We have an existing storm water lift station with a steel platform + grating at the bottom (+/-20ft below grade).
This is Houston, so it's hot and humid all the time; and especially hot & humid at the bottom of a dark wet well with flowing water in it.
Currently the HDG grating panels are too heavy to be easily removed for access to a sump pump so the operator would like us to come up with a better setup.
We are looking at replacing five rectangular steel grating panels with aluminum ones. (Approx. 2ft by 4ft grating panels). As of now, there will be no connectors. The panels will just rest on the HDG beams.
I am concerned about galvanic reaction between the dissimilar metals; and what I can do to isolate them.
Questions:
1) Should I be concerned about this; or not worry about?
2) Is there a paint/coating product that could be applied to the top of the existing beams? Or a very thin neoprene type pad that could be glued to the beam flanges?
Thank you in advance for comments.
