Specialty Granules Snapshot
We provide innovative roofing, aggregate, and agricultural solutions, prioritizing safety, employee engagement, and environmental sustainability while forging strong partnerships with customers to understand their evolving needs.
Specialty Granules LLC has been a leader and innovator in aggregates and mining for over 100 years, manufacturing specialized products for the roofing, construction, and agricultural industries.
SGI is headquartered in Hagerstown, MD, and has six plants strategically located across the U.S. Plants in Blue Ridge Summit, PA; Annapolis, MO; Pembine, WI; Trona, CA; 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 help protect 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.
In each of the communities we are located, SGI is the premier place to work. Our employees enjoy our strong emphasis on safety, our positive work environment, competitive wages & benefits, & our long term stability.
As a Standard Industries company, we leverage the reach and reputation of a privately held, forward-thinking global industrial company focused on innovation.
The Standard ecosystem spans a broad array of holdings, technologies, and investments—including both public and private companies from early to late-stage—as well as world-class building solutions, performance materials, logistics, real estate, and next-generation solar technology.
