Hello!
When bolting to the hollow section using Hollo-Bolts (bolt hole drilled in the wall of hollow section as shown on attached image) is it good practice to use mastics to seal joint to prevent uncontrolled corrosion inside of hollow section?
Thank you for your answers.
Hi!
I have been said that it is a good practice to keep 10mm gap between edge of grating and edge of steel. What is the reason for that?

Please note, I do not mean edge between adgacent grting panels.
Thank you for your answers in advance!
