Is it supporting 50' long joists?
Do you want the joists sized or the beam? You used beam with the 30' span, so I assumed the joists were spanning the 50'
what kind of decking will you use and what spacing do you desire? Is this a residential deck?
I will assume you can attach the composite decking to the steel beams.
Assuming a residential deck, W8x18 ASTM A992 Gr. 50 at 16" on center. Attaching the deck boards to boards to every beam is very important to the proper performance of the beams.
