It sounds like you’re looking for lead lines (also known as leaded lines or sinking lines) for commercial fishing, ranging from 10 grams per meter (gr/m) to 5000 gr/m in weight. Here’s a breakdown and what you might want to consider:

🎣 What Are Lead Lines?

Lead lines are ropes or cords that have lead integrated into them, commonly used in:

• Gillnets and trammel nets to ensure they sink properly.

• Longlines to keep baited hooks submerged.

• Trawl and seine nets for weight and control.

• Aquaculture and mooring lines as ballast.
