The manual explains how very low- and very high-risk areas of the country can be accommodated. The new edition includes a more extensive list of bracing options and has been revised to comply with current building codes, all within a single document for user convenience.
SMACNA® Rectangular industrial duct construction Standards, 3rd edition — 2024
The 1980 edition of the SMACNA® Rectangular Industrial Duct Construction was the first publication to address the selection of duct gauge and reinforcement for rectangular industrial duct systems. The 2004 Second Edition was updated to include a more “user-friendly” version of the original publication.
