Obviously it wouldn't be suitable for hotwork like welding or cutting, but for general shop use it ought to be pretty indestructable, especially if it's laid over concrete. If my 1500 lb quarterhorse couldn't tear it up shuffling and pawing and fretting inside a trailer, you'd have a hard time.
Only downside I can see is that of course it's black, so you don't have good light down low. It's got a hard enough durometer rating that you should be able to roll tool chests etc. on it, but small diameter, heavily loaded casters like on an engine hoist might have some increased rolling resistance.
Give it a try and let us know!
