Grade 3 Studless Anchor Chain

As a national high-tech enterprise and a provincial specialized and innovative enterprise, CSAC Chain not only supplies products but also delivers quality assurance backed by certifications from major international classification societies.

Product Overview

Our Grade 3 Studless Anchor Chain is manufactured from high-quality marine steel using advanced flash butt welding technology. Compared with stud link chains, the studless design reduces the overall weight of the chain while improving flexibility and storage efficiency in limited chain locker space.

Key Features of Grade 3 Studless Anchor Chain

1. Optimized Structure and Space Efficiency

The studless structure eliminates the risk of loose studs and provides a smoother chain surface. This design reduces friction when passing through the windlass gypsy and allows tighter stacking inside the chain locker, which is particularly beneficial for vessels with limited deck space.

2. High-Strength Materials and Marine Durability

The Grade 3 Studless Anchor Chain is produced from high-strength marine alloy steel with strong resistance to seawater corrosion and cyclic fatigue. Combined with specialized heat treatment processes, the chain maintains structural integrity and toughness even in deep-sea environments.

3. Precision Manufacturing Process

With automated welding production lines and strict dimensional control, Zhoushan Zhongnan Anchor Chain ensures each link meets ISO standards. This consistency guarantees smooth operation during anchoring and reduces the possibility of chain jumping or jamming in the windlass system.

Frequently Asked Questions (FAQ)

What is the difference between Grade 3 and Grade 2 anchor chains?

Grade 3 chains have higher yield strength and breaking load compared to Grade 2 chains. Under the same diameter, Grade 3 provides stronger load capacity, allowing ships to use lighter chains while maintaining safety requirements.

Where is Grade 3 Studless Anchor Chain typically used?

This chain is commonly used in offshore energy platforms, FPSO units, floating wind power systems, and research vessels where strength-to-weight ratio is important.

Do you supply anchor chain accessories?

Yes. Zhoushan Zhongnan Anchor Chain provides compatible accessories including Kenter shackles, D-type connecting shackles, swivel shackles, and other mooring components to ensure complete anchoring systems.
