This product features a cylindrical design, with the cylinder made of high-strength glass fiber composite material. Both ends are designed with wheel-type concave and convex surfaces, offering high compressive strength and load-bearing capacity, as well as resistance to corrosion and acidity/alkalinity. Under normal use, its lifespan exceeds 50 years. The pool is fully formed using a monolithic technique, ensuring no seams, excellent tightness, and no leaks. The product is available in both standard resin and flame-retardant resin types, with quick and easy installation, resulting in a short construction period.
