*This table is similar to table in SMACNA in that it assumes a 6” space between duct and hanger rod.
L = Distance between rod hangers
d = Distance between hanger rods and ductwall. Above table assumes duct is centered between hangers
P = Total weight of duct including reinforcements, connections, insulation, etc.
NOTES:
- For d greater than 2 inches, the 6 inch table must be used.
- See page 4-12, figure 4-5 of SMACNA’s HVAC Duct Construction Standards - Metal and Flexible for calculation method.
- Load and deflection listed are based on calculation using 25,000 psi stress.
Section properties:
- Effective Cross Sectional Area (A) = .165 in 2
- Effective Moment of Inertia (I) = .184 in 4
- Effective Section Modulus (S) = .170 in 3
- Available Materials:
- Galvanized Steel - ASTM A653
- Stainless Steel - ASTM A480 Type 304L or 316L
Installation instructions are available in the Spec Data file for this product. Please refer to the Ductmate Library.
