Not all composite products are created equal, and not all FRP rods are suitable for use in the construction of pontoons.
FRP thru-rods for pontoons are a highly specialized product.
The performance properties of Pultron’s FRP pontoon approved thru-rods are attributed to the composite mix, thread design, use of a specialized nut, and a thorough quality control process.
The FRP pontoon approved Thru-Rod from Pultron Composites is a highly specialized product. It was developed by Pultron in partnership with world marina builder Bellingham Marine exclusively for use in floating dock systems.
Pultron’s one-of-a-kind FRP thru-rod will not fatigue or deform under long term stress. It has tremendous tensile, shear, and thread strength. It is specially designed to withstand the dynamic forces and corrosive nature of the marine environment. The rod’s specialized performance properties are directly related to the composite mix, a unique thread design, and use of a specialized nut.
There is great variation between products within the composite industry. By definition, a composite is made up of various parts. While products from different manufacturers may look similar their physical, chemical and performance properties most likely differ.
Therefore, it is important to know the difference between an FRP rod that has been designed and approved for use in a pontoon system versus one that has not been approved.
