Products & Services


Our primary business is the manufacture of roofing granules – rock which is crushed and colored to make asphalt shingles. We sell to the most shingle manufacturers in the United States.

All the products we sell are crushed to a range of sizes. The granules are then treated with an opaque ceramic coating and other chemicals that provide functionality and beauty.

*Not all colors are available at each Industrial Mineral Products Plant.
