Aluminum or Steel Spiral Staircase – Which One to Choose?

Aluminum and steel are two of the most common metals used for manufacturing spiral staircases. It is important to compare the benefits and drawbacks of each metal option before choosing one or the other for your spiral staircase. At UglyDeck, we offer an array of options when it comes to outdoor spiral staircases. Chicago homeowners can choose from aluminum or steel designs that will enhance the décor and functionality of any deck or backyard area.

Aluminum

With its corrosion-resistant and lightweight features, aluminum is an ideal choice for an outdoor spiral staircase. Chicago residents will find that aluminum is more affordable than other metal options and has an appealing appearance. It is also easy to clean. One disadvantage is that the material is not as strong and durable as steel. It doesn’t handle vibrations as well as steel and is more likely to bend or even break than its steel counterpart.

Steel

The strength of steel makes it an ideal structural building material, including for outdoor spiral staircases. The malleability of steel makes it bendable with reducing its strength or causing it to break. Steel is an ideal choice for manufacturing the curved features of outdoor spiral staircases. It is also highly durable, but it does require more regular weatherproofing to prevent rust than aluminum.

Aluminum vs. Steel Comparisons

Many homeowners appreciate the appearance provided by an outdoor spiral staircase made of aluminum because it looks less industrial than steel. You can also add a powder coating in one of various color options or solid wood handrails and tread covers to match the deck. You can paint galvanized steel, but the maintenance requirements will be higher than for a powder coated aluminum staircase.

Any outdoor structure must be resistant to the weather elements. Aluminum is an optimal material for this purpose, making it the metal of choice among homeowners for outdoor spiral staircases.
