Hanging perches in corrugated steel part of aviary - how?

[Stephanie]

I have an aviary that, for the first, time has a sheltered section made from corrugated steel. I need to attach perches all through this area and like to use natural sticks and branches. How can I attach them?

I can reach the tops of the panels (about 2m high) so could hook something over there and run it down the panels, and attach the sticks to that. I just don't know what.

Does anyone have recommendations for a good way to do this please?

Thanks

Here is a link from when another member was having problems with hanging perches, some rather ingenious ideas were given. Hope it helps
