We bought gridwalls to display our sublimated metal prints. Our problems are: What is best for securing the metal prints to the gridwalls so they do not fall off. The s hooks we bought were small so it did not feel secure. The metal prints have mounts on them or a wood frame mount on the back. We will be displaying sizes from 8" x 10" up to 24" x 30". We are also concerned up the metal prints not getting damaged by the metal wire grids.
