About Sterling-ES

Sterling-ES is a manufacturer representative and distributor in Salem, Va. We put our 17 years of hands-on, engineering solution experience, factory training and good common sense to work for you with real, human-to-human conversations and custom-tailored solutions. Just because we’re product experts and sell the newest, most advanced and rugged industrial automation and networking equipment, we don’t believe in automated answering services. Give us a call today to speak directly with real solution experts.


“The missing ingredients today for nearly all instrument manufacturers is lack of qualified technical support and customer service. We order everything we can from Sterling because the technical support is always available. With most suppliers, you get no response unless you have a complete catalog number. Sterling-ES just gets the job done.”
