HARD TO FIND A BETTER PROVIDER
Our company provides services to aid in the manufacture of technological products, such as semiconductors and flat panel displays, and often searching for distributors of obsolete product we require can waste time and money. Finding GID Industrial proved to be a great asset to our company, with cost effective solutions and superior knowledge on all of their materials, it’d be hard to find a better provider of obsolete or hard to find products.
Applied Materials
CONSISTENTLY DELIVERS QUALITY SOLUTIONS
Over the years, the equipment used in our company becomes discontinued, but they’re still of great use to us and our customers. Once these products are no longer available through the manufacturer, finding a reliable, quick supplier is a necessity, and luckily for us, GID Industrial has provided the most trustworthy, quality solutions to our obsolete component needs.

TERRIFIC RESOURCE
This company has been a terrific help to us (I work for Trican Well Service) in sourcing the Micron Ram Memory we needed for our Siemens computers. Great service! And great pricing! I know when the product is shipping and when it will arrive, all the way through the ordering process.

GO TO SOURCE
When I can't find an obsolete part, I first call GID and they'll come up with my parts every time. Great customer service and follow up as well. Scott emails me from time to time to touch base and see if we're having trouble finding something.....which is often with our 25 yr old equipment.
