Power Steel� 14' x 48"/4.27m x 1.22m Pool Set - Water Capacity (90%): 15,232 L (4,024 gal.) The round shape of the pool provides for easy installation, enhanced stability, and less wasted space due to the fact that the pool doesn�t require lateral support. The extra strong side walls of this pool are constructed with Tritech�, a 3 layer reinforced material with a polyester mesh core encased between two layers of high gauge PVC material. This creates a total thickness of 0.40-0.80mm (16-32 gauge) depending on the size of the pool, offering superior strength and durability
