Our Story

GTI Fabrication was built on a simple belief — that American manufacturing can still set the global standard for quality, precision, and reliability.

Founded in Buffalo, New York, GTI began as a small fabrication shop supporting defense and disaster relief projects. Over the past decade, that foundation has evolved into a national manufacturing enterprise with over 850,000 square feet of US production space and a team of more than 900 highly skilled professionals across facilities in Buffalo, NY, and Phoenix, AZ.

Our growth has been driven by a clear vision: to deliver integrated, turnkey manufacturing solutions that help our partners scale faster and operate smarter. Today, GTI supports customers across Energy Storage, Data Centers, and Defense, providing full-service design, fabrication, and integration capabilities under one roof.

Every project we build reflects our values — engineering excellence, operational discipline, and customer partnership. GTI’s team takes pride in combining world-class technical capability with the agility and accountability of a privately held company.

From a small regional shop to one of the fastest-growing modular manufacturers in the U.S., GTI’s story is one of strategic growth, operational integrity, and a relentless commitment to delivering results.
