A Global Refractory Leader

HWI is the largest supplier of refractory products and services in the United States with a history that spans more than 150 years. Acquired in February 2023 by Platinum Equity, it is now part of Calderys, being the brand for the Americas region of the Group. HWI counts 19 manufacturing sites and 22 distribution centers in the Americas, as well as the largest refractory industry research facility in North America. Serving virtually every major industry that requires refractory solutions to enhance production and protect assets, HWI is consistently recognized for its talented experts, industry firsts, and intensely driven excellence.

Refractories: A Vital Industry

With roots as old as the discovery of fire, refractory is the backbone for virtually all other industries that manufacture in extreme environments. Virtually all major industry sectors — glass, steel, aluminum, petrochemicals, chemicals, and more — rely on refractory products and services to protect their assets in production. And as the refractory industry continues to become more technologically sophisticated, you’ll find challenging and rewarding career opportunities in a viable and stable industry that’s vital to American and global manufacturing.
