Aluminum Stairs

Looking for safe access to the water from your dock or shore?

Great Northern Docks’ aluminum stairs are the answer.

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 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.

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.

Stair attachment and mounting methods

A vertical track at the top of all one-piece stairs on each side for the head of a 3/8″ carriage bolt. We use this for the ability to adjust the gap between the top of a 5″ Feather-LITE™ or 6″ Dura-LITE™ stationary dock frames and the first step of the stairs.

Optional Shore Mount Kit. This kit mounts to the vertical track at the top of the stairs and provides a pipe socket on each side for standing the stairs on our standard dock legs. The socket has set screws for height adjustment along with mounting pins for a small ramp that will provide an additional step on top and reach to the ground. The ramp can pivot on these pins while you adjust the height of your stairs.

Tabs. Tabs mount to the vertical track for bolting directly to the face of your existing dock, wall, deck, landing, or other platform.

Swing Up Hinge. Many customers in tidal areas want to swing their stairs up for storage and drop them back down when in use. The swing up hinge bolts to the end of the dock, pier, or bulkhead. The connecting pins can be taken out for removal or remain in to allow the stairs to be swung up.

Sectional, Marine-Grade, Modular Aluminum Stairs

The modular design allows these stairs and railings to be 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 if you are unsure about measurements. You also have the option of removing lower segments of your stairs to avoid winter ice movement. These sectional stair segments are easier to transport by hand to their final location and stack on a pallet for more affordable shipping.
