HDPE is Inert!

It’s great for making chemical storage tanks.

Polyline Industries design and manufacture customised poly barges & pontoons for the Mining, Marine, and Oil & Gas industries. A range of floating platforms can be built for jetty’s, walkways, floating pump landings, work platforms, plane/helicopter/boat landings, houseboats, party boats – the list goes on!

Our Barges and Pontoons are fabricated using Polyethylene (Poly or PE or Plastic as commonly referred to) which by nature has these great qualities:

HDPE is more buoyant than water and assists in the floatation of the vessel resulting in lower possible vessel weights and improved fuel economy.

HDPE is UV stable and does not corrode giving the pontoon a life expectancy of up to 100 years (colour dependent).

Does not require sealing, painting or anti-fouling to prevent marine growth. To clean it just use a high-pressure cleaner. Consider the cost-saving on this alone!

HDPE barges & pontoons are a safe platform choice as they’re 100% watertight and designed according to your requirements. 

For a similar price to aluminium, the advantages of HDPE barges & pontoons far outweigh the benefits of an aluminium floating platform.

Our Range

21 Meter Barge

21 Metre Barge

The “Responder 3” is a 21m x 13m modular barge and to our knowledge is the largest poly barge built in the world. In 2C survey, the barge was designed to be built into modules for ease of transport. It is currently operating off the north cost of Western Australia.

Class: 2C
LOA: 21.25m
Measured Length: 21.00m
Moulded Beam: 13.28m
Displacement: 300t
Waterline Length: 21.0m
Waterline Beam: 13.28m
Hull Draft: 1.28m
Vessel Speed: N/A
Pax/Crew: N/A

8 Meter Barge

Named the “Hardship 3” this 8 meter barge was designed and built as a working platform at Koolan Island (Kimberley coast of Western Australia). Outboard motors were fitted to the barge so that the working personnel could install anchors around the island.

Moulded Beam:3.55m
Design Draft: 0.25m
Propulsion:2 up to 60hp each engine
Survey:Exempt or 2C
People:Up to 12
Capacity:4 tonne

Pontoons For Party Boat

Polyline design, repair and fabricate the poly pontoons for leisure vessels such as a Party Pontoon.  Custom variations can be accommodated to suit your requirements (without adding extraordinary costs to the project).

Additional benefits of Pontoons for Party Boats
  • HDPE Pontoons increase the weight of the party boat equating to a more comfortable ride (wont bob around like a cork)
  • An increased displacement and weight means if a group of people move to one location the vessel is less effected (wont nose dive when everyone runs to the bow of the barge to see the Dolphin)
  • The cost to manufacture is very similar to replacement aluminium pontoons 
  • Extended life expectancy as Poly will not corrode. There’s also no need to anti-foul
