Not All Metal Tanks are Created Equally

Most metal water tanks are imported into the US and their steel is sourced from foreign countries that do not comply with US standards.

Premium Materials are Our Standard

All CorGal water storage tanks are engineered to these minimum standards:

G-115 hot dipped galvanization
20-gauge steel sidewalls
24-gauge steel roof panels
Designated bottom wall sheets to better distribute weight
Full tank geotextile preliner
24 mil PVC flexible membrane liner
Schedule 80 PVC flanges or hot-dipped galvanized steel flanges

Tanks Engineered Site-Specific

We offer a thorough, site-specific structural design calculation package (SDCP), stamped by a professional engineer licensed in the project location state. This ensures each tank is built to the location’s specific requirements and complies with local ordinances and laws, protecting all parties. Site-specific tanks may incorporate thicker metal wall sheets or roof panels, stiffeners, heavy-duty anchors, and other components to satisfy the local seismic, wind speed, and live load requirements.

We take engineering very seriously for the safety and security of all parties involved.

Our Steel

We are proud to say that CorGal Water Storage Tanks have always been made from 100% AMERICAN milled and fabricated Class 1 Structural Steel. Our tanks are offered with a 30-year structural warranty – the longest in the industry.
