Zinc should never be used with treated wood. You use zinc for regular wood only.
Even though the way of pressure-treating lumber has adapted, specific fasteners will still experience accelerated corrosion. Specifically, zinc and hot-dipped galvanized screws will corrode over time when used in pressure-treated lumber. However, the thickness of the zinc coating will determine how quickly corrosion will occur.
For the longest time I thought pressure-treated wood meant it was treated with pressure. Only just crossed my mind that it means they use pressure to get the treatment chemicals further in the wood.
