Yes, there are special requirements for using aluminum profiles in swimming pools and spas. These include corrosion resistance to withstand chlorinated water, which is common in pools and spas. Profiles must be made of marine-grade aluminum to prevent rust and ensure longevity. They should also be able to withstand high humidity and temperature fluctuations. Additionally, profiles need to be non-slip and easy to clean to maintain safety and hygiene. The design should also consider structural integrity to support the weight of the pool or spa structure and any associated equipment.
