Our Aluminum Spiral Stair is an aesthetically pleasing solution for traveling from your deck to a lower level and can really accent the look of your home. Our Aluminum Spiral Staircase has a special powder coating, which has been tested by time and proven to work for decades all over the country, even in beach towns where the salt is relentless.
Aluminum is the perfect material to resist rust in tough environments. When you powder coat, your spiral stair will last for years with, no maintenance required.

BALCONY & DECK RAILS

Another consideration when purchasing an aluminum stair is railing for your deck or balcony. Railing is intended as a safety feature to protect people from falling, but it can be coordinated to match the stair railing and fit into your overall style. Although you may choose a stair with a wide baluster spacing, the balusters on the balcony and deck railing are spaced at 4″ or less, which is what the national building code requires.
