In the past, steel pools dominated the aboveground pool market. There wasn't much choice for your aboveground pool outside of the size and maybe the design of your vinyl liner. But as of 2011, resin pools have become more popular with the average pool shopper. That's because a resin pool has several distinct advantages over their steel counterparts, but a few drawbacks as well.
Manufacturing and construction industries use resin because of its low maintenance and weathering capabilities. Most resin used for the manufacturing of plastics such as those on aboveground pools is a synthetic, man-made compound. Resin, both natural and synthetic, begins in the liquid state and is then hardened and cured. Some pool professionals, disagree on the effectiveness of resin as a material for swimming pool frames and railings.
To understand resin-based pools is to understand the differences over a traditional steel pool. Resin pool frames and pool walls are more sturdy and structurally sound than steel pools. They are corrosion-resistant compared with steel walls. Resin pools continue to look new because they are resistant to staining or fading from the environment. Replacing parts in a resin pool such as a railing or pool upright are relatively easier to do because there are fewer screws compared with a steel pool frame with steel railings.
Another choice when it comes to purchasing a swimming pool is to choose a steel pool wall with a resin-based railing and pool uprights. This is ideal for people who are concerned with the lack of flexibility in a resin pool wall opposed to a steel pool. The resin pool railings and uprights will keep the pool looking new and clean. Steel railings have a tendency to stain, fade and peel. The railings can become rusted, especially underneath the pool ladder base, but resin does not rust.
Steel products have give to them. They can bend and flex with the conditions of pressure and weight. Resin is a solid and hardened compound that has little flexibility. Aboveground pools with resin pool parts snap into place and do not move. If the pool parts are put under stress in any way they run the risk of cracking. Weather such as freezing or extreme heat can contribute to these risks, as well as basic swimmer use.
