I'm considering using regular saddle clips and field drilled holes, or clamp-style grating clips for securing grating panels. My concern is with long-term rust protection, as the grating and framing members will all be hot dip galvanized. in my situation, making a call on this is within my scope.
if the erector field drills holes, the galvanizing will naturally be removed within the hole. I can tell them to touch up holes with a cold galvanizing compound and ensuring it is fully cured prior to bolt installation. not sure how well this works.
if i used clamp-clips, i'm concerned that the clip "teeth", or serrations, that bite into the underside of the beam flange will also damage the finish. Lindapter makes one without teeth, but i still have concerns.
how have you handled this on similar projects?
