Product Description
CYLINDRICAL OPEN TOP TANKS
Tanks are manufactured in one piece, seamless construction and liquid tight. Made of 100% 1st grade Linear Polyethylene (LMDPE) resin, they will not rust or corrode and are nearly indestructible. They are designed for either indoor or outdoor application and conforming to ASTM D 1998-97 Designed Standards for liquid storage. All are efficiently lightweight for easy transportation and installation. They possess excellent low temperature impact resistance and are U.V. stabilized. These tough, heavy walled tanks are designed for normal and heavy-duty industrial applications, ideally for bulk water and chemical storage (resistant to most chemicals-technical data available upon request). Excellent Environmental Stress Crack Resistance (ESCR) and provide durability under severe conditions.
