As per SMACNA the gauges of ducting sheet varies and depends upon the width of the duct and type of application of a particular project. Here are the few gauge system as per SMACNA standards.
Example: low and medium velocity duct system
26 gauge is use for the duct size below 300 mm (12") and thickness 0.5 mm
24 gauge is use for the duct size up to 750 mm (30") and thickness is 0.6 mm
22 gauge for duct size up to 1200 mm (48") thickness 0.8 mm
20 gauge for duct size above 1200 mm to 3000 mm (48"-120") thickness 1 mm
18 gauge for duct size above 3000 mm (120") thickness 1.2 mm
16 gauge for machine cabinet thickness 1.6 mm.
For high velocity duct system gauge ranges from 26 to 16 but thickness is different.
Note: commonly for G.I sheet 22 and 24 gauge are used in actual practice.
Hope those answers to your question.
The most important Smacna slandered are as following:
- Duct system inspection
- HVAC Systems Duct Design
- Duct Construction
Please refer to SMACNA Standard and DW 144 and DW 143,also refer to NFPA 13,14 for kitchen application of steel duct .
Smacna standard g.i. sheet gauge and weight,
I want chart sheet.
