This webinar demonstrates how to use SMACNA's Third Edition of the HVAC Duct Construction Standards to determine the proper range of construction options of rectangular duct used in today's commercial market.

The topics covered will include:

• How to use the rectangular duct pressure class tables
  • Determine the proper panel gage
  • Determine the use/limitations for transverse joints
  • Determine the proper reinforcement type
  • Determine the proper reinforcement/joint Spacing

• How to use the new tables for T-25a/T25b (TDC/TDF) transverse joints
  • Determine the proper location and number of tie rods
  • Determine the proper external reinforcement

• Proper Tie Rod selection
  • Determine the quantity of tie rods required
  • Determine the type and size of tie rod required

There will be multiple step by step examples showing the selection process for internal and external reinforcement, selecting the proper transverse joint type, selecting the proper seam type.

We will also address other common questions and concerns when the standards are applied.

Anyone involved in the construction, estimation, or installation of ductwork is encouraged to attend. Estimators, Foremen, Superintendents, and Project Managers will benefit from this program as an introduction to the manual or as a refresher to ensure they are operating their shops in the most cost-effective manor with regards to rectangular duct fabrication.
