I am installing 2 x 1" copper risers from my basement to attic to be used for HW supply/return for a heating coil. I have roughed out the openings between floors and am ready to install the lines. I bought copper plated 2-hole straps to secure the pipes and have the following question. What type of fastener should I use to secure the straps? I'm under the impression that if I use steel screws, they will react with the copper in the straps and cause corrosion which could, over time, cause the pipes to lose their support. Any thoughts?
