We have to hang a 36"x 60" 1.5 hdu sign. On smaller signs we have used 2 part epoxy and eye bolts to hang it. On this one I was thinking of using a 3/8" x 8" Eye bolt and drilling a 1/2" X 9" hole then filling it with epoxy. Am I on the right track? My thinking was that the deeper into the sign the stronger it will hold. Thanks!!

Robert, I do this quite a bit. I use ONLY stainless steel eyebolts. On the larger signs, I drill two off chutes on each side of the main hole to give the epoxy more surface area . .. . more holding power. Remember, if you don't use stainless, it is almost impossible for the customer to come back in two years and change them out when they get rusty.

A 3' x 5' HDU sign is a pretty big panel to be hanging by itself, especially if you have blasted both sides. I would be afraid of the panel warping over time, and also of the strain on the bolts, even though they are in epoxy.
What we do is sandwich two panels over a layer of aluminum, MDO, or Dibond. Any hangers are attached to this center section. This way all of the pressure is on the tougher material and not the HDU, plus it gives the sign more rigidity.
John has the right idea about using stainless steel. Just good insurance against rust. Since these signs are premium examples of quality there is no logic in using anything less that quality materials.
