    Polymer vs Steel Inground Pool

    Polymer vs Steel Inground Pool InstallationThis is one of the most common questions we get asked. 

    Polymer vs Steel Inground Pool, which is better?  

    When we compare both systems we need to remember that everything else is the same. The pool equipment, the accessories, the possible acrylic steps and benches and the vinyl liner. Both products offer limited lifetime warranties and both are expected to last for longer than we can expect to be around.

    But there are a few differences and each one does have some advantages and disadvantages. Let’s take a look.

    Steel Wall Pool Advantages:

    • Corrosion resistance: The type of steel wall used by Campbell Pools is a 14 gauge galvanized steel using a G235 coating (or Z700 using the metric system).  This is the heaviest coating weight to galvanize steel and should resist corrosion once buried for over 50 years.
    • Steel walls are much stronger than the polymer equivalent.  Which makes sense; after all they build skyscrapers and bridges out of steel and not polymer.
    • Steel walls are easier to adjust during the installation and this makes it easier to ensure the pool wall is straight and level.
    • There is a much greater variety of panel length and radius’s available giving greater options in design, acrylic step and bench placement and coping options.
    • Steel walls also have a larger thermal range (deal better with extreme cold and hot weather) and deal better with shifting soil conditions.
    • Very wide range of possible custom step and bench designs possible using our Vinyl over Steel system. 

    Steel Wall Pool Disadvantages:

    • Steel panels are much heavier and thus harder to handle.
    • The G235 or Z700 galvanization should not corrode, but years after installation it is possible to have slight surface corrosion.

    Polymer Wall Pool Advantages:

    • Built from non-corrosive resin material, can not and will never corrode.
    • Fast to assemble and lighter to handle, prefered by many installers who will recommend because they save on labor cost.

    Polymer Wall Pool disadvantages:

    • Slightly more expensive than steel.
    • Less design options and more panels required to achieve certain designs which means a higher cost of material when compared to steel.
    • Limited to using acrylic or fiberglass inserted steps and benches.

    So at the end of the day which one is better between Polymer vs Steel Inground Pool?

    Well the answer is both. Campbell Pools sells and installs both so it comes down to our customers preference.  We can however point to the fact that every inground swimming pool that has been built for our staff over the years has been steel.

    In the end, both types of walls can fail under extreme conditions. Polymer might work a bit better in really really wet soil conditions or installed near the ocean with it’s high salt content in the air.  Steel will do better in areas with shifting soils because of it’s greater flexibility. But really for virtually every homeowner, they will never notice a difference. 

    Whichever is used, it’s the right choice.
