.

Is the stud anchor chain compatible with all types of marine anchors?

Yes, the marine anchor chain is designed to be compatible with standard anchors (e.g., fluke, plow, and mushroom anchors) and mooring equipment, ensuring versatility across different vessel types.

What certifications does the stud anchor chain hold?

The chain is certified by DNV, ABS, LR, BV, NK, KR, CCS, RINA, RS, and IRS, meeting global marine safety and quality standards for shipping and offshore operations.
