​Long before our ISO 9001:2015 registration, SSI understood the importance of quality and reliability.

Our PPQ (People Performance Quality) Program that had been in place for many years made the certification process relatively easy.  Since 1998, SSI has maintained our commitment to ISO 9001 and currently has an ISO 9001:2015 registered status.


​The safety of our employees and customers is a primary focus at SSI.  Our commitment to safety and diligent adherence to safe practices in our shops and at our job sites is evidenced by our impressive safety records.
