Pittsburgh, PA, USA – December 19, 2023 – In less than a year – under new ownership and combining with Calderys – HWI, A member of Calderys, is fulfilling its commitment to invest in its operations with consequential upgrades at numerous North American manufacturing facilities. Additional investment projects are planned for 2024.

Investments across the Americas reinforce Calderys Group’s global competitiveness and demonstrate the company’s plans for continued advancements.

Michel Cornelissen, President and CEO of Calderys, said, “Our investments in the Americas underscore the value we place in our deep, longtime relationships with customers in the region, particularly with our many steel industry partnerships. These investments demonstrate our plans for continued growth and our leadership as a combined organization.”

Ross Wilkin, Calderys Senior Vice President of Americas, added, “In less than a year under new ownership and since combining with Calderys, we’ve successfully integrated our Americas operations with the former Calderys operations in the US and in Brazil, enhanced our products and services portfolio for customers, and completed massive investments in our manufacturing facilities. We are well-positioned for the future.”

HWI’s North American investments help to support customers’ growth and energy transition needs by elevating capacity, product quality, and innovation.

Upgrades in 2023 include:

  • Completion of Overall Equipment Effectiveness Initiative (OEE) production software upgrades across HWI’s highest volume plants: Alabama1; South Point, Ohio; Vandalia and Fulton, Missouri; White Cloud, Michigan; and Windham, Ohio.
