If you have the mesh C+C grids, you can bend them so that they have sides, then it is basically a * shape, use cable ties to attach them to your C+C cage. My husband did this with two and attached them together again using cable ties and slightly overlaping them so that they were strong in the middle. Then just use fleece or vetbed to cover it so that they can get up and down. No need to stick it down just tuck it underneath at the top of the ramp.
