Marine Anchor Chains Price U2 U3 Grade Stud Link Anchor Chain for
Ship
Designed exclusively for the demanding conditions of marine
operations, our U2/U3 Grade Stud Link Anchor Chain stands as a reliable core component for ship anchoring, mooring,
and positioning—suitable for commercial vessels, cargo ships,
tankers, offshore platforms, and large recreational boats.
Engineered to meet international marine standards and withstand
extreme loads, corrosion, and harsh seawater environments, this
anchor chain delivers uncompromising safety and durability for
critical maritime tasks.
1. Core Specifications & Grade Advantages
Grade Classification: U2 & U3 for Targeted Performance
- U2 Grade: Optimized for medium-duty marine applications (e.g., coastal
cargo ships, fishing vessels, and mid-sized yachts). It offers
excellent tensile strength (minimum breaking load per chain size
compliant with ISO 1704 standards) and impact resistance, balancing
performance and cost-effectiveness for regular coastal or
short-haul voyages.
- U3 Grade: Engineered for heavy-duty and offshore use (e.g., deep-sea
tankers, bulk carriers, offshore supply vessels, and drill ships).
With a higher carbon-manganese steel composition, U3 Grade provides
superior tensile strength (up to 20% higher than U2 in equivalent
sizes) and fatigue resistance, enduring long-term exposure to
strong currents, high winds, and heavy anchor loads in deep waters.
Stud Link Structure: Enhanced Stability & Load Distribution
Featuring a stud link design (each link equipped with a central stud), this anchor chain
eliminates link deformation under heavy tension—preventing
"kinking" or "bending" that can compromise structural integrity.
The stud also ensures uniform load distribution across each link,
reducing stress concentration and extending the chain’s service
life, even during repeated anchoring cycles.
Standardized Sizes & Customization
Available in a full range of sizes (from 16mm to 120mm link
diameter) to match vessel displacement, anchor weight, and
anchoring depth requirements. All sizes adhere to global marine
standards (ISO 1704, ABS, DNV, LR, or BV certifications, based on
customer needs). For specialized projects (e.g., custom-length
chains for offshore platforms), we offer tailored cutting,
end-fitting (e.g., connecting shackles, swivels), and
surface-treatment options to meet unique operational demands.
2. Marine-Grade Performance & Durability
Corrosion Resistance for Seawater Environments
All chains undergo hot-dip galvanization (HDG) or epoxy coating (optional for extreme saltwater conditions) to form a protective
barrier against seawater, salt spray, and marine organisms (e.g.,
barnacles). The HDG layer ensures resistance to rust and corrosion,
maintaining structural strength even after years of submersion or
exposure to harsh marine atmospheres—reducing maintenance frequency
and replacement costs.
High Tensile Strength & Impact Resistance
Manufactured from high-quality low-alloy steel, the chain undergoes
precision forging and heat treatment (quenching and tempering) to
achieve exceptional tensile strength and toughness. It can
withstand sudden impact loads (e.g., during rough seas or emergency
anchoring) without fracturing, ensuring reliable performance in
critical situations. Each chain is factory-tested for breaking
load, elongation, and hardness to meet or exceed grade
requirements—with test reports provided for quality verification.
Anti-Wear & Anti-Fatigue Properties
The link surfaces are smoothed and deburred during production to
minimize wear from contact with anchor windlasses, hawse pipes, or
seabed rocks. The U3 Grade variant further incorporates
micro-alloying elements to enhance fatigue resistance, making it
suitable for vessels that require frequent anchoring (e.g.,
ferries, offshore service ships) or long-term mooring.
3. Compliance & Safety
International Marine Certifications
All U2/U3 Grade Stud Link Anchor Chains are certified by leading
classification societies (ABS, DNV GL, LR, BV, or CCS) to ensure
compliance with maritime safety regulations (SOLAS, MARPOL). This
certification guarantees that the chain meets strict standards for
design, material, and performance—providing peace of mind for ship
owners, operators, and marine engineers.
Safety-Centric Design Features
- Uniform Link Dimensions: Ensures smooth operation with standard marine anchor systems
(windlasses, capstans) to prevent jamming or equipment damage.
- Traceability: Each chain is marked with grade, size, certification, and batch
number for full traceability—simplifying maintenance records and
compliance audits.
- Load Capacity Labeling: Clear labeling of working load limit (WLL) and minimum breaking
load (MBL) on each chain segment to prevent overloading and ensure
safe operation.
4. Application Scope
Ideal for a wide range of marine vessels and scenarios:
- Commercial ships (cargo ships, container ships, tankers, bulk
carriers).
- Offshore vessels (offshore supply ships, drill ships, wind farm
support vessels).
- Recreational boats (large yachts, cruisers).
- Fixed marine structures (offshore platforms, floating docks, buoy
systems).
Whether for primary anchoring, secondary mooring, or emergency
positioning, this U2/U3 Grade Stud Link Anchor Chain delivers the
reliability and performance required to keep vessels secure in all
marine conditions.
5. Quality Assurance & Packaging
- Quality Control: Each chain undergoes rigorous inspection (visual checks,
dimensional measurements, tensile testing, and corrosion resistance
testing) before shipment to ensure zero defects.
- Secure Packaging: Packaged in seawater-resistant wooden crates or steel drums to
protect against damage during transit (e.g., moisture, impact). For
bulk orders, we offer containerized shipping with custom bracing to
prevent shifting.
Choose our U2/U3 Grade Stud Link Anchor Chain for a robust,
compliant, and long-lasting solution that meets the toughest marine
anchoring challenges—backed by our commitment to quality and
customer satisfaction.
