A spiral stair could be your answer to new levels of fun at the lake! Our Lake Way stair is servicing the second story of a boat house. On top is a deck used for personal leisure or for personal play. The Lake Way was fabricated out of all aluminum for this specific water application. Being all aluminum, this stair is not susceptible to rusting or corrosion. Some other benefits is that the stair keeps cool in hot conditions and is a fraction of the weight of a steel stair.
