Double Standard Cubes
Cost-Effective – 350kg/m² Payload
 
Looking for a budget-friendly option without cutting corners on quality? Our Double Standard Cubes are the go-to solution for building large-scale floating dock systems that are tough, reliable, and built to last in Aussie conditions.
 
These standard double cubes are made from eco-friendly materials and are completely pollution-free. With a modular design, they’re quick to assemble, easy to pull apart, and can be shaped into virtually any layout – no fuss, no heavy tools needed.
 
With a heavy-duty load capacity of 350kg per m², these cubes can even handle light vehicles and equipment like small trucks or maintenance gear on your floating platform – making them a practical choice for both commercial and recreational use.
 
Not only are they stable and secure on the water, but they also look great. Available in a range of colours, you can mix and match to suit your setup or brand.
 
No ongoing maintenance, resistant to the harshest weather, and endlessly versatile – they’re a smarter alternative to timber, concrete, or metal docks. Perfect for marinas, waterfront homes, floating walkways, event stages, and more.
 
Built for big jobs. Priced for smart operators. Ready for Aussie waters.
