History of 3M Little Rock

3M Little Rock is one of four plants that produce product for the Industrial Minerals Products Division. The Little Rock facility supports the southern and southeastern parts of the US roofing market.

3M Little Rock has a long history in Arkansas. The plant operates in two separate sites – College Station and Arch Street. The College Station facility was originally built in 1947 to produce roofing granules for a growing roofing US market. In 1950, Big Rock Stone and Material Company was acquired to provide a stable supply of nepheline syenite, the base mineral for our roofing granules.

The mineral is an igneous rock that has physical properties desirable for roofing granules including resistance to decomposition from weather, consistent quality for the ceramic coloring process and it is opaque to ultraviolet light rays that can deteriorate the asphalt coating.
