Rotomolded Marine Products
Rotational molding is a great fit for a number of marine products ranging from dock floats, jet ski docks, pontoon floats, buoys and so much more. Due to the rugged nature of rotationally molded polyethylene and the incredible buoyancy that accompanies most sealed rotomolded products, makes the rotational molding process a great fit for the plastics manufacturing process.
With the added ability of adding USCG approved urethane foaming agents to increase the buoyancy and structural rigidity of the floating marine products coupled with abilities like molded-in threaded inserts, rotational molding is an ideal process for a number of marine products.

The Sandsaver by Granger Plastics continues to demonstrate unambiguously positive results as a natural beach erosion solution.
As you can see in this series of (4) before and after pictures, it is wildly evident that the Sandsaver has accreted tens of thousands of cubic yards of sand, while increasing the width profile both North and South of the system. If you look into the foreground of the pictures you will notice an amazing increase of sand, South of the installation site.
