Established in 1948 in San Carlos, Calstone has four manufacturing facilities in operation, Sunnyvale, Galt, San Martin, and Tracy. These centralized manufacturing locations enable us to provide services to much of the state, going as far north as Eureka, and far South as Fresno, and as far East as Reno on a regular basis.

Calstone has highly qualified customer services and sales representatives that are on call to answer any questions you may have. Management is always readily available to answer any of your questions, one of the many distinct trademarks that has set the company apart from others throughout our 60 year plus history.
