JGM is a national, self-perform industrial contractor and structural steel fabricator — built to take on the fast-track, high-complexity projects other companies turn away. Founded in 2001 and still family-led today, JGM operates AISC- and ASME-certified fabrication shops in Coatesville and Sinking Spring, PA, plus a national Construction Services team performing erection, rigging, hauling, and industrial construction for Fortune 500 clients across power generation, pharmaceutical, mining, steel and metals, infrastructure, and manufacturing.
We don’t subcontract our workforce — we build it, direct-hire, from the shop floor to the field to the front office. Safety comes first in every role at JGM, not just on the job site — because taking care of our people is something we’ll never compromise on. Paired with real apprenticeship and leadership programs behind every role, JGM offers more than a job: it’s a career with a company where family is our foundation and whatever it takes is how we get it done.

When the project is complex, the schedule is fixed, and failure is not an option — industrial owners call JGM.
We are a turnkey self-perform industrial construction and fabrication partner built for Fortune 500 owners who need more than a contractor. They need a team that engages early, controls every critical scope, and delivers with certainty in the most demanding environments on earth.
What makes JGM different:
We self-perform everything. Steel erection, structural fabrication, process piping, OEM equipment setting, precision alignment, heavy rigging and hauling, metal siding and roofing — executed by our own skilled workforce of ironworkers, fitters, welders, millwrights, and boilermakers. Single-source accountability from first plan to final bolt.
Safety and quality aren’t managed on our projects — they’re engineered into them. From early engagement through closeout, our Falcon Flight Plan ensures every phase is planned, controlled, and executed with safety as the foundation.
We specialize in solving what others won’t take on:
▸ Active operating facilities and live plant environments
▸ Critical outages and scheduled shutdowns
▸ Heavy, complex, high-consequence installations
▸ Precision, tolerance-driven work with no margin for error
Backed by 25+ years of proven execution:
▸ ENR Top 600 Specialty Contractor — 2024 & 2025
▸ AISC Certified Fabricator (Structural Steel + Advanced Bridge + Fracture Critical Endorsement)
▸ AISC Certified Steel Erector
▸ ASME “S” & “R” Stamps
Founded in 2001 by Joseph Messner Jr. — fifth-generation steel and industrial construction — JGM has grown from a garage startup to a nationally trusted partner for owners in Mining & Minerals, Metals, and Power.
We don’t just build facilities. We build confidence.
WE CAN. WE WILL. WE DO.
