Outdoor spiral staircase kits are not quite as common as indoor, but still can be the perfect addition for your home. One great thing about them is that you can appreciate their looks and appeal without being in the house, so people who are driving or walking by your location can see and appreciate them.
Here will we go over some outdoor spiral staircase kits that are available on the internet.
Eureka Spiral Staircase Kit.

The Eureka Outdoor Spiral Staircase Kit is offered by Arkestairs and is available in 3 colors. Black, white or grey. It has a powder coated finish and turns clockwise or counterclockwise depending on your choice. One cool thing about this particular circular staircase is that it goes through two processes which protect it for its exterior use. The first step is an electrostatic galvanization process which is for the base protection, then they add a second protection layer of the powder coat pain. By using these methods it can last longer, and endure more. This kit is adjustable in height, and can go from about 8 feet, to 10 feet give or take. You can also get some additional parts to even extend it up to 12 feet or more. If you want the additional kits you would have to purchase them separately. The stair treads are made from solid steel and have plastic tread covers which had great durability. The handrail as well as the staircase finishes are both in a grey PVC for the white and grey choices, and the black PVC is used obviously for the black kits. This spiral staircase kit is great for outdoor use, and can be used for square, round or even mezzanine designs.
Aluminum Spiral Staircase Kit for Exterior Decks.

Considering that outside is unpredictable, and can be extreme in one degree to the other, picking the right outside spiral staircase for your deck is important. You need it to be resistant to whatever nature plans on throwing it’s way, so you simply need a tougher solution. When you go with aluminum you are headed in the right direction. While you can use them for inside, they are better used for outside areas because of how lightweight but durable they are. Also they are naturally resistant to rust which is very important in rainy climates. All of these factors make it an ideal choice for an exterior staircase kit choice.
This particular kit from Salter Spiral Stair has increased longevity because they add their own factory finish which is called powder coating and is considered to be very durable and a high quality finish. You can get the finish currently in white, black or even other custom colors. Another great quality about this spiral staircase kit is that it’s virtually maintenance free and is perfect for outdoor areas like patios or decks. Even rooftops that you need to access, if you want it to be easy, and not have to deal with bulky regular steps, save space and make it look good by using this kit.
You can choose between different tread styles which is definitely a nice feature. The different options are standard aluminum tread with closed ends, curved up aluminum tread with closed ends which provide a thin profile, long curved aluminum tread with closed ends which look more regal and elegant, code riser aluminum tread with closed ends which will take up less space and grated aluminum tread with closed ends which allows a bigger profile opening for water pass-through. You can also pick between different Tread Coverings and Balusters.
Galvanized Steel Outdoor Spiral Staircase Kit

A good choice for a metal spiral staircase kit and another great product from Salter Spiral Stair, this is a great choice for outside spiral staircases for your home or business. It’s constructed using only the most durable material, and the steel has been “hot-dipped” and galvanized is about the most durable of a choice you’re going to find for these types of stairs. The process is simple, they hot-dip the steel to galvanize it and then do the same for all of the other component surfaces as well. Then, when the stair is assembled they coat all the joints which is going to protect them great from rust.
After this is complete, and the staircase kit is fully assembled, you will have a tough, long-lasting and durable outdoor staircase that will last you a lifetime. You can choose between the basic light-grey color that comes natural, or they can primer it in whatever color you’d like. The galvanizing process makes a huge difference in how long you can expect that color to last on your stairs. It also makes a big difference in how much wear and tear your staircase will be able to take. If you’re looking for a cost-effective, durable and overall great outdoor staircase then galvanized is the way to go.
