About TG Manufacturing

Our History

TG Manufacturing was established in 2007, when Owner Rich Achtenberg had a vision of utilizing modern technology, advanced manufacturing & design, and a skilled group of associates to produce world-class metal products with a more personalized, service-oriented approach.

That approach continues to be our goal today as we strive to pioneer the way in creative, original and unprecedented solutions to our customers' metalworking needs. Though this requires more effort on our part, it provides our customers with the assurance that our team is working diligently around the clock, utilizing our globally-integrated network to impart the best possible value in the metal products manufacturing industry.

We currently serve customers in many industrial sectors across the U.S. in the Aerospace, Automotive and Material Handling, Food, HVAC, Furniture, Appliances, Renewable Energies and Construction industries, to name a few, and are proud to be ISO 9001 Certified, assuring strict quality standards and metal part manufacturing practices. We are also proud to have been named #25 of Inc. magazine's top 100 fastest growing manufacturing companies in the U.S. in 2013, as well as having been nominated as one of the MCSB top 50 companies to watch in 2014.

Our Unique Position

In the metal part manufacturing industry, there tends to exist either very large companies offering a wide array of manufacturing and design capabilities, or rather small companies who specialize in a particular niche. At TG Manufacturing, our experienced staff and diverse metal part manufacturing & design capabilities allow us to serve a space somewhere in between, and as a result, we like to consider ourselves the full-system fabricated metal parts manufacturer for everyone.

We have the experience and infrastructure to manage large, complex projects for the biggest multinational customer, and yet we have not forgotten that small businesses drive our economic engine and are the big businesses of tomorrow. Our larger multinational customers appreciate our speedy, headache-erasing responsiveness, and our smaller customers value the access to the kind of one-stop shopping that has traditionally been reserved for bigger players.
