Hello. How are you doing? I'll be happy to assist you
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.
What setting will the deck be used in?
That will make the beam larger
