lvl or steel i-beam?

I just put up block for a 30x35 in-law apartment with a craw space under it, not sure which would be better to hold my floor joist, lvl beam or a steel i-beam. I have to span 35' and I can use either one or two beam jacks, need help figuring which beam I should use.. Thanks

A steel I beam will almost always be superior to an lvl. But you will want to involve a structural engineer to size either correctly.

In my area either a steel beam or LVL requires an Engineer's signature. But if you're only going 35' and can have two beams then you are easily in range of using traditional dimensional lumber which probably wouldn't require an Engineer.

Do you mean two beams together in the center or two beams 10 foot apart?

You tell us. Your description of your project is vague. If you look up span tables for traditional lumber you can see how far you can span.
