With a legacy of professional quality and service dating back to 1955, ACG Materials has earned the industry respect of our customers from the smallest organizations to Fortune 500 companies. We are dedicated to providing the expertise that only experience brings. ACG Materials is the result of a long and successful history of doing one thing and one thing only. Treating people right. Our customers, our employees, our partners, and vendors. We believe when you take care of the people that matter most, everything else will take care of itself. ACG Materials roots go back to 1955 when the Harrison Gypsum Company originally began as a small family operation supplying gypsum to the family farm and neighbors. Originally named the Cement Gypsum Company, Harrison Mine No. 1 was opened near Cement, OK, and underwent the name change to Harrison Gypsum Company in 1956. Over the years the company developed the mining business by supplying raw gypsum rock to nearby manufacturers of Portland cement. As the market area for Harrison Gypsum expanded, gypsum reserves and production capacity also expanded. With business growing, capital investments were made to upgrade to modern mining equipment and improve infrastructure. In 1994, Harrison Gypsum’s mine #2 was named the largest single gypsum mine in the United States by the U.S. Department of the Interior Publication. Today, the total gypsum reserves of Harrison Gypsum Company is estimated to be in excess of a quarter of a billion tons. Product Expansion Although the sophistication of the operation has grown over the years, the set of principles that established Harrison Gypsum as a trusted name in the industry are still in practice today. We take pride in offering flexible responsive service to our customers, while also maintaining consistent quality standards that produce a premium product. This also led to an expansion in innovation, and as the product lines grew, other companies like Allied Custom Gypsum and ACG Plasterworks were created. Growth occurred both organically with our existing product lines and through acquisition. Research and development created new custom products and a series of ground gypsum products, such as flame retardant fillers, animal feed additives, agricultural and turf products, and a high purity food and pharmaceutical grade gypsum. Our company’s mines, mills, processing plants, packaging facilities, warehouses, and 60 years of experience all attribute to our one primary objective. And that is service to our valued customer. In 2012, HIG Capital, a leading global private equity investment firm, completed a recapitalization of Harrison Gypsum. This provides Harrison Gypsum with financial and operating resources that enables us to further capitalize on our significant growth potential. In January 2015 JA Jack Ltd, a limestone producer based in Seattle WA specializing in high-quality limestone products (grits, flours etc.) joined the group. JA Jack sources their limestone from extensive high-quality company owned reserves on Texada Island in British Columbia.
