First Davis Corporation was founded as a general construction company in 1981 by the late William Davis. The company eventually transgressed into a mechanical construction company, providing Millwrighting, heavy hauling, rigging, steel fabrication, precision, optical alignment, plant maintenance (scheduled and emergency), conveyor and equipment installation services. In the past 30+ years of service, we've maintained an excellent reputation. We provide high-quality work and service in the Pennsylvania mid-state area. You can always trust our vast knowledge to get your job done right and our diligent work ethics to exceed your expectations.
