What This Product Is For
DIN766 Aquaculture Mooring Fishing Chain is a welded short link chain in 16*48mm size, zinc plated for saltwater service and supplied at 5.7 kg per metre. It is used to moor fish farm cages and net pens, and as conveyor chain in processing lines. Fish farm operators buy it by the drum when existing mooring lines corrode through before the end of a grow-out cycle.
Key Benefits
- Zinc plated (galvanized) finish slows corrosion in permanent saltwater immersion and extends replacement intervals
- Welded link structure keeps the chain intact under the constant cyclic loading of tide and wave movement
- Available in Grade 50, Grade 60 and Grade 80 so mooring loads can be matched without oversizing the chain
- Stocked against a 100 metre MOQ, so a single cage line can be replaced without a full container order
Problems It Solves
- Untreated chain rusts through mid-cycle and forces unplanned cage recovery
- Mixed grades on site make it hard to confirm the line is rated for the design load
- Small farms cannot commit to container quantities for a single mooring refit
Application Scenarios
- Bottom mooring lines for offshore fish farm cages
- Net pen and marine culture raft anchoring in tidal water
- Conveyor chain runs inside seafood handling and processing lines
- Riser and bridle sections between mooring anchors and cage collars
Who It Is For
- Aquaculture and marine culture farm operators replacing mooring gear
- Marine contractors installing cage and raft mooring grids
- Fishing gear distributors supplying farms in coastal regions
Technical Features
- Manufactured to DIN763, DIN764 and DIN766 dimensional standards
- Alloy steel base material with anti-corrosion treatment
- 16*48mm link size, 5.7 kg/m nominal weight
- Welded round link form suited to sheave and sprocket contact in conveyor use

Customization Options
- Grade 50, Grade 60 or Grade 80 to suit the mooring design load
- Cut and drum lengths to match individual cage lines
- DIN763, DIN764 or DIN766 pitch depending on the existing gear on site
Quality Control
- Dimensional check on wire diameter and pitch against the declared DIN standard
- Weld integrity inspection on the link seam before surface treatment
- Zinc coating verified before packing and shipment
How It Compares With The Alternatives
Compared with Self-colour mild steel chain
The zinc plated finish is the reason this chain is chosen for permanent immersion, where self-colour chain starts rusting within the first season
Compared with Long link chain of the same wire diameter
The DIN766 short pitch gives a more compact line that runs cleanly through sprockets and fairleads instead of twisting
How To Use And Maintain It
- Confirm the grade required by the mooring design before ordering, since Grade 50, 60 and 80 differ in working load
- Match the pitch standard to the shackles and connectors already on site
- Inspect the immersed section for coating loss at each cage inspection dive
- Replace the full line rather than splicing in a section of a different grade
What We Need From You To Quote
- Size or diameter, and the grade if it is specified
- Quantity and packing format
- Surface finish for the environment it works in
- Classification society, if a certificate is required
- Destination port for freight
