Large Custom Metal Fabrication Services

GMFCO was privileged to lend our custom fabrication expertise to create a “Don Draper” bench, designed by NYC firm Pentagram. The functional monument was designed to commemorate the final season of AMC’s Mad Men, and sat in front of the Time-Life building for the summer of 2015 (Read more about it here)


GMFCO is distinguished from its competition as a leading large custom metal fabrication company due to one “big” reason: We have the in-house capabilities to produce large machined parts that many other metal fabricators cannot accomplish.


All of our large custom metal fabrications are manufactured at our 70,000 sq. ft. facilities in Hudson, NH. Here, we house an exhaustive list of competencies that enable our skilled team to provide CNC machining services capable of meeting even the most challenging requirements when it comes to both size and precision.
