Supplying high quality, low cost parts is our passion.

Many companies struggle putting together continuous and trusted supply chains that follow a program from product inception to end-of-life. This lack of continuity creates communication errors between internal resources and suppliers, costing time and money. We see this most often when transferring from pre-production to production.

GTI has over 50 years of combined industry experience where we have seen and lived this problem first hand. We work hard to provide commercial and military OEMs comprehensive support from design to prototyping to pre-production to production.

80% of successful product lies in the final 20% of design.

Tolerances, material optimization, tooling details, that's where programs succeed or fail. GTI specializes in getting that final stretch right.

Commercial + Military

Defense programs have different documentation, certification, and supplier requirements than commercial programs. We work both sides and know the difference.

What We Do

Sourcing, program management, and design consulting for metal parts, with a specialty in magnesium that very few suppliers can match.
