Are you able to attach your file with the paper clip icon?
Hmmm... I don't see it here.
Could you try one more time?
This steel beam size is to span the 25' supporting 12' long joists and a 125 psf LL for a light storage in a warehouse.
You can plan for a W16x45 beam ASTM A992 Gr. 50, but the joists will need to be detailed to brace the beam against lateral torsional buckling.
Assuming the system is braced laterally with rods or something similar, you can plan for 5x5x3/16 tubes. This assumes axial load and not eccentric connections.
W8x18 with the same bracing requirements against lateral torsional buckling.
No problem. I'm happy to help. Good luck with your project.
