Hello. I can help. What size and length? Do you want to go vertically into the bottom or into the side. Top flange or bottom flange?

Customer: replied 2 years ago.
Shelve is 4' x 8'. Rated up 600 lbs. Securing vertically into botton flange.
Expert:  StructuralEng replied 2 years ago.

I would strongly recommend against hanging that type of load off the bottom flange in that manner. If the bottom flange separates from the web, you can have a very serious problem.

Expert:  StructuralEng replied 2 years ago.

I would use 2x blocking between the joists with joist hangers and fasten into the bottom of those.
