Angle grinder proof locks - what about the bike stand ?

[Loagi]

I've watched some videos about the relatively new angle grinder resistant bike locks, and I'll likely buy one.

But it did occur to me to wonder how many bike racks or railing that are locked to are also angle grinder proof/resistant ? Most seem to be a bit of hollow mild steel tube.

Can you even get a hardened steel bike rack/railing ?

I am thinking of putting a heavy duty eye bolt anchored in the concrete in my garage for locking my bike to. But its also the same garage with my angle grinder, oscilating tool with carbide blades (cuts stainless steel bolts great !), and recipricating saw with metal cutting blades
