What construction equipment could possibly need an indestructible fence surrounding it?? Most construction sites have chain link or orange plastic fences, and they’re not to prevent theft. You hire security or insure the equipment against theft to protect against theft.

Anyone that owns heavy equipment carries insurance covering damage, theft, and liability. Otherwise it’s rented and Sunbelt or whoever is on the hook to replace it.

Safe and vaults, sure.

The fence is to keep 5 year olds out. As the parent of a 5 year old I'm not sure this is strong enough to do the job.
