Structure

Our aluminum stairs’ open frame structure and porous treads let waves pass through. Thru-Flow treads, made from FRP, a type of reinforced plastic, are textured to give you traction even when they are wet.

Treads

Treads are almost a full foot wide, with a 7″ rise, making them comfortable to climb. Optional side railings have a large comfortable rail for adults on top, and a smaller rail for children at the lower level. Stairs come standard at a 30° angle with 3ft wide treads, and are made to order by the number of treads you need from 2 steps to unlimited steps.

Mounting

The top sides can mount to Great Northern Docks’ Dura-LITE or Feather-LITE docks, a bulkhead, or most other platforms with the included adjustable connector. The bottom side has short adjustable pipes and feet included. If possible, these pipes should be driven into the lake bottom. If not possible, the stairs can be weighted with sand bags on the feet.

NEW Sectional Stair Design

The new design is your stairs and railings made with sections of 1, 2 or 3 step segments. This concept is more forgiving if you have a change in the gravel level in your location or measure incorrectly when ordering. You also have the option of removing the bottom end of your stairs for winter ice movement. These sectional stair segments are easy to transport by hand into the location and they stack on a pallet for affordable shipping.

Aluminum Dock Stairs

Looking for safe access to your dock or the water? Our aluminum 3 foot wide stairs provide comfortable steps with a 7 inch rise, 12 inch run, a gradual 30º slope, anti-slip surface and optional hand rails. Place on a bank to the shore with the optional Shore Mount Kit (#9700) and a ramp that closes the gap between your path and the top tread. Stairs can be attached to the top of a sea-wall or attach to the side of a dock. Leveling legs at the bottom end are included. The stair treads are made with perforated decking, (fiberglass reinforced polypropylene) with a perforated surface that allows waves to break up through and its anti-slip texture feels good under your feet. Your stairs can be ordered by the number of treads required for your specific application.

To determine the number of steps for your stairs. measure the height from the top to the bottom in inches. take that number and divide it by the number 7. Take that number and subtract one. The answer is the number of steps you’ll need. We step down from the dock onto our first step and this is why we ask you to subtract one. When measuring for your stairs, remember that each step is 12″ away from your top platform. “For example” If you calculated 8 steps, you want to measure the height 8′ away from the platform. divide that number by our 7″ rise in each step and the answer should be close to 9
Locating the spot 8′ away from the platform can be done with a long straight board extended off the top of the platform with a level. Our stairs are fixed at 30º so in some places a landing or ramp is needed to extend over and above before the stairs can pitch downward to the ground level. We know this can be a challenge in many locations so don’t hesitate to call with your questions.
