ABC Supply Co., Inc.: A Pillar of Beloit’s Riverfront and Employment
Landscape
ABC Supply’s bold white building is a defining feature of Beloit’s riverfront. Perched on a hill with sweeping views of the Rock River, lagoon, and Riverside Park, the headquarters is more than just a scenic landmark, it’s the heart of a company that plays a vital role in the local and national economy.
ABC Supply Co., Inc. is the largest wholesale distributor of roofing and select exterior and interior building products in North America. With over 1,000 locations across the U.S. and Canada and more than 20,000 associates, ABC Supply is a privately held company that continues to grow and innovate. The company has earned 19 consecutive Gallup Exceptional Workplace Awards, is a two-time recipient of Glassdoor’s Employees’ Choice Award for Best Places to Work, and was recently honored with the NAW Distributors Deliver Award by the National Association of Wholesaler-Distributors for its industry leadership and community impact.
Founded in 1982 by Ken and Diane Hendricks, ABC Supply was built on a vision of hard work, smart business, and giving back. Diane Hendricks reflects, “In 1982, Ken and I had a vision. We wanted to be productive with our lives, make a difference in our industry and give back to those who helped us achieve our dreams. Ken and I were blessed to be born in this great nation, where we are born with the gift of opportunity and freedom. Our vision was to live the American dream by working hard, working smart, and having fun.” (read more about Diane Hendricks)
