Sheet Metal
Since the 1960s, A.O. Reed’s sheet metal, plumbing, process piping, and pipefitting fabrication capabilities have played a vital role in the successful delivery of our projects. By incorporating prefabrication strategies for ductwork, process piping, plumbing, and piping systems, we improve productivity, quality, and installation accuracy. Our in-house fabrication facilities enable assemblies to be built in a controlled environment, reducing field labor by 30%. This accelerates installation, supports compressed project schedules, and improves overall jobsite efficiency. Fabrication also helps minimize material waste, enhance safety performance by reducing jobsite exposure and congestion, strengthen quality control, and provide meaningful cost and schedule benefits to our clients.
The success of these fabrication efforts is driven by the expertise of A.O. Reed’s fabrication team, recognized as one of the best in the industry. Our craftsmen and trade professionals bring decades of experience and generational knowledge, enabling us to deliver innovative solutions, exceptional workmanship, and reliable results on even the most complex projects. Their commitment to excellence is reflected in our history of industry-leading achievements, including setting records for some of the largest fabricated ductwork recorded by SMACNA. Supported by advanced fabrication facilities and a highly adaptable workforce, our team is equipped to tackle unique challenges, develop creative solutions, and successfully execute projects of any size or complexity.
