Trinity 21' round above ground pools are the perfect marriage of steel and resin materials. The 7" top rails and 7" uprights give the pool plenty of strength while keeping the components relatively cool to the touch. Paired with resin top and bottom plates, it's the perfect marriage of resin and steel.
The Trinity was designed by one of the world’s leading pool manufacturers and this pool features their thickest galvanized steel wall for the most in durability. The ultraviolet inhibitors which are embedded in the resin provide additional protection against the elements. From the injection-molded top rails and seat caps to the multiple layers of protective wall coating, including an alloy of zinc and aluminum, this pool is designed for rugged durability and many years of family fun.
On all Trinity round pools, the top rail is a true-round for a graceful look. Oval sizes feature a buttress-free design.
