Question on Corrosion

[eddie209]

Can wood to wood angles be attached to pre treated wood? Will these corrode?

Corrosion/oxidation will happen to the weakest/most available material first.
It depends on the material and environment it's kept in.
What environment will they be kept in? (submerged, open air)
The zinc coating will oxidize and form a protective barrier for the steel underneath.
If you scratch off the zinc coating, the steel underneath will corrode first.

These will be on an above ground pond. On 4x4's. They will be under the the underlayment. In a partial covered patio.

If you're close to the ocean, use some flat washers between the lag bolts and the brackets.
Those brackets will last many years.

I dont live near the ocean.

with the weight of water against them and treated wood being young growth trees the wood may rot over time being exposed to moisture even protected by the liner .I have even seen one here with mold all over the outside of the wood
