Our Customers Say:

“I wanted to take the time to personally thank you for the time and effort that LTI has put into the testing involved with our orders. Your staff has been invaluable over the last several years.  Additionally, the fact that you are now able to perform Fracture Toughness testing in house has already proven priceless in both the turnaround time and in getting my questions answered. I’ve been fortunate to have worked with LTI since 1986 and I have come to think of LTI as an extension of Dubose. I look forward to our continued relationship.”
