ROC Carbon Company Overview
For Over 65 Years,
ROC Carbon has provided high quality products and responsive service to help meet our customer’s needs.
Recently, we have initiated a program that expands our long history of offering urgent next day delivery of custom parts, to all orders. This initiative required many changes in all departments as well as a new, live order tracking system.
As our industry changes, ROC is working toward leveraging web based tools to better serve our customers. We redesigned our website, added web blogs, and a new chat service to make communication with prospects and customers more flexible and engaging. I encourage you to experience these new services. Also, with artificial intelligence gaining momentum, ROC is beginning to study how this tool can be used to serve customers faster and provide better solutions.
These changes are allowing ROC to improve upon the core elements that we have always provided: responsive service, custom parts, and technical assistance.
