Elegant style combines with high-tech material and an extra strong steel wall to make the Trinity the finest above-ground 52? deep pool on the market today. Designed and manufactured by one of the world?s leading pool manufacturers, this pool features their thickest (.46mm) steel wall with superior Star Galfin? galvanization to provide further rust protection. With all resin components, the Trinity is a notable improvement on the traditional pool with steel components. It incorporates unsurpassed beauty and strength in a corrosion-proof pool structure. If you want the ultimate in quality and style for your family, invest in Trinity?s premium features: HIGH TECH DESIGN AND CONSTRUCTION - Trinity pools are constructed of advanced resin and composite materials that make the structure (top& bottom rails, uprights, and bottom plates) super strong and impervious to corrosion. Potent U.V. imbedded in the resin provide additional protection against the elements. From the internal ribbing in the top seat, to the multiple layers of protective wall coating including an alloy of zinc, aluminum and rare Earth metals, this pool is designed for rugged durability and many years of family fun. As an added bonus, the beautiful injection-ed top rail and seat cap give the Trinity its designer good looks. 100% CORROSION - The Trinity?s top and bottom rails, uprights and connecting plates are made of entirely non-corroding resin. Neither mid-summer sun nor driving rain and ice can cause these parts to corrode as they can with a steel pool. Because resin is non-corroding by its very nature, there are no coatings to apply that can eventually chip, crack, or fail. Our Trinity pool gives you the designer beauty that resin affords, plus the added benefit of a corrosion-proof structure that will outlast any steel pool available. TRUE ROUND DESIGN ? The top rail on round sizes is a ?true? round, giving the Trinity a graceful look . No more ?stop sign? appearance from straight-edge toprail.
