Radiant HVAC maker Uponor Inc. marked the fifth expansion to its 230,000-square-foot corporate headquarters and manufacturing facility in Apple Valley, Minn., with a ceremony Nov. 25, 2013.

On hand for the festivities were U.S. Sen. Amy Klobuchar (D-Minn.); U.S. Rep. John Kline (R-Minn.); Sara Silvernail, deputy state director for Sen. Al Franken (D-Minn.); Republican Minnesota state Reps. Anna Wills and Tara Mack; Apple Valley Mayor Mary Hamann-Roland; Apple Valley Chamber President Ed Kearney; and members of the Apple Valley City Council and Apple Valley Chamber of Commerce.

In her remarks, Klobuchar mentioned Uponor’s recognition as a Top 100 Workplace by the Minneapolis Star Tribune and the 2013 Manufacturer of the Year by the Manufacturers Alliance.

“Supporting a strong manufacturing sector is critical to the future health of our economy,” she said. “This is about bringing our country back to those brass tacks of innovation and progress, and Uponor is already leading the way.”

The plant expansion, which added 17,500 square feet of manufacturing space and 3,000 square feet for employee services, helped the company increase its workforce in the past year by 25 percent, company officials said. Uponor now has more than 500 workers in North America.

“This expansion affirms our brand ideals of connecting, building and inspiring,” said Uponor North America President Bill Gray. “We’re not just trying to turn a profit here; we have a longer-term sustainability commitment to our company and the community.”
