Thin cladding panel
Thin cladding panel
(OP)
Any thoughts on a 2" thin cladding panel? Panel will be about 7'-0" x 4'-0" spanning horizontal. My worries are rebar shadowing, and also spalling. Granted they will be vertical, but the bars will only have 3/4" cover.
per ACI I can do 3/4" cover on a precast wall.
Im iffy about going so thin.

I'm assuming since its so thin its not structural so your just trying to meet minimum steel.

Ask a couple local precasters if they can do them, and what they would do in the way of reinforcing, lifting, etc. Generally, I’d think they should be handled, lifted and transported on edge, so you don’t have them being stressed in the weak direction during handling. You could make a 6'-9" x 3'-9" flat/plane rectangle, with tight corner bends out of a #4 bar to reinforce the edges. Then weld a sheet of welded wire fabric to this edge reinf’g. cage. You might also thicken 3 or 4" all around the panel. This might actually be needed to facilitate securement and lifting hardware.

I wouldn't want to use a 2" panel. Even if the walls were timber or metal framed I would want them to be a minimum 3". I remember calling up a 6" panel one time and the local precast supplier wanted a minimum 7.5" because it works best with his waterproofing detail.
I don't know if you guys use AAC facade panels in the US but even those panels are normally a minimum 2.5" thick.
