HVAC Duct stiffening
HVAC Duct stiffening
(OP)
Can anyone suggest some links on HVAC duct beading, Cross breaking,pleating and bead stiffening?
what are the disadvantages ? Why is it that some specifications do not allow the above? Instead external stiffeners are recommended

RE: HVAC Duct stiffening
Some sites I'd suggest looking into for more information would be ASHRAE's website and SMACNA's website. Both of these should have some information on ducting that might be able to give you more concrete answers than I'm able to.

reduces chances for grease (in kitchen exhaust app.), water ponding (Legionella), dust & mould (IAQ), etc. etc accumulating in horz. duct.
As Istre mentioned above, as duct sizes increase the
plate thickness and mass increases. I would also
check DW 143 (issued from UK).
my 2 cents.
cheers.
