Does anyone know about timber preservatives?

Does anyone know about timber preservatives?

(OP)
Just need to know more about timber preservatives and their effects (if any) on corrosion rates of hot-dipped galvanized bolts in hardwood structures?  What is the standard curing time for the hardwood timbers?

RE: Does anyone know about timber preservatives?

The old ones are all CCA copper cianide compounds.  The new ones are based on ACQ Alkaline Copper Quaternary and CA Copper azole .  These new treatments must use higher levels of active chemical to get the same effects, and they are more corrosive.
Try these:

There are also treatments that use boron compounds.  I like these better than ACQ and CA.

But in any case, good heavy hot dipped galv should be fine.  Don't use any Al, and don't use light galv.

Corrosion never sleeps, but it can be managed.
