Hello. I can help
Storage loads are quite heavy. Is this as joists at 16" on center or as a primary beam?
Thank you. If this is a "light storage" area that needs a 125 psf live load. That's quite heavy. I will check the size for you
With that span and loading, you need 7" x 20" 2.2E LVL at 16" on center
32' is a long span for wood with normal loading
No problem. I'm happy to help. Good luck with your project.
