Stucco on corrugated steel?
Stucco on corrugated steel?
(OP)
Wire lath screwed to the ribs of the steel wall, two layers of paper, no other substrate.
Weep screed at the bottom.
Appropriate control joints.
What do you think? Is some additional substrate, such as plywood, necessary?
Thanks.

RE: Stucco on corrugated steel?
The other thing I would be concerned with is temperature expansion/contraction stresses of steel sheeting causing cracking in the stucco. If anything I would use densglass screwed to the ribs. This would somewhat isolate the densglass from the steel panels because the screws would yield/rotate slightly with expansive/contractive movements of the panels. Also it may help with your moisture barrier and temperature change issue in your wall section.
I've seen a lot of ugly stucco on plywood applications, moisture can wreak havoc on this system, so I would never recommend it. But maybe it works OK in dry climates, certainly is bad in Florida.
However, you may also be creating a moisture barrier/intrusion problem:
-Project location? Climate? More heat or AC?
-Type and usage of structure?
-Interior finish and insulation?
May also see what the Stucco Mfrs Association has to say about this type of installation...

Also a good one to bounce of some architect friends to see if they have heard of this and had issues with it.

A three-coat stucco system would be required for this, installed in accordance with ASTM C926.
