Can they handle wind loads?

Suitable for most residential fences. For tall privacy fences or high-wind areas, add diagonal bracing or reduce post spacing to 6ft.

Can I use on a wood deck?

Yes, but bolt through decking into a solid joist or blocking below. Screwing only into deck boards is not adequate.
