I have a Don Drumm item to frame. It is a metal sun that is raised in the center. Customer wants something behind it for color contrast on the wall. We decided to put it in a frame with no glass and attach it to a matboard covered with Franks Fabric material. The sun has pins in it now that has some depth to it and looks like I can put cotter pins in it to hold it in place. Holes are already in the pins. But the piece is a little heavy (under 5Lbs) Any ideas on what to put on it for backing? Plywood, Gatorboad, or considered Plexi. Do you think that Plexi might work? It would be light weight and I could drill holes for the pins if it's possible. Thanks

I think plywood would be the more rigid and the most economical. I think plexi could bend and warp. Gator could crack. How big is it? Maybe any of them would work.

I would use 1/4 luan plywood instead of gator. Plexi can warp and bow.

How about MDF board?? It comes in several different thicknesses - and it holds up nicely. You could use 3/8 or 1/2 inch. It's a little heavy for the thicker stuff - not sure if it would be heavier than ply or not - but it would be another good choice.

MDF has it's place.... but it isn't holding weight.

The facial fracture structure of MDF makes it bad to glue anything to that may have a frontal rotation shear stress....

Always better to use a ply.... not sure I would go with Luan... with a ph of 5.5.... but that's just me.. I always have some Baltic Birch High Ply laying around in 1/4" and 1/2".... ph of 7.

Wise, good choice on the fabric, use 1/4" ply and prime, then adhear with Frank's Adhesive.

As always: Make sure you take pictures and post.

Coroplast is lighter weight than any wood-based product -- just a bit heavier than foam center board. But it will support considerable weight, it is easy to cut & fit, will not warp, has a clean, smooth surface covering with board or heavy fabric, and it is non-hygroscopic.

I like to encapsulate formed-rod mounts between the flutes with epoxy or other hard-setting glue.

10 mm Coroplast would support 5 lbs quite securely. Or you could cross-flute-laminate two layers of 4 mm
