Product Details
- Superior Corrosion Resistance to Saltwater & Moisture: Composed of polypropylene (PP), this rope is inherently
non-absorbent and resistant to saltwater, freshwater, and humidity.
Unlike materials that degrade or rust in marine environments, it
avoids moisture-related issues such as mildew growth, weight gain,
or fiber rot—even when continuously submerged or exposed to salt
spray. This makes it highly durable for long-term use in coastal,
offshore, or freshwater marine settings.
- Wide Diameter Range for Versatile Loads (3mm-60mm): Available in diameters from 3mm to 60mm, the rope caters to
diverse marine load requirements. Smaller diameters (3mm-10mm)
excel at light tasks like securing small gear, while larger
diameters (20mm-60mm) handle heavy-duty applications such as
mooring mid-sized vessels or towing light cargo. The 3-strand
construction ensures consistent strength across all diameter
options, with thicker strands in larger sizes enhancing
load-bearing capacity.
- Lightweight & Buoyant for Easy Water Handling: PP’s low density gives the rope natural buoyancy, allowing it to
float on water surfaces—critical for marine tasks where rope
visibility and quick retrieval are essential (e.g., marking fishing
areas, recovering gear). Its lightweight nature also reduces user
fatigue during handling, making it easy to coil, uncoil, or
transport on boats, even for larger diameter variants.
- Good Abrasion Resistance for Rough Marine Contact: The tightly twisted 3-strand structure forms a tough outer
surface that resists wear from contact with boat hulls, metal
cleats, piers, rocky seabeds, or marine hardware (e.g., winches,
hooks). It maintains structural integrity even after repeated
friction, avoiding fraying or strand breakage that would compromise
safety in tasks like docking or securing equipment.
- Cost-Effective Durability for Marine Operations: PP Danline rope offers a balance of durability and affordability
compared to premium marine rope materials. It withstands harsh
marine conditions (UV rays, saltwater, temperature fluctuations)
without frequent replacement, making it a cost-efficient choice for
both commercial marine operations (e.g., small fishing fleets) and
recreational boaters who require reliable performance on a budget.
- Recreational & Small Vessel Mooring: Suitable for mooring small to mid-sized boats (e.g., kayaks,
canoes, small fishing boats) at docks, marinas, or shorelines.
Smaller diameters (3mm-12mm) work for lightweight vessels, while
larger diameters (15mm-30mm) secure heavier craft. Its corrosion
resistance ensures longevity in saltwater, and buoyancy prevents it
from sinking if accidentally detached.
- Fishing Gear Securement & Netting: Used to secure fishing gear such as tackle boxes, bait buckets,
or fishing rods on boat decks. Smaller 3mm-8mm ropes also serve as
reinforcement for lightweight fishing nets (e.g., freshwater nets)
or as marker lines to indicate net positions. Its non-absorbent
property keeps gear dry, and abrasion resistance stands up to
friction from netting or hardware.
- Light-Duty Marine Towing & Cargo Handling: Ideal for towing small items like inflatable rafts, bait
containers, or light cargo (e.g., tools, supplies) between boats or
from boat to shore. Diameters 10mm-20mm handle these light loads
effectively, while the rope’s lightweight design makes towing easy.
Its buoyancy ensures towed items stay visible on the water.
- Dock Lines & Fender Lines: Functions as dock lines to tie boats to piers or pilings,
absorbing minor shocks from wave movement to protect boat hulls. It
also serves as fender lines—securing fenders (buoys) to boat sides
to prevent collisions with docks or other vessels. The 3-strand
structure’s flexibility allows easy knotting (e.g., cleat knots),
and UV resistance prevents degradation from prolonged sun exposure
on docks.
- Marine Marker Lines & Buoy Anchoring: Used as marker lines to indicate underwater hazards (e.g., rocks,
shallow areas), fishing spots, or swimming zones. Smaller 3mm-6mm
ropes attach to buoys, keeping markers visible above water due to
the rope’s buoyancy. Larger 25mm-60mm ropes can anchor small buoys
in calm to moderate waters, with their corrosion resistance
ensuring long-term reliability in aquatic environments.
