About us

GranQuartz was initially founded in 1971 in Tucker, GA by Peter de Kok. Much earlier than this, his father owned quarries in South Africa and immigrated to the United Kingdomimage_PeterDeKok2 in 1957, de Kok was only 17 years old at the time. Around the age of 19 years old, he began selling stone for his father’s company. His father’s business traded in rock from places such as South Africa, India, Brazil, Sweden and Norway. While working in the U.K., de Kok began coming over to Canada and market stone here. In the early ’60, he started selling in the United States. De Kok’s product was mostly used in the monument industry. In September of 1970, de Kok moved along with his family to the United States, in Atlanta, GA, which was close to Elberton, the biggest monument working location in America.

De Kok spent a few years running the American arm of his father’s company, which was called Granite and Quartzite Center. Disputes over the management of the company with equity partners led him to depart and start his own business. He didn’t want to compete with his old outfit, so he focussed on selling tools and equipment rather than rock. GranQuartz Stone Tools and Equipment started out importing and exporting products such as roofing nails, shingles, and machinery. Eventually de Kok began marketing tools and equipment needed for stone fabrication.

At this time, GranQuartz, located in Beebe was doing mostly larger blades for cutting blocks for the monument and building trade. At this point, Alain Bedard had become General Manager of the Beebe location. In 1993, the location in Beebe, QC separated from its mother company GranQuartz L.P. becoming GranQuartz Canada. This transaction was done to help GranQuartz Canada better serve their customers.

In 2008, while Mr. Peter de Kok, leaving for retirement, sold his company, GranQuartz L.P. to the Harbour Group. GranQuartz Canada and GranQuartz L.P. remain two privately owned and completely independent companies that serve their respective territories while being the leaders in their fields.
