Rockville Fuel & Feed Co. - Rockville Fuel & Feed was founded in 1926 in Rockville, MD. At the time, Rockville was a sleepy agricultural town along the railroad tracks in Montgomery County. The original business model of the company was to deliver wood and coal to Montgomery County residents to heat their homes and sell feed and straw to county farmers for their livestock. That's where the name comes from.

In the mid-1930's, the company added the production and distribution of cinder blocks to its business model. And in 1950, Rockville Fuel & Feed got into the concrete business through a business arrangement with Contee Sand and Gravel. Contee was looking for a site to put a concrete plant in Rockville to supply concrete for a local road construction job. Rockville was willing to allow Contee to set up a plant at the company location on Hungerford Drive. At the end of the job, Rockville bought the plant from Contee and was in the concrete business.

Zimmerman Industries - This Associate member and member of the Volumetric Mixer Manufacturers Bureau began in the early 60’s when Pennsylvania farmer and inventor Harold Zimmerman saw the need to deliver fresh batched concrete on site. He determined that the only way to do this was to combine the batching, mixing and delivery operation into a single machine. In 1964, after several years of research and development, Zimmerman applied for a patent on his newly designed concrete mixer and in March 1967 the patent was granted.

More than half a century later, Zimmerman Industries delivers units to all segments of the concrete industry and to all corners of the world, including South America, Africa, Seoul, South Korea and throughout the U.S. Read more.
