SMACNA of Western PA, a chapter of the Sheet Metal and Air Conditioning Contractors’ National Association (SMACNA), was founded in 1943 by a like-minded and driven group of professional sheet metal contractors dedicated to improving all aspects of their industry. Today, these same motives compel our diverse group of members to work toward furthering the goals of this association. Member contractors are actively engaged in all phases of sheet metal fabrication and installation, including HVAC, architectural and specialty fabrication, manufacturing, testing and balancing, kitchen work, roofing and fire life safety.
