About Us

Your RESource for Cast Plaques and Prototypes

South Bay Bronze originated as an old and respected foundry in San Francisco, CA, that had been in operation since 1846. Formerly known as Kingwell Bros, Ltd., the foundry was repurposed by the current owner, Gil Hernandez, to meet the growing needs of the industrial, military, and metropolitan communities.

As a full-service foundry, we offer a range of metalworking solutions, including cast plaques and prototypes. Many industries rely on our facilities to meet their manufacturing and sculpting needs.
