CRANBERRY TWP — PPG Industries will establish a new architectural coatings headquarters that will bring up to 500 jobs to the Cranberry Woods office park off Route 228.

Bryan Iams, vice president of corporate and government affairs, said Monday the initial transition to Butler County is scheduled to take 12 to 18 months. But there’s no deadline to complete the process.

“And as the business continues to grow and assess its resource needs, it will generate additional job opportunities,” Iams said.

The North American Architectural Coatings part of PPG’s business includes well known consumer paint brands such as Gliddon, Olympic and Pittsburgh Paints.

Those people who will relocate to Cranberry are management for the architectural coatings business, administration, finance, customer sales and support. Nothing will be made at that site, and the global headquarters for PPG will remain in Pittsburgh.

All of the jobs that will relocate to Cranberry already exist within the company. However, about 240 of them will be relocated from these communities: Louisville, Ky., Dover, Del., and Strongsville, Ohio.

The 120,000-square-foot headquarters will be in Cranberry Woods’ building four, which was previously occupied by Westinghouse Electric before its office consolidation in 2012.

Iams said PPG picked the site because it is between the company’s key sites in Ohio and southwestern Pennsylvania, including Gibsonia, Allison Park and Harmar.

“Cranberry sits in the middle,” Iams said. “This will be PPG’s very first site in that area.”

PPG joins major companies such as Westinghouse, MSA, Danieli Corp., Verizon Wireless and McKesson Automation that call Cranberry Woods home.

“The selection of Cranberry Township and the Cranberry Woods Business Park continues to validate our business friendly environment and the desirability of Cranberry Woods,” said township manager Jerry Andree.

“PPG joins an impressive group of companies in Cranberry Township that offer family sustaining jobs, a primary goal of the Cranberry Plan.”

Ken Raybuck, executive director of the Community Development Corporation of Butler County, said, “We are excited with PPG’s decision to retain jobs in the region and bring many additional employees to their new division home in Cranberry Township.”

At the same time as the Cranberry move, PPG plans to expand its existing technology center in Harmar Township, Allegheny County, which will bring another 60 jobs from out-of-state to the region.

The technology center includes PPG’s glass and fiberglass business and research and development activities.

“Our plans to establish a central headquarters and R & D center for the company’s North American architectural coatings business in Pennsylvania are an important step in creating our newly expanded coatings business,” said Charles E. Bunch, PPG chairman and CEO, in a news release.

“PPG has called Pennsylvania home to its global headquarters for 130 years, and this further strengthens our presence in the state and affected counties.”

According to a written statement from the office of Gov. Tom Corbett, PPG received funds from the state Department of Community and Economic Development, including a $1.25 million Pennsylvania First Program grant, $618,000 in Job Creation Tax Credits and a $42,750 Guaranteed Free Training grant that will train its new workforce.

A $2 million loan from the Pennsylvania Industrial Development Authority to be repaid within 15 years also was included.

In all, the two moves bring 300 jobs to Pennsylvania.

Corbett said, “Today is a win for southwestern Pennsylvania, proving that the best way to spur new job growth is to work with local leaders and businesses.”
