Product Description:

Material Advantages:

Manufactured from premium high-tensile carbon steel (Q345/Q235) and optional 316/316L stainless steel for extreme corrosion resistance
Finish options: hot-dip galvanization (primary, for long-term saltwater anti-corrosion), black bituminous paint, custom marine coatings
Distinctive two large triangular flukes with 32° standard shank angle (adjustable to 45° for hard sand/soft mud); reinforced I-beam fluke structure and high-strength steel shank ensure maximum penetration and holding force
Foldable stock design for space-saving stowage on deck, simplified deployment and retrieval

Manufacturing Process:

The production process of Admiralty Anchors strictly adheres to marine anchor casting standards and offshore mooring equipment strength requirements, centered on “structural precision, material strength and toughness, and corrosion resistance compliance.” Specific steps are as follows:

### 1. Raw Material Preparation and Mold Design
- Select high-strength cast steel (ZG230-450) or premium marine carbon steel. Ingredients are blended according to chemical composition requirements to ensure compliance with carbon, manganese, and other elemental content standards, enhancing tensile strength and toughness.
- Design sand molds based on anchor specifications (weights ranging from 500kg to 50t). The mold cavity precisely replicates the naval anchor's “four-fluke crown + crossbar” structure. Thickened sections are incorporated at the anchor fluke-to-shank junctions. Mold inner walls undergo polishing to prevent surface defects in castings.

### 2. Monolithic Casting
- Molten cast steel (1500-1600°C) is injected into the mold via a pouring system using gravity casting. This ensures uniform filling without dead zones or porosity.
- After natural cooling to room temperature, the mold is opened to remove the anchor blank. Gates, risers, flash, and other excess material are trimmed to prevent residual stress-induced cracking.

### 3. Structural Reinforcement and Precision Machining
- Critical load-bearing areas like anchor claws and crown undergo forging reinforcement to enhance localized hardness and impact resistance. Claw edges are ground to ensure sharpness and improve seabed gripping efficiency.
- Machine the connection hole at the top of the anchor body (to match anchor chain specifications). Bore the hole walls smooth to ensure secure chain attachment. Secure the crossbar via welding or integral casting. Apply full-penetration welding at joints and perform non-destructive testing.

### 4. Surface Anti-Corrosion Treatment
- Perform sandblasting rust removal first to thoroughly eliminate surface scale, rust, and oil contamination, achieving Sa2.5 standard to enhance coating adhesion.
- Apply a dual-layer coating of “epoxy zinc-rich primer + marine-grade topcoat” (total thickness ≥150μm) or utilize hot-dip galvanizing (zinc coating thickness ≥85μm). Both methods effectively resist offshore seawater corrosion and salt spray erosion.

### 5. Finished Product Inspection and Quality Control
- Visual Inspection: Verify anchor body is free of cracks, pores, pinholes, or other defects. Structural dimensional deviation ≤ ±3%. Anchor fluke symmetry and crossbar verticality meet design requirements.
- Performance Testing: Conduct tensile strength testing (≥400MPa) and impact toughness testing. Perform simulated holding force tests on samples to verify holding force meets standards (≥8 times its own weight).
- Corrosion Resistance Testing: Pass salt spray testing (1000 hours continuous) to evaluate coating or galvanized layer durability, meeting offshore long-term service requirements.
- Compliance Certification: Products must obtain certification from classification societies such as CCS and ABS, ensuring compliance with GB/T 5468-2019 “General Technical Conditions for Marine Anchors” and offshore mooring equipment standards.

### 6. Packaging and Shipping
- Packaged securely on wooden pallets or steel frames to prevent deformation during transit. Anchor bodies are wrapped in moisture-proof film to protect anti-corrosion coatings.
- Includes product inspection reports, certification documents, and installation manuals for seamless offshore project integration or on-site deployment.

Features:

Key Structure: Features two large triangular flukes set at a fixed 32° angle to the shank, with I-beam fluke construction and a reinforced crown plate yoke to ensure stable fluke orientationdanforthanchors.com. The foldable stock allows flat stowage, saving deck space.
Holding Performance: Flukes dig deep into sand/mud seabeds, delivering holding power 10–15 times its weight (e.g., a 50 kg anchor can hold ~500–750 kg force).
Operational Efficiency: Lightweight design enables easy deployment, retrieval, and handling; ideal for vessels with limited deck equipment.
Cost-Effective: Lower material consumption and simple manufacturing reduce costs while maintaining reliable performance.

Full range of sizes from 20kg up to 6000kg; custom dimensions available upon request
Complete certification package for vessel class approval
Packaging: seaworthy wooden crates, steel frames; delivery terms: FOB, CFR, CIF, EXW

Technical Parameters:

Applications:

Optimal Seabeds: Sand, mud, sand-mud mixtures; sharp flukes ensure quick penetration and stable grip.
Limitations: Poor performance on rocky, weedy, coral, or clay seabeds; may “kite” over uneven bottoms in strong currents.
Vessel Suitability: Primary/auxiliary anchor for small-to-medium boats, yachts, workboats, barges, tugs, and coastal cargo ships; not recommended for deep-sea ocean-going vessels.
Scope Requirement: Minimum 5:1 scope (7:1 in rough seas) for full holding power.
