Spiral Staircase Kits For Boats and Ships

Long Lasting Stairs for Your Boat or Yacht

Whether you’re looking for dock stairs or boarding stairs for your boat, you want a stair solution that won’t take up a lot of space. Staircase safety is also a major concern when dealing with stairs that will be exposed to constant moisture and different weather conditions. Salter Spiral Stair provides boat and dock stairs that feature additional safety features and will hold up to outdoor exposure.

Many boat owners maximize space by using ladders as their boarding stairs. However, these minimal frames can be a major safety hazard. Spiral stairs provide the benefits of full steps without taking up a lot of extra room. The spiral design means that your stair won’t take up more than a small circle on the back of your boat.

Salter Spiral Stair provides two different finishes for our outdoor product lines. The first is our Powder Coated Aluminum spiral stair. This custom color finish provides a modern and complementary piece for your boat that gives the already rust prohibitive aluminum a weather proof finish. Our second outdoor stair, the Galvanized Steel, is perfect for the corrosive sea air. The steel stair frame goes through a hot dipped galvanizing process that coats the stair in a maintenance free finish. Both of these stairs have a low cost of ownership and the first cost is the only cost.
