Protecting metal components from ACQ pressure treated wood.

It is important to understand that the corrosive nature of ACQ treated wood comes from electrolysis, not a low PH(acid) quality of the lumber. One of the easiest ways to use a non ACQ rated metal component is simply to insulate it from the copper in the treated wood with an adhesive flashing barrier. This interrupts the conductivity between the steel component and the copper in the wood. This is actually a building code approved method for when a hanger or other engineered component that is unavailable in a resistant form must be used. In the photo you can see how I have bedded the post with a strip of Vycor “deck protector and then scored the outline of the hinge to remove the excess flashing around the hinge. You can learn more about ACQ and electrolysis in my related post below.

Proper techniques are essential to ensure long life of fence posts

The fence post pictured is only 7 years old, this fence had many years of life left except for the breaking posts. Even pressure treated posts can be vulnerable to decay if not installed properly. Excluding the direct contact of soil to the post is an important part of a good installation. Decay is not the only enemy, when water is allowed to pool right where the post meets the concrete, caustic chemicals in the concrete are able to weaken the post.

I always make sure to create a small pyramid of concrete around the base of the post to route water away from it. this moves the exposed post a couple of inches above the grade of the surrounding soil as well. Most posts are 4×4 in size but, MBA Deck and Fence uses a special 5×5 post which is extra strong and resists warping too.
