About Us
Headquartered in Portland, Oregon, ESCO Corporation is an independent developer and manufacturer of highly engineered wear parts and replacement products used in mining, infrastructure development, oil and gas, and industrial applications.

Product Innovation

We have focused on product innovation throughout our 100-year history. We believe our expertise in metallurgy, tribology (the science of wear), design engineering, manufacturing processes, and distribution are our core competencies. We have three divisions Mining, Construction & Industrial, and Ulterra. 

Metallurgical & Manufacturing Leaders

ESCO pioneered many foundry practices, casting techniques and steel alloys – all industry standards today. ESCO was the world’s first foundry to use Argon-Oxygen Decarburization (AOD), an advanced steel purifying process. Our design facilities are computer linked to our manufacturing facilities, and the ESCO CAD system is integrated with a sophisticated CAM (Computer Aided Manufacturing) system. ESCO computer-design stations transfer customer specifications directly to pattern making facilities, ensuring that products are manufactured precisely as designed.
