About GMI

GMI Composites, Inc. was established in 1923 as George Morrell Industries. The primary focus was the manufacture of buttons and supplies for the garment industry in Chicago.

During the 1960's emphasis transitioned to emerging composite technologies; an early example of GMI's advanced composite work can be found in the "Bowden Bicycle". The Bowden bicycle is the forerunner of modern composite bikes - currently it is displayed in the Smithsonian Institute and the Museum of Science and Industry.

The current management group gained control of the company in 1984. Experience in advanced composites, new ideas, and innovative products followed.

GMI made its first fiberglass reinforced composite manhole cover more than 20 years ago - these initial covers are still performing exceptionally in the field today. Through continued innovation GMI has made a variety of unique underground access covers including:

• A 72 inch round H-20 rated cover that weighed less than 65 lbs.
• A replacement to a concrete trench cover that measured 29 in. by 60 in. and had a thickness of 7 in. This cover weighed less than 90 lbs. and supported more than 100,000 lbs.

GMI Composites Inc. is located in Muskegon Michigan, and all products are MADE IN THE USA.
