Custom Marine Fishing Chain Link Fence 316 Stainless Steel / High-Zinc Steel Wire Corrosion-Resistant for Seawater Purse Seine / Set Net / Fishing Reef Enclosure Special Net

II. Product Overview:

In marine fishing operations, fishing nets face issues such as "strong seawater corrosion, high wave impact, fish escape, easy tearing of the net body, and low efficiency due to mismatched mesh sizes." This custom marine fishing chain link fence is specifically designed to address these pain points. It can be customized based on fishing methods (purse seine, set net, trawl), target species (fish, shrimp, crab, shellfish), and operating waters (inshore, offshore, brackish water). Woven with corrosion-resistant high-strength metal wires, it features "resistance to wave impact, corrosion resistance, precise mesh size, and good flexibility," effectively improving catch rates and reducing net wear costs. It is an efficient tool for marine fishing and aquaculture enclosures.

III. Core Advantages:

Combining the characteristics of marine fishing—"harsh environment (high salt, high humidity, strong waves), high-value catches, intense operational demands, and extreme durability requirements for nets"—this product highlights its fundamental differences from ordinary fishing nets:

1. Resistant to Strong Seawater Corrosion, Withstands Long-Term Immersion

• Corrosion-Resistant Materials and Processes:
  • Primary materials include 316 stainless steel wire (containing molybdenum, with salt spray resistance more than twice that of 304 stainless steel, suitable for offshore and high-salinity waters) and high-zinc hot-dip galvanized steel wire (zinc coating thickness ≥120μm, salt spray test resistance ≥1000 hours, suitable for inshore and brackish water areas). These materials resist corrosion caused by seawater chloride ions and microbial attachment (such as algae and shellfish). Service life is 3-5 years for offshore operations and 5-8 years for inshore operations (compared to 1-2 years for ordinary nets).
  • Optional "marine-grade PVC coating" (thickness ≥1.0mm, colors available in dark blue or black to blend with the marine environment) enhances UV resistance and reduces friction damage from reefs and vessel contact.

2. High Strength and Impact Resistance, Withstands Waves and Fish Collisions

• Material Strength and Weaving Process:
  • Wire diameter ranges from 2.0-5.0mm (customized based on target species: 2.0-3.0mm for small fish and shrimp, 3.0-5.0mm for large fish). Tensile strength ≥600MPa, elongation at break ≥15%. Capable of withstanding impact from level 8 waves (tension is dispersed through the "diamond chain link structure" under force), collisions from large catches (such as tuna and sharks), and dragging from fishing gear (such as buoys and sinkers). The net body resists tearing and large-scale deformation, reducing fish escape.
• Anti-Tear Design:
  Utilizes a "double-twist encrypted chain link" process, with node engagement strength ≥90% of the net body strength. Even if partially scratched by reefs, tearing does not spread quickly, reducing the risk of "net breakage and fish escape" (40% improvement in tear resistance compared to ordinary woven nets).

3. Custom Mesh Sizes, Adapted to Target Catches and Fishing Methods

• Precise Mesh Design:
  • Mesh sizes can be customized based on "target species body size" (error ≤0.5mm):
    • Small fish and shrimp (e.g., krill, white shrimp): 1cm×1cm, 2cm×2cm;
    • Medium-sized fish (e.g., pomfret, ribbon fish): 3cm×3cm, 4cm×4cm;
    • Large fish (e.g., mackerel, tuna): 5cm×5cm, 8cm×8cm;
    • Shellfish/crabs (e.g., scallops, swimming crabs): 10cm×10cm (requires anti-escape netting).
  • Mesh shapes include diamond (low water resistance, reduces trawl energy consumption) or square (specialized for set nets, flat surface for easy fixation), balancing "efficient fishing" and "selective fishing" (e.g., avoiding juvenile fish, complying with fishery resource conservation regulations).

4. Flexibility and Operability, Adapted to Marine Operations

• Flexible and Easy to Operate:
  The chain link net body has excellent flexibility (extension rate ≥20%), reducing tangling or knotting during net retrieval and deployment. Compatible with mechanical net hauling equipment (e.g., net winches), lowering labor intensity. The net body is lightweight (30% lighter than iron chain nets of the same strength), facilitating vessel loading and handling.
• Weather Resistance and Stability:
  Withstands extreme temperatures from -20°C to 60°C (suitable for polar to equatorial waters). No brittleness at low temperatures, no coating脫落 at high temperatures, and no aging or cracking under long-term sun exposure (UV radiation), ensuring operational stability.

IV. Technical Parameters:

V. Applicable Scenarios:

• Core Operational Scenarios:
  • Purse Seine Fishing: Used for encircling pelagic fish (e.g., mackerel, sardines). Custom large-size net body (width 5-8m, length 100-200m), combined with buoys and sinkers to form an "encirclement" for efficient fish aggregation.
  • Set Net Fishing: Fixed in shallow seas or estuaries, with mesh sizes adapted to target species (e.g., swimming crabs, sea bass). Utilizes tidal currents for automatic fishing, requiring net body resistance to sediment friction.
  • Artificial Reef Enclosure: Demarcates reef areas to prevent fish dispersal while allowing small organisms to enter, creating an ecological cycle. Mesh size: 3-5cm (balancing protection and fishing).
  • Inshore Aquaculture Enclosure: Serves as an outer barrier for bottom-sown aquaculture (e.g., shellfish, sea cucumbers), blocking predators (e.g., octopuses, starfish). Mesh size: 1-2cm (prevents entry of small predators).

VI. Service Support:
