What Olson & Co. Steel, Inc. does

Olson & Co. Steel, Inc. (d/b/a Olson Steel) is a privately held, vertically integrated steel fabrication and erection subcontractor founded in 1960 and headquartered in San Leandro, California. The company operates two fabrication facilities — a 150,000-square-foot San Leandro plant with four acres of yard capacity and a 10-acre Fresno plant operating since 1970 (AISC and City of LA certified) — plus a Southern California regional sales office in Los Angeles. Headcount is reported in the 251–500 range. Core services include structural steel fabrication, field erection, BIM modeling and in-house detailing (with 15–20 detailers centrally located across San Leandro and Fresno), seismic retrofits, architectural/ornamental metals, steel stairs, miscellaneous metals, and emerging mass-timber/CLT hybrid construction. Technology stack centers on Revit, Tekla, AutoCAD, Pronest, and direct CNC integration for fabrication, with FABTROL estimating software and SAGE Timberline ERP integrated into daily operations.

The company serves as a subcontractor to general contractors on commercial, institutional, healthcare, government, education, transportation, entertainment, and retail construction projects across Northern and Southern California. Revenue is generated through project-based competitive bidding on construction RFPs, with long-standing GC relationships including Turner Construction, Hathaway Dinwiddie, Whiting-Turner, DPR Construction, Devcon Construction, and C.W. Driver. Notable project portfolio includes Salesforce Tower (miscellaneous metals on the 1,070-foot tallest building in the western U.S.), San Francisco City Hall seismic retrofit (world's largest base-isolated building at $300M project value), Stanford Bing Concert Hall, Mills Peninsula Hospital, Kaiser San Leandro Hospital, Oakland Airport BART Connector, Netflix Los Gatos Gateway, and SF Giants Stadium ornamental steel. Go-to-market relies on general contractor relationships and project reputation rather than traditional marketing channels.
