3M has a rich history in manufacturing and mining, starting in 1902. The 3M Industrial Mineral Products Division is part of that heritage; producing quality granules for the roofing industry for over 85 years. Using 3M science in processing, coating, and adhesives technologies allows us to improve the performance and durability of our granules, giving manufacturers a better product that will stand the test of time.
3M quality granules are dense, non-porous, UV ray resistant and tough enough to stand up under handling. With a proprietary ceramic color coating and surface treatment, 3M granules reduce color variability of the shingle and reduce asphaltic staining from bundles in storage.
3M offers three distinct types of roofing granules: Classic, Cool, and Copper:
3M Industrial Mineral Products has four plants conveniently located across the United States to better serve our manufacturing customers. Our plants support both bulk rail and bulk truck shipping, with super sack bagging at some locations for smaller quantities.
In this video Randy Morgan, National Accounts Manager for Industrial Minerals, takes us on a tour through the 3M Roofing Innovation Center where we help manufacturers develop and test shingle color blends.
This process allows manufacturers to easily see what a color would look like on a roof. Taking a mere 20-30 minutes for the center to complete; manufacturers benefit from quick, simple and realistic color examples without tying up their own production lines for testing.
