We use SS ATR on a regular basis due to the fact that the hot dipped rod does not work! The galvanizing comes off as you make it up in most cases and in some you have to file it down to get it to start. The SS is expensive but much easier to work with. Greg

We have a project requiring hot dipped galvanized (HDG) all thread rod in a parking garage (concrete tee construction). The engineer is adamant that everything should be HDG or stainless. Electro plated finish is out. We are looking at using stainless steel hilti HDIs. However some of our field people are concerned that HDG atr will not screw into a HDI or a standard 3/8" or 1/2" rod coupling. One person remembered a project years ago where he had to use couplings with a special type of thread that would accept HDG threads. Does anyone have any thoughts or experience with it? We have been asking vendors and manufacturers but no one (so far) seems to have any idea.
