Only Alpha Pool Products makes its inground pool building materials in the USA. As an authorized Only Alpha dealer, we build only with Only Alpha structures. For inground pool installation around Toledo and SE Michigan, we build two kinds of Only Alpha pools: the liner-free Alpha Evolution system and standard vinyl liner kits.
Alpha Evolution pools pair Only Alpha's patented fiber-reinforced composite wall system with a concrete floor. The result is a high-end pool with no vinyl liner, for homes or commercial sites. The frame is 100% corrosion- and rust-proof. We finish our Evolution builds with an ecoFINISH coating.

SPERT is self-piercing riveting, the same joining method high-end automakers use. Alpha Advantage Shield is a clear coat applied over galvanized steel to add corrosion resistance. Only Alpha provides a lifetime warranty against SPERT failure and an unlimited transferable lifetime warranty on FUZION 5010 and Structural Armor components. Manufacturer warranty terms apply.
Only Fuzion and Structural Armor boast a patent protected formulation that confers super-strength to the pool wall. Composites like this are used in demanding aerospace and automotive applications, including by NASA, Boeing and Toyota.
