Double Premium Cube

Double Premium Cubes
Extra Stability – Extra Strength
 
Our Double Premium Cubes take stability to the next level thanks to their unique male/female curved locking system – delivering better strength, balance and buoyancy than standard double cubes.
 
Built tough with extra interlocking curves on two sides, these cubes offer a higher payload capacity of 350kg per m², making them ideal for drive-on/off docks and heavy foot traffic zones. The curved design also gives your dock a sleek, modern look when set up on the water.
 
Because of their extra strength and smart design, these cubes are a top pick for floating walkways, berths, pontoons, jetties, and any platform where people are coming and going regularly.
 
Available in Blue, Grey, or Orange, or choose a custom colour to suit your brand or style (minimum order of 240 cubes for custom colours). Whatever setup you’re after, these modular cubes can be easily expanded, reconfigured, relocated or dismantled to suit changing needs.
 
Maintenance-free and made from eco-friendly materials, the Double Curved Cube system is a long-term investment built to handle Aussie conditions with ease.
 
ROHS tests - The raw materials do not contain six chemicals including lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyl and polybrominated diphenyl ether, making it more conducive to human health and environmental protection.
