What This Product Is For
DIN764 Aquaculture Mooring Fishing Chain is a welded medium link chain in 16*48mm size, zinc plated for saltwater service and weighing 5.7 kg per metre. The DIN764 pitch sits between DIN763 and DIN766, and is used for fish farm cage mooring, marine culture rafts and as conveyor chain in processing lines.
Key Benefits
- DIN764 medium pitch matches the connectors already used on many existing cage mooring grids
- Zinc plated finish slows corrosion in permanent immersion and extends the replacement interval
- Grade 50, 60 and 80 options let the chain be rated to the actual mooring load
- 100 metre MOQ with samples available, so a single line can be trialled before a full refit
Problems It Solves
- Mooring chain corroding through before the end of a grow-out cycle
- Pitch mismatch between new chain and existing shackles and connectors
- Suppliers unwilling to quote below container quantities
Application Scenarios
- Cage and net pen mooring in marine aquaculture
- Raft and longline anchoring in marine culture sites
- Conveyor chain duty in seafood processing
- Bridle sections between mooring anchors and cage frames
Who It Is For
- Fish farm operators refitting mooring grids
- Aquaculture equipment suppliers and installers
- Distributors serving coastal fishing and farming regions
Technical Features
- Produced to DIN763, DIN764 and DIN766 dimensional standards
- Alloy steel with anti-corrosion treatment
- 16*48mm size, 5.7 kg/m nominal weight
- Welded round link structure

Quality Control
- Pitch and wire diameter checked against the DIN764 table
- Weld seam inspection before surface treatment
- Zinc coating verified before packing
How It Compares With The Alternatives
Compared with DIN766 short link chain
DIN764 has a longer pitch, which is easier to handle by hand but less compact through a sprocket
Compared with DIN763 long link chain
DIN764 is the middle pitch, giving more stability than DIN763 at the same wire diameter
How To Use And Maintain It
- Confirm the grade against the mooring design load before ordering
- Match the DIN pitch to the shackles already installed
- Check coating loss on the immersed section at each inspection dive
- Replace whole lines rather than splicing mixed grades
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
