We have a city that requires push-through letters that have at least a 3/4" reveal and a client that wants the entire face to be lit. The cabinet is essentially a 5' diameter circle. Our concern is the polycarb face not being able to withstand the weight of the push-through letters. Anyone have any advice? We had looked at thermoforming but the lead time was too long and most vendors were only able to do 1/2" off the face.

Push-through cabinet that is face lit?

What are you referring to as far as:
As far as lighting a push through sign, pushed through polycarbonate, you'll have some artifacts where the lip of the letters rest, and if you glue it the poly will likely tear over time, and if you mechanically fasten another piece to bind the lip in place you'll have a series of mechanical fasteners to hide. Sounds like a traditional push through would work.
And as far as poly supporting weight of acrylic and aluminum, we've done push throughs where the parts were nested inside one another, as long as you have a piece of poly spanning everything and plenty of extra fasteners around the outer most perimeter, it'll hold just fine. In this picture, both the wallsign and monument have the e as a push through, with the grey circle as another pushthrough, all affixed to an outer .125" aluminum ring, that is fitted into an F trim retainer.
Reveal around the letters, or letter that protrude 3/4"?

Why do push-thru? If a 3/4" projection is called for, bond 3/4" characters to a flat face, they will look the same as push-thru.

While something like channelbond would do this, the different expansion rates of the two will literally tear the two apart over time.
