Niccum Docks : Built to Last
Niccum Poly Docks
Every Maintenance Free Polyethylene Dock begins with a strong steel backbone…

To ensure long life and strength our steel manufacturing process includes several advantages. To begin, we use only the highest quality steel tubing. Not all steel is the same. In fact, there are many differences in the alloy breakdown, which directly contribute to the strength and “spring” of steel tubing. To control these variables, Niccum Dock works directly with select steel mills that forge custom tubing to the exact high carbon alloy specifications set forth by our engineer. All of our tubing is high tensile strength rated and tested. All welding and fabrication of framework and welded accessories is completed in our manufacturing facility in Rockford, Minnesota. Experienced welders take time and care to assure that crucial welded seams receive a strong, long-lasting steel bond.



In addition to the welding process, NICCUM uses the highest quality custom milled steel transition stampings. These stampings are used to provide a steel transition between two pieces of tubing.



The strength of these stampings, and the welds that hold them into place are one of the most vital factors of the manufacturing process. It is for this reason that every NICCUM Dock uses the industry’s thickest gauge steel transition stamping and most thorough welds to secure their placement.



Along with the transition stampings another key component that must endure years of use and stress are the welded setscrews sockets. These sockets allow for the seasonal adjustment and installation of the NICCUM Dock System. All NICCUM set screws are custom milled and are specifically engineered with beveled edges to allow for strong weld bonds. Also, NICCUM set screw sockets are extra deep to allow increased thread travel which provides strength and long-life.

Once all of the welding fabrication is complete, all steel components are “hot dipped galvanized” to give them a corrosion proof industrial coating inside and out which prohibits rust and ensures a clean “like new” appearance for years to come. Even non-fabricated steel components such as the down pipe which is used to anchor the NICCUM Dock system to the underwater ground is pre-cut to custom lengths and then is galvanized to ensure corrosion free service for years to come.

NICCUM Maintenance Free Polyethylene Dock Systems are second to none. Years of experience and research have been poured into the development of our newest product! NICCUM Polyethylene Decks are like no other “plastic” dock on the market. To begin, NICCUM Polyethylene Decks have superior ultra-violet resistance. Special additives give NICCUM Polyethylene Decks an industry exclusive sun fade resistance, which ensures the color of the dock you buy this year will be the same for seasons to come. In addition to its superior UV resistance, NICCUM Polyethylene Docks have anti-static additives that eliminate the generation of static electricity as you walk on your dock. Along with their ability to withstand the aging power of the sun and resist the build up of static electricity, NICCUM Polyethylene Dock Systems have some very important practical advantages. First, each NICCUM Polyethylene Deck incorporates an industry exclusive SelfDrain™ system. Inherent to the manufacturing process of roto-cast plastics, the final product has an interior airspace that allows entry of water when submerged. NICCUM Polyethylene decks are the first and only roto-cast decks on the market to allow this unwanted water to drain. The NICCUM SelfDrain™ system is comprehensive inside and out! First, any water that enters the inside cavity of the deck is released through specially designed drain holes. By ensuring drainage of all interior air spaces, the potential for winter freezing and subsequent cracking and distorting is eliminated along with the chance for unwanted mold and fungus growth. One of the main complaints of polyethylene decks previously available on the market are their minimized ability to maintain a clean and like new appearance. This aesthetic deterioration brought on by dirt and fungus growth inherent to previous synthetic deck systems is corrected by the NICCUM SelfDrain™ system that eliminates the pooling of dirt and water on the deck’s surface. Each NICCUM Polyethylene deck with the SelfDrain™ system incorporates a unique gutter system that channels water from the center of the deck and effectively displaces it without pooling and without the use of drain holes away from the walking surface allowing for quick dry times after swim use or rain virtually eliminating growth of unwanted mildew caused by the pooling water and dirt. Along with the NICCUM SelfDrain™ advantage, each NICCUM Polyethylene deck incorporates our unique SureStack™ system. The SureStack™ system employs the use of integrated “stacking pins” that are structurally engineered into the bottom of each deck. The SureStack™ system allows NICCUM Polyethylene decks to be stored securely in neat and organized stacks in the off season using less storage space than any conventional synthetic deck on the market.
