For simple fishing net rolls, a written specification may be enough.
But for customized projects such as:
Fish cage panels
Large aquaculture nets
Reinforced net sections
Special attachment layouts
a technical drawing can reduce misunderstanding much more effectively than text alone.
The key principle is:
Complex fishing net projects should use an approved drawing to define dimensions, orientation, reinforcement, seams, and attachment positions before production begins.
A written order may say:
10 m × 20 m fish cage panel with reinforced border and loops
But important questions remain:
Which side is 10 m?
Which side is 20 m?
Where are the loops?
How many loops are required?
Where do seams begin and end?
Which edges are reinforced?
A drawing makes these relationships much clearer.
The drawing should identify:
Length
Width
Depth
Panel orientation
Use clear dimension lines and units.
Avoid sending dimensions only in chat messages, especially for large customized panels.
Mesh orientation can affect:
Hanging behavior
Panel geometry
Installation
Load distribution
The drawing should show the intended mesh direction where relevant.
This is especially important for diamond mesh panels.
A customized panel should have clear orientation.
The drawing can label:
Top
Bottom
Left
Right
This helps prevent reversed installation or incorrect reinforcement placement.
If border ropes are required, mark:
Which sides are reinforced
Border rope size
Border material
Border length
Do not rely only on a note saying:
“Reinforced border.”
The exact location should be visible.
For fish cage projects, loop position is critical.
The drawing should define:
Number of loops
Spacing
Distance from corners
Loop length
Special corner loops
This makes production and later QC much easier.
If the panel contains joined sections, mark:
Seam position
Seam direction
Joining method
Seam termination
A seam in the wrong location can affect both installation and load distribution.
Special reinforcement may be required near:
Corners
Lifting points
Bottom sections
Attachment zones
These areas should be shown directly on the drawing.
This is clearer than describing them only in paragraphs.
For fish cage bottom systems, a project drawing may also identify:
Sinker connection points
Bottom attachment positions
Special loops
This helps the net manufacturer understand how the panel will interface with the wider cage system.
A useful drawing can include a small technical table showing:
Material
Mesh size
Mesh measurement method
Twine specification
Knot type
Color
Quantity
This keeps the main product requirements connected to the geometry.
Technical drawings often change during project discussion.
Every revision should be identified clearly.
For example:
Rev. 0
Rev. 1
Rev. 2
The final approved revision should be the one used for production and inspection.
Before production, both sides should confirm the final drawing.
Approval can help establish:
Final geometry
Final attachment layout
Final reinforcement
Final seam positions
This reduces later disputes about what was actually ordered.
A project drawing should include:
Product name
Overall dimensions
Units
Mesh direction
Top and bottom
Border locations
Seam locations
Reinforcement zones
Attachment loops
Loop spacing
Corner details
Material
Mesh specification
Twine specification
Quantity
Revision number
A supplier can quote more accurately when the full construction is visible.
For example, the drawing helps estimate:
Main net area
Border rope quantity
Loop quantity
Joining work
Reinforcement material
Without a drawing, different suppliers may assume different structures and provide quotations that are not truly comparable.
The same approved drawing can later be used for inspection.
QC can compare:
Actual panel dimensions
Loop positions
Border layout
Seam location
Reinforcement zones
This turns the drawing into both a production and inspection reference.
Aquaculture and engineering projects often involve multiple panels that must fit together.
A small positional error can create:
Installation delays
Misaligned attachments
Additional onsite modification
Uneven panel geometry
Approved drawings help reduce these risks before production.
The more customized the fishing net, the less reliable text-only communication becomes.
The key principle is:
Use a Written Specification to Define the Product and an Approved Drawing to Define How the Product Is Arranged.
At PL Fishery, we manufacture PE fishing nets, nylon fishing nets, fish cage panels, aquaculture netting, reinforced netting, attachment loops, custom seams, repair mesh, repair twine, marine ropes, and customized project netting.
For custom fish cage or project netting, send PL Fishery your dimensions, material, mesh size and measurement method, twine specification, panel layout, border requirements, seam locations, attachment positions, quantity, and drawing so our factory can prepare a clearer quotation and production plan.https://plfishery.com/
