A: We build custom tanks in any diameter up to 12 feet, from compact process vessels to chassis-mounted vacuum tanks, in both carbon steel and stainless steel.
Q: What materials are used for custom tanks in California?
A: The two industry standards are carbon steel and stainless steel — the materials we work in exclusively. Carbon steel is the economical workhorse for fuel, water, and fertilizer storage (UL-142, API-620/650, AWWA D100). Stainless steel is preferred where corrosion resistance and sanitary conditions matter, such as food processing and fermentation.

A: Right here. Custom Tank Fabrication builds tanks up to 50 feet long and 12 feet in diameter: UL-142 double-wall tanks (horizontal and vertical), API-620/650 storage tanks, AWWA D100 water tanks, and vacuum/pressure tanks rated up to 150 PSIG.
Q: How are fermentation tanks fabricated in the US?
A: Fermentation tanks are engineered to spec, then stainless steel sheets are cut and rolled into shells, precision welded, polished to a sanitary interior finish, and pressure tested. At Custom Tank Fabrication in Sanger, CA, every stage — design, fabrication, finishing, and quality control — happens in-house.
