About Us

SGS is a professional corporation specializing in the engineering, design, installation, and testing of low-impedance electrolytic grounding systems for commercial and industrial applications in new or existing facilities. We work very closely with specifying engineers, electrical contractors, as well as end-users nationwide to assist them with their electrical requirements from concept through construction.

Our highly trained technicians test and inspect equipment in accordance with the job specifications, NETA (National Electrical Testing Association) and IEEE standards. These guidelines are established to offer assurance to our customers that the highest level of engineering practice is followed. All of our instruments are calibrated to NETA’s specifications and the National Institute of Science and Technology (NIST) standards.
