It's a flat metal piece that is 8" x 34" with the thickness as noted. The thickness is relevant if you are also adding weather stripping on the bottom of the door. Unless it slides into a groove on the bottom, you may have to cut off one side of it and nail it to the bottom of the door to avoid covering the brass plate.
Unfortunately that option is not available at this time.
If you predrill tiny holes a little smaller than the screws that come with the kick plate the screws should work. You will just need to hold or tape the plate to the door where you want it and then mark the holes. You might want to take the door off the hinges and lay it on the floor to drill it. Just make sure you are not damaging anything important inside the door.
This product is 8 inches so check if you have enough space to replace 6 with 8 inches plate. My old kick plate was6 inches that I replaced with 8.
I wouldn't glue it on since you may need to replace it in a few years. They do get worn over time. Trying to pry off the glue may damage your door. Use brass screws.
I use just a dab of dishwashing liquid (for mud or dirt), wipe it off with a damp cloth, & dry it. The shine is still there.
If you want to engrave it, I'd use a very light touch as to the thinnest of the plate; however it does the purpose for its intentions.
It is unlikely magnetic tape would hold “tight enough” to avoid slipping / shifting when door flexes as it opens-closes, much less slams. This is especially true if door has coat of paint.
These are decorative, not structural. They attach to face of door with small screws which would not give significant strength to frame of door, but would cover up a damaged door face. Mine is mounted on a metal (faux wood) entrance door.
The pilot hole is 5/64. I believe the screws were 1/8
