Specialty Granules Inc. Details
Specialty Granules LLC has been a leader and innovator in aggregates and mining for close to 100 years, manufacturing specialized products for the roofing, construction, and agricultural industries. SGI is headquartered in Hagerstown, MD, and has five plants strategically located across the U.S. Plants in Blue Ridge Summit, PA; Annapolis, MO; Pembine, WI; and Ione, CA, are open-pit quarries, mining rock that is crushed and screened to produce granules and aggregates. Granules are colored with ceramic pigments and utilized as colored roofing granules or left uncolored and used on the unexposed portion of shingles. These granules are then sold to roofing manufacturers in the U.S. to helpprotect millions of North-American homes each year. Rocks unable to be used for granules are instead utilized in the aggregates market to help protect roads and provide a safeguard against erosion.SGI's newest plant, located in Waynesboro, PA, repurposes rock "fines" — a byproduct of the granule manufacturing process — to create products used in agriculture to help increase crop yield.
