Dura Float Modular Pontoons offer flotation for a wide variety of uses. The seamless, one-piece hull is made of ultraviolet stabilized, high-impact polyethylene. Molded-in colors will not chip or peel. Impact resistance exceeds that of steel or aluminum. Pontoon surfaces are smooth and resistant to algae growth. To prevent sinking in the event of fracture, the interior is composed of high-density closed cell polyurethane foam. Dura Float Nose Cone Modules may be placed at the end of either a pontoon section or a series of body modules. They are used when constructing a pontoon boat or other navigable structure.
