GROCO

GROCO (Gross Mechanical Laboratories, Inc.) was born in the basement of a Baltimore row house in (approximately) 1918, with a pair of workers trained personally by founder Angus Roy Gross, Sr.  This was a time when the entrepreneurial spirit flourished in America and when the industrial boom stood on the shoulders of an expanding steel industry and quickly growing automotive and marine industries. 

In addition, as the times progress GROCO continues right along with them. From humble yet storied beginnings GROCO has looked to the future to stay on the cutting edge of product development and technology. From manual machining generations ago to the latest in CNC technology GROCO continues to develop in order to provide the market with the best products in the industry.

Today, as GROCO’s over 100 years later, GROCO continues the tradition of innovative design and unsurpassed quality.
