Aluminum vs Steel Above Ground Pools

Aluminum vs Steel Above Ground Pools

It’s not as big a question as it was six or eight years ago, but I still get a fair amount of people asking about aluminum above ground pools. The main reason anyone would consider an aluminum over a steel above ground pool is to avoid rust. This is definitely true as aluminum won’t rust. Rust is a term that is used only for the oxidation of iron and aluminum has no iron. It will corrode, though, so there’s not much to gain in getting an aluminum pool, but it’s worth going over the pros and cons just in case your heart is set on getting one.

If you don’t want to read this whole article just to get my opinion, then no worries. I’ll give it to you right now. In the general sense, aluminum pools are not worth the extra cost. Now, if you have the time to find out why, read on.

The Different Types of Aluminum and Steel Above Ground Pools

There are about six variations of aluminum and steel pools and they each have pluses and minuses. Let’s go over them. Shall we?

I. All aluminum pool

This is an above ground that has every part of it made of aluminum. The wall, top and bottom tracks, all the connectors, stabilizer bars, top rails, uprights, and top caps are 100% aluminum. These pools are usually nicer than average and are a lot more expensive.

II. All steel pool

All steel pools aren’t as common as before, but there are still quite a few of these manufactured. They have steel walls, tracks, connector plates, uprights, stabilizer bars, top rails, and top caps. These are mostly the lower-end models of above grounds.

III. Part aluminum, part steel pool

There are some variations here, but mostly these pools will have aluminum top rails and caps and the rest is steel. These aren’t too bad, because they have steel walls. They can still be quite a bit more expensive, though.

IV. Part steel, part resin (aka hybrid above ground pools)

This is the most popular type of above ground today. Almost all of them will have steel walls, but there are various combinations of resin and steel parts. Some will have resin bottom tracks and/or resin connector plates. Some will have resin uprights with steel bottom tracks. Most of these, though, come with resin top rails and caps with everything else being made of steel. Overall, this is my favorite combination.

V. Part aluminum, part resin

This isn’t a super common type, but I do see these. They mostly have aluminum walls, top connectors, and stabilizer bars combined with resin top rails. These are not my favorite as they have aluminum walls and are still pricey for what you get.

VI. All resin pool

I hear this term a lot and it’s not accurate. Resin material is plastic and is in no way strong enough to hold the pool water. So, an all resin pool still has to have a wall made of metal. And they almost all have steel walls. So, an all resin pool really is a pool that has every part of it made of resin, except the wall.

Also, some pools that are called “all resin” will still have some steel parts like connector plates and steel screws. The only model that comes to mind that is truly all resin (except of course the wall) is one called the Matrix by Wilbar.

VII Extruded aluminum wall pool

This type of above ground has quite a different wall from the others. The other pool walls are one continuous piece while this one comes in sections that interlock together.  The wall sections are made of extruded aluminum which makes them stronger and thicker. The extra thickness is very important in that this wall could never corrode enough to make the wall fail and not hold the water of the pool.

This pool is considerably more expensive than the others and the only real difference is the wall. Manufacturers sell this as a semi in-ground pool and that’s why it has that fancy wall system. The wall is strong enough not to cave in when the pool is empty and in the ground. This is nice and true, but I’m not sure if it’s worth the extra cost as a regular walled above ground pool goes in the ground too and usually with few issues.

VIII. Semi in-ground pool

I hear this term more and more and it’s slightly misused. First off, there really is a thing called a semi in-ground pool and that’s not at all what I’m talking about here. A real semi in-ground pool is closer to an in-ground vinyl liner pool than an above ground in price and structure. A more accurate term for what I’m discussing is a “semi in-ground above ground pool”.

The term semi in-ground is used for above ground pools that can go partially in the ground. I say this is a misused term, because all above ground pools can go partially in the ground. The fact is the only real “semi in-ground above ground” pool that I know of is the above-mentioned extruded aluminum wall pool. Interestingly, I have installed the extruded aluminum pool above the ground as much as I have installed it semi in the ground.

Nice List, Dude, but Should I Get Aluminum or Steel?

The above-mentioned types of pools have three kinds of walls – steel, aluminum, and extruded aluminum. If I’m strictly speaking of the wall itself, then I don’t see any advantage to getting the regular aluminum wall for your above ground pool. They are flimsy and are too thin to stop corrosion from eventually compromising the wall’s integrity. Regular aluminum walls are bad for installing the pool halfway in the ground too as they are not at all rigid and thus have a greater capability for a cave-in when the pool is empty.

Extruded aluminum walls are really strong and will last forever, but the price difference is really big. Unless you have enough money for it not to matter, I don’t recommend the extruded wall pool. Steel walls is my choice. Most above grounds have steel walls so you’re good there.

So, now that I have established that I prefer the wall of the pool to be steel, what about the other parts? I have had good luck with other parts of the pool being aluminum. Uprights and top rails made of aluminum seem to hold up better than steel ones for sure. I do prefer resin top rails over all others as they usually hold up better than the metal ones. I also prefer the bottom track and connectors to be made of steel too as aluminum can be too light and flimsy and resin connectors can crack.

When buying a hybrid above ground, there is almost no way to find out which parts are made of what and it may not matter much anyway. For me the best combination is for a pool to have a steel wall, steel bottom track, steel or aluminum bottom connectors, steel or aluminum top connectors, steel top stabilizer bars, steel or aluminum uprights, and resin top rails and caps.

    What are your thoughts on a 24 x 52 Mirage pool?

    1. Dan Dougher Avatar

      A “Mirage” named pool could be anything as any retailer can call any pool any name they like. If you mean the Mirage pool made by Mighty Sun, then my thoughts are negative. Mighty Sun is a Japanese manufacturer that’s been making above ground pools for a really long time. I guess Japan has long run out of recycled steel from 57 Chevys because their pool walls are super flimsy. Also, Japanese resin (plastic) parts are more brittle than US made injection molded products. Buy a pool made in North America(US or Canada). It’s worth the slightly higher price.

    IM LOOKING TO BUY A POOL THAT IS SALT WATER ,,I WAS TOLD YOU BETTER GO WITH ALUMINUM THAN STEEL HE SUGGESTED A SWIM N PLAY OXFORD,,,,,,,ANY INPUT ON THAT BRAND

    1. Dan Dougher Avatar

      Swim-n-Play makes an ok pool. There is at least one oval model they have that I won’t build because it’s engineered wrong but other than that, they are American made and not bad.

        Hi Dan – just curious as to what swim n play pool you would not recommend. We are looking into buying a 15×30 steel swim n play Cat2000. Thank you!

        1. Dan Dougher Avatar

          I’m sorry that I can’t tell which Swim-n-Play oval model I don’t like. (Cat2000 has no meaning for me) Model names can change or be different depending on who is selling them. The only indicator I can give is if the instruction manual requires a ridiculously large cove (something like 12″ high and 12″ outward) along the straight sides of the inside of the pool, then that’s the one. I know that doesn’t help much as you’ll have to get access to the assembly manual before you buy. But, it may be worth the hassle as the pool model I’m talking about will most likely lift.

        Hi, we were looking at a steel wall with resin tops pool kit from swim and play? I have read mixed reviews?

          And I have mixed opinions of them.

    Hi, Dan. I’m looking into buying a steel aboveground. Is this a good material for saltwater or would chlorine be better for longevity. In case size makes a difference, it will be a 15′ round.
    Thanks.

    1. Dan Dougher Avatar

      The walls have to be made of metal and it doesn’t matter whether you get steel or aluminum for a salt pool. You may want to get a pool with a resin frame though.

    Hi Dan
    Thank you for the great info. I have a 30 feet oval saltwater pool . The walls, top and bottom tracks are steel. It has lasted now 11 Year’s and now it is time to be replaced. I live in Richmond Virginia,so We do get some cold weather but not too bad. Because of the salt water the pool really rusted bad the last two years. We can get a steel pool for around $1700 and an aluminum pool for around $2400 . What pool would you suggest?

    1. Dan Dougher Avatar

      It’s hard to say but if the model specs, manufacturer, and quality is the same, then I would go with the steel pool.

    Hi,
    I’m looking at 12×20 oval Torino (aquasport) with extruded aluminum and resin top rail. Price is more than I expected. Other option is SwimMor steel with resin. Came in about 1k cheaper. I don’t want it to be an eye sore. Any suggestions on if the extra money is worth it for aesthetics?

    1. Dan Dougher Avatar

      I have never heard of a SwimMor so I don’t know which is better.

    Hello,
    I am looking to purchase an above ground 12 x 24 or a little larger oval saltwater pool. I was wondering what the best pool would be Structurally, I have been learning that most pool builder/ installers have their opinions of what’s best and there is a ton of differences I just want an all around awesome pool that will last. Price is not a factor I want the best so as not to have the headaches. I live in the Arizona Mountains so it is extreme hot then winter freeze we also get high winds. If you have some suggestions I would be grateful.

    Thank You,

    Evie

      Hi Evie, I have some general guidelines on what to purchase but it would be too much to write here. Please visit centralfloridaabovegroundpools.com. I wrote every word and it should help.

    Hey Dan, have you ever heard of the Medallion St. Croix Freedom Series pool. It is an aluminum bolt together panel pool. All the panels are 2′ wide and 48″ high. They clam it can be fully recessed into the ground. The aluminum is .063″ thick (14gauge). And they state that the dirt backfill can go up against the pool. What are your thought on this pool? Basically the same price as a nice above ground pool.

    1. Dan Dougher Avatar

      “Basically the same price as a nice above ground”? Yea very basic. Like they are both cost five figures. Make no mistake, those panel pools are considerably more expensive than a continuous wall above ground. As far as that particular make/model, I don’t know. I’ve never built one. They are not very common. Too expensive.

    Hi Dan, I’m thinking about getting an above ground pool but I want to sink it half way down into the ground. Should I go with galvanized or aluminum? Also what brands do you recommend?

    1. Dan Dougher Avatar

      Galvanized and just about any pool as long as it’s made in the US or Canada. Overseas pools don’t last.

    Hi 🙂 Our 27′ steel-walled 17 yr old pool (bought it at 7 yrs; owned it for 10) collapsed in a most dramatic way at a pool party last weekend, and I miss it desperately already :-/. We don’t have the money to buy a new one, but found a used 13 yr old fully aluminum one on Craigslist for $500/obo. Went to see it and it appears to be in perfect shape. Seller cut away some of the cracked liner to let us see a sample of the interior wall, which looks fine.

    One minute we’re excited to have found such a great deal–but the next we’re asking ourselves, “What–are we crazy to put money and sweat equity into such an old pool??!” I’d love to hear your opinion/suggestions.
    Thanks,
    Barbara

    1. Dan Dougher Avatar

      That’s easy. Save your money and wait to buy a new pool. It’s $500 plus you’ll need a new liner and probably at least a new skimmer/return. You’re about halfway there already. And don’t forget the “most dramatic way” your old pool collapsed.

    Any comments on Radiant Pools? Are they worth the money? Are they better than a steel frame pool?

    1. Dan Dougher Avatar

      I don’t know if Radiant pools are worth the money. It depends on your situation. They are nice though.
