Do slugs like metal?

Some slugs enjoy hiding under dead leaves, on rotting wood and they delight in plastic. Turning over rocks and terracotta I will often find them snoozing. But do you find they like metal? Are metal containers (pots, troughs), bed edging, trellising etc less attractive to them? Do find that slugs are less likely to scale rusted containers than, say, plastic?
(This is not a question about copper).

Hiding from the sun squeezed under a bit of metal in the sun would kill it - and may freeze in the cold
Wisdom is not putting it in a fruit salad.
Interesting @Skandi - so by you they are not actually sitting on the metal, but sheltering under it? They don't have to touch it at any point to get there?
From reading all the slug related posts I don't think anything will stop one hell bent on feasting on your plants.
