Mr. Bob Gallagher Retired on May 22nd!

Bob had run our Refractory Department for the last 8 years. May God Bless him with a long Happy Retirement!


Mr. Bob Norlock has been with us for the last month – (Training, under Bobby G’s Guidance!)
Mr. Norlock has extensive experience in the Refractory Business. We welcome Mr. Norlock as our new Refractory Division Manager!

As of this writing, the State of Illinois is still technically closed. Our Company, being considered an “Essential Business”, has remained open throughout the duration of this pandemic – to Service Our Client’s needs. For Emergency Service, Piping Repairs, Refractory Repairs, and Boiler Repairs……We are here for you!

Let’s pray that this all ends soon & we can get back to our normal ways of life!

Stay Safe & Healthy!
