Galvanized sheet metal for plenum?
 

I need to replace a piece of HVAC return air duct. It's just a simple box and the HD and Lowes stuff is thin junk. Recommendations? Been waiting on a friend to get this for me, but that's just been a waste of time.

try a/c-heat contractor

Have never had to replace a return. Have rebuilt several supply boxes in the slab. Might try this manufacturer, most likely, they may supply heat & a/c contractors in your area

Greymetalsouth might be product in your area too.

Try a local HVAC supplier parking lot. It takes a good guy just a few to bend it right up if you have the measurements and male & female ends determined. Most of them I know are fun to hang out with on Friday afternoons. My neighbor has a massive break that I use to make sheetmetal projects with. I have to get it done before the jug comes out though or I forget what I went over there for.

Forget the sheet metal. Where's that jug? :cool:

get one of those sheets of fiberglass duct board and some silver tape .

The location is at floor level right in a higher traffic path where durability is important. Kicking and hand-trucking past is an absolute.

Put some bead board on it with molding around it. Plexi over it if necessary.

sheet metal is required on discharge side of heat strips

Thanks all.
