Field tested under a variety of conditions
RHINO MANHOLES have been field tested under a variety of conditions to meet exacting design and quality standards for long life and corrosion resistance installation. They have been proven to outlast concrete, steel, and fiberglass manholes.
Using 100% virgin polyethylene plastic, our industrial strength plastic manhole unit offers a wide range of chemical resistance to acids and many organic compounds. Because of this resistance, attack from hydrogen sulfide, sulfuric acid and other aggressive chemicals does not occur.
