What We Do

About Us:

Tate offers comprehensive industrial system solutions and field services, including a dedicated preplanning process that identifies optimal construction processes, seeks opportunities to modularize critical mechanical equipment and meets or beats project and shutdown schedules.

We were founded in 1924 by William Tate to service the Baltimore marine industry. We’ve been continually based in Baltimore and family-owned to this day, evolving with the needs of the market to expand our service to the entire Mid-Atlantic region.
