Thanks fr the picture.

I’d like to point out that a Professional Engineer’s standard of care typically includes a site visit to assess field conditions and get an overall understanding of the structure. This can obviously not be accomplished through the internet. The information provided here is meant for planning purposes only (general sizing and budgeting) and is based on the information provided by you. All loading cases considered are for vertical loads only, no lateral analysis has been completed. The information should be verified by a professional engineer who can visit the site to ensure that potentially important information has not been overlooked or omitted.

Hold on while I take a look and run a few numbers.

Couple of questions:

1. What city and state are you located in for possible snow load consideration?

2. On the left side of your drawing, it looks like the proposed steel tube cantilevers out several feet, what is that cantilever distance?

It extends out two feet on the left 1 foot on the right. It is in Scottsdale az.

One more question, do the 14' span roof joists overhang the beam, like 12" to 18"?

18 inches with a 2x12 fascia

You can use a T8x6x 3/8” (50 ksi) structural steel tube for your 29’ clear span beam. The tube is 6” wide and 8” deep. You will need to have a local engineer detail your connections, size your column supports, and determine foundation requirements.

I have access to 3x6 and 3x8 beams with either .250 walls would that sag ?

Sorry to say, that would not come close to clear spanning 29'.

Ask Your Own Structural Engineering Question

That is the most compact beam you can use
