Who Is SMACNA?
Located in headquarters outside Washington, D.C., the Sheet Metal and Air Conditioning Contractors' National Association (SMACNA) is an international association of union contractors located primarily in the United States and Canada. SMACNA's mission is to provide products, services, and representation to enhance members' businesses, markets, and profitability.
Association Goal
SMACNA exists to address issues common to member firms that impact the
industry nationally and internationally. It serves members' needs to
improve their business environment through industry education, labor
relations, standards, industry representation and business studies.
Member Profile
SMACNA members perform work in industrial, commercial, institutional

Technical Manuals and Standards
The voluntary technical standards and manuals developed by SMACNA Contractors
have found worldwide acceptance by the construction community, as well
as foreign government agencies. ANSI, the American National Standards
Institute, has accredited SMACNA as a standards-setting organization.
SMACNA does not seek to enforce its standards or provide accreditation
for compliance.
SMACNA standards and manuals address all facets of the sheet metal
industry, from duct construction and installation to air pollution control,
from energy recovery to roofing. SMACNA's Technical Resources Department
fields several thousand technical questions annually from architects,
engineers, manufacturers and government personnel.
