What We Do

Bear Flag Iron Works was founded by native San Franciscan iron worker and designer, Sean Santana. 

COMMERCIAL STEEL CONSTRUCTION MANAGEMENT: We offer an array of commercial steel construction services including project management, consultation, fabrication and installation. Local Bay Area projects include Academy of Sciences, Rincon Towers, 101 California Street, SF City College, Facebook Menlo Park Headquarters, San Francisco and San Jose International Airports.

Our client orders range from corporate furniture (conference room tables, benches, etc..), residential (stairways, railings, gates, etc..) to special event venue fixtures (bars, display cabinets, etc..).
