Does the metal get hot in the sun?
The metal surface ends up reflecting most of the sun’s heat and, while it does get warm, it doesn’t get overly hot to the touch and won’t result in your soil overheating.
Is galvanized metal safe for the garden?
Galvanized metal is coated in a layer of zinc which has been bonded to the steel. Heating the steel to almost 400 degrees or exposing it to highly acidic materials can cause this bond to break down, but this should not be the case in your garden.
