Agriculture Tanks

Design Tanks builds low-maintenance, durable fiberglass agriculture tanks that are built to hold bulk fertilizers, soil fumigants, herbicides, and even water while providing long-term performance and maximum resistance against corrosion and chemical attack. Vinyl ester liners can be added for enhanced protection against more aggressive fertilizers. The standard agriculture tank design provides easy access to the tank interior for inspection and maintenance.

Available in a range of sizes and colors, the Design Tanks agriculture models give a tank life of over 20 years with no external maintenance expense because of their integral pigmented exterior. In addition, easy-to-install agriculture tanks are 75% lighter than steel while providing a higher strength-to-weight ratio, and will not conduct electricity.
