## About The Pull Request

Great success for #92975 

	resistance_flags = INDESTRUCTIBLE

Prevented cables being placed on that reinforced catwalk
Allowed just cables to be placed but the things are still unable to be
damaged in testing

I also made sure it does not affect regular catwalks
| Cannot place cables still | Need to remove cover |
