Food & Dairy Tank Fabrication

SFI has been working with the food and dairy industry since opening in 1985. We build a variety of stainless steel tanks and processing equipment for our food and dairy customers and everything we construct is custom designed and fabricated to meet your individual needs.

Tanks and vessels for food and dairy service can be built in our shop or on-site in the field. We build tanks of all sizes from small processing vessels to storage tanks in excess of 600,000 gallons. These tanks can be polished inside and out making them sanitary and easy to clean. SFI tanks can be included in aseptic production lines, maintaining sterility from processing through packaging. Gaskets from FDA approved materials are also common. Various levels of documentation are available.
