typical gauge for ductwork
Generally, the thickness of HVAC ducts is standardized into 0.5 mm, 0.6 mm, 0.8 mm, 1.0 mm and 1.2 mm. The corresponding duct gauges are 26, 24, 22, 20 and 18. The most common duct thickness is 22 gauge or 0.8 mm.Spiral Manufacturing Co., Inc. single-wall, rectangular duct fittings are factory fabricated to furnish you with a high-quality line of products in a broad range of standard sizes. To minimize field assembly costs, rectangular duct is supplied . A sheet metal gauge tool is used to measure metal thickness and shows both the gauge number as well as the thickness of the metal in thousandths of an inch. Gauge thickness applies differently depending on the .

Depending on what size duct will determine the gauge required IRC TABLE M1601.1.1(2) GAGES OF METAL DUCTS AND PLENUMS USED FOR HEATING OR COOLING DUCT SIZE GALVANIZED ALUMINUM Minimum Thickness (inches) Equivalent Galvanized Gage No. Minimum Thickness (inches) Round ducts and enclosed rectangular ducts 14 inches or . Sounds to me that the guy with the 30 gauge may be buying it from a supply house who sells it pre made.I dont know to many sheet metal shops who make duct work in 30.I prefer 26 myself and think a sheet metal shop that makes it in house is much better than the pre made. HVAC colleagues, I'm looking for the chart/table that states the sheetmetal ductwork minimum gage based on the duct width. Got Smacna, NFPA and Trane manuals for duct fabrication and it isn't within the charts and tables in these manuals. Where can I find it? Thanks in advance. JC
Iron is not steel. Galvanized sheet metal for air ducting is cold rolled steel sheet with a coating of zinc. For sheet metal, so far as I know, it is electroplated - not dip coated. It is called 'galvanized' because the zinc and steel is preserved by sacrificing the zinc - . 1st Company: 26 Gauge 2nd company: 24 gauge 1st company: hard pipe in first 6 ft of flex 2nd company: foil back flex, metal outer covering 1st company: Trane XB13c (13 SEER, 80% A.F.U.E.) 2YCC3048A1120A 2nd Company: Trane 13 Seer 4 ton Both companies say their installers have been with them a long time and they do not subcontract. Another method involves using my Dewalt cordless minigrinder with metal cutoff wheels. It makes a dust cloud, sparks and stinks and you get a wicked burr but it is fast and I can usually cut pretty straight. Wear goggles--not just safety glasses and an N-95 respirator. Ditto on the fwd. pressure to prevent those nasty 'cat's whiskers'.
The first duct job I ever did was made by screwing a piece of flat sheet metal to the bottom of the floor joists. It was 2" wider than the required duct width. Each edge had a slip on it. The sides of the duct were 1" by 8" by 1" channels of sheet metal. I apologize if this is an inappropriate post, but I’ve learned a lot reading this forum so I’d thought I’d ask. I’m having my local sheet metal shop make all my new ductwork, but money is a little tight so I’m making all the fittings, reducers, etc. Is there a formula figuring the length of reducer or just as long as it’s not to .
Metal is always best Reissgirl- We had the same issue a while back with the foil back insulation falling off and we found that using a Bostich outward clinch stapler helps and/or spray adhesive on the metal before insulating. Now .
