SMACNA Releases Major Updates to Two Duct Construction Guides
The Sheet Metal and Air Conditioning Contractors’ National Association released major updates to the Seismic Restraint and Industrial Duct Construction manuals, which are available digitally and in print to all members of the trades. Non-members can create a free account to purchase the manuals.
The Seismic Restraint Manual: Guidelines for Mechanical Systems, 4th Edition introduces an extended list of bracing options, additional material thickness selections and refined anchor system guidelines to meet varying seismic risk levels. The manual explains how very low- and very high-risk areas of the country can be accommodated and is updated to comply with current building codes.
The Rectangular Industrial Duct Construction Standards, 3rd Edition features enhanced pressure capacity tables, additional duct construction options and expanded temperature design capabilities for stainless steel ducts. A thorough review of the previous edition was conducted by SMACNA’s Rectangular Industrial Duct Construction Task Force, which resulted in this new edition. For more details, click here.
