Aluminum and steel patio furniture is your go-to materials when you are looking for a lifetime investment for your outdoor living.

There are a lot of patio furniture options to choose from, but nothing is more durable and long-lasting than metal materials. They don’t expand or contract and their surface won’t easily crack under extreme weather conditions, while insects and decay are also not a concern.  

But between the two most durable materials which are better to suit your needs?

Aluminum vs Steel Patio Furniture

Though aluminum is not as dense and strong as steel, it is lighter. Its strength to weight ratio is 1/3 of the weight which means it’s easier to move around your patio furniture when an unexpected guest arrives or if you need to rearrange your outdoor furniture once in a while. 

When it comes to corrosion resistance, steel excels due to the chromium additives that form an invisible film around the still and is non-porous. Aluminum outdoor patio dining furniture See this aluminum outdoor dining table at Pier 1. [sponsored link]

Aluminum on the other hand has high oxidization which means when it is exposed to air or any other oxidizing agent, it will immediately develop a thin hard film made of aluminum oxide.

The film protects the surface thus making aluminum corrosion-resistant. However, the oxidized surface can dull out the color of your aluminum patio furniture. To remove the pitted look, you can easily remove it by brushing it off with soap and water. 

Aluminum patio furniture does not conduct and retain much heat compared to other metals making it a practical metal furniture choice if your outdoor furniture is in full exposure.

Steel on the other hand responds to heat or cold faster, so if your patio is located in a place that experiences extreme weather, you might want to consider another material or add some padding for steel patio seats. 

When it comes to workability, steel is very easy to weld while aluminum can be a challenge but is easier to cut than steel. 

Stainless Steel Patio Furniture Pros and Cons

Which is Better Aluminum or Steel for Outdoor Furniture?

While steel is a great option if you want to have sturdy and robust outdoor living furniture that you can leave even under stormy weather.

If heat or cold retention is your concern with steel furniture, choose to have it under a shade or add cushions and padding on your metal outdoor furniture. 

Does Cast Aluminum Rust? 

Cast aluminum won’t rust because of its solid structure. As the term implies, melted aluminum is poured into a cast which then solidifies into the shape of its mold. There is patio furniture made from metal tubes which compared to cast aluminum can easily rust with a substandard coating. 

Cast aluminum allows you to place it under the weather and you don’t need a refinishing job to maintain its rust resistance. Small patio with powder coated steel furniture

Does Powder Coated Steel Rust? 

Powder-coated steel won’t rust as long as properly prepared before a full coat is applied. It is also important to have a quality coating to prevent air or moisture to seep through the coating.

There is a curing period for each layer of powder coat to make it more permeable and prevent cracks on the surface coat.

  1. I’m voting for aluminum outdoor furniture as the best. It’s way easier to move around which is a big plus for me since I have a large patio. If it was steel I would probably throw my back out.

  2. Aluminum is clearly superior. It simply does not rust. Steel, no matter what coating applied, eventually either water vapor seeps in or there is a chip to the coating and your get rust under the coating creating a bubble appearance.

    Now, I take issue to the cost. Although Aluminum is cheaper than steel ($0.08 per ounce vs $0.55/oz steel – as of this writing august 2021), aluminum patio furniture tends to be more expensive. This is the reason Im on this site in the first place.

  3. I am looking at outdoor chaise lounges for my pool area
    The chaise I am looking at is made or distributed by Roiyieir and it says it is cast aluminum rust resistant . When I look closer in the description it says it has a steel frame. I do not understand how it can be cast aluminum with a steel metal frame.
