Electronics Manufacturer

I can remember 8 years ago when we decided to order goods from STR Industries for the first time. STR not only saved us money but cleared a way for reducing our overhead and the transition was seamless. I could not imagine running our business without them. By STR concentrating on the back end functions, we were able to concentrate building and expanding our business.

Bearing Manufacturer

In these tough economic times, we needed to make changes in our operation as we were not utilizing our building or staff to their fullest. STR was able to create a cost effective and efficient supply chain model for our company. People at STR have been very flexible as they are able to adjust quickly to our customer's needs. With the integration of our systems and the ability to view all real time data via online web portal was just another factor that sealed the deal with STR.
