Calcinor Expands into the U.S. with the Establishment of Kelsen Refractories USA Inc.

Calcinor, a well-established company in the industrial minerals and refractory industry, continues its strategic growth with the expansion into the U.S. market through the launch of Kelsen Refractories USA Inc. following the acquisition of a refractory plant in Tarentum, Pennsylvania.
This marks a significant milestone for the company as it strengthens its international presence and reinforces its commitment to the refractory sector in North America.

The decision to establish operations in Tarentum, near Pittsburgh—also known as ‘The Steel City’—is a strategic one. The region’s rich industrial history, strong manufacturing infrastructure, and well-connected transportation network make it an ideal location for refractory production. Its proximity to key steel industry players further enhances the strategic advantage, allowing for efficient supply chain management and collaboration within the sector.
A Strategic Expansion into the U.S. Market
This move represents a natural progression in Calcinor’s long-term vision, expanding beyond its traditional markets and deepening its engagement with the North American industry. Previously serving the U.S. market through exports, this direct presence enables Calcinor to better serve customers, optimize logistics, and leverage local resources to enhance efficiency and sustainability.
Kelsen Refractories USA Inc. specializes in the production of dolomitic refractories, both unshaped and shaped (tempered-DGU and fired-DGG). With the backing of Calcinor’s extensive expertise and technological capabilities, the facility in Tarentum is set to become a key player in the region, ensuring high-quality production standards and innovation.
Strengthening Our Team for Future Success
This expansion integrates a highly skilled American workforce with the expertise of Kelsen’s European specialists. “We warmly welcome our new colleagues in Tarentum to the Calcinor family. Their knowledge and dedication will be invaluable as we embark on this new chapter together. Our combined efforts will strengthen our position in the market and drive continued innovation.” said a company spokesperson. The newly formed team will collaborate closely to implement advanced production techniques and ensure operational excellence.
Commitment to Innovation and Industry Leadership
“Entering the U.S. market is an important step in Calcinor’s growth strategy,” said a company spokesperson. “With the establishment of Kelsen Refractories USA Inc., we are not only expanding our footprint but also reinforcing our dedication to excellence, sustainability, and customer service.”
The integration of this facility aligns with Calcinor’s long-term vision of driving industrial innovation while strengthening its presence in key international markets. Through ongoing investment and collaboration, the company remains committed to delivering high-quality refractory solutions that meet the evolving needs of the industry.
