Anyone installed a pole in a place with aluminium ceiling joists?

Got a workman round today to do stud finding for me as my stud finder was giving weird readings. He said he thought the ceiling of our (rented, ground floor) place had aluminium ceiling joists which weren't very strong: he was humming and ha-ing about whether a spreader plate/tension mounted removable pole would push up and buckle aluminium joist and thought drilling in to attach a small permanent mount (like a Lil Mynx) would be safer. So thought I'd ask if A) he was being unduly pessimistic about the chance of an xpole xpert damaging the ceiling B) if anyone had experience of installing a pole in a place with aluminium joists. Thanks v much.
