Manufacturer of maple plywood panels?

Sorry, we don't have that information available, but it shouldn't be too difficult to find if you ask you local building supplier. It is a maple veneer that you would be requesting - this is a thin cut of maple (a veneer) attached to the outer face of the plywood substrate.

What finish did you use on the plywood panels? Thanks.

I think the maple veneer plywood came prefinished. I believe it was a polyurethane finish.

Thank you!
