Since your'e embedding galvanized anchors in concrete remember that corrsion
of the zink content in the hot dipped galv plating is worse the higher the
pH of the concrete during the curing process. Very high pH in wet cement is
normal.
If this is a large job you might want to check with the concre

I haven't used neoprene, but I usually use SS washers to isolate dissimilar
metals. Painted or powder coated steel doesn't always need this, but galvanized
definitely would. How careful we are with these issues is proportional to the
distance from the ocean. In New Mexico you can get away with a
We use ss anchor (L) bolts when we need to bolt to pillars. Remember to
