Attleboro-based Stergis Commercial Realty LLC, the real estate holding company for Stergis Aluminum Products Inc., will use more than $1.2 million in MassDevelopment Loans to help renovate and clean up the site of a former metal stamping and coin mint in the town.

MassDevelopment has provided two loans to Stergis – $792,000 from the agency’s general fund and $500,000 from the Brownfields Redevelopment Fund. Stergis will use brownfields loan proceeds to clean up 79 Walton St., which housed the former mint. General fund loan proceeds will help the company renovate the building at the same address, which has almost 129,000 square feet of manufacturing space, according to a statement. The company said it expects to create 48 jobs as a result of the project.

Stergis Aluminum, which has operated in Massachusetts since 1962, purchased the building after outgrowing its former Walpole site. The expanded manufacturing space will allow Stergis to turn on more fabrication lines, quadruple inventory space, and stock hundreds of standard-size windows and doors, the company said. The facility will also have a test lab, a laminated glass area and an expanded tool and die shop.

"The Brownfields Redevelopment Fund is a proven economic development tool, creating jobs and cleaning up a key site in Attleboro," said MassDevelopment President and CEO Marty Jones. "MassDevelopment is pleased to back Stergis Aluminum as it expands its manufacturing business and creates nearly 50 jobs in production and inventory."
