I have air vents and an I-beam right when you walk into my basement. My family is tall so I am not looking to box it like I normally would. I am going to hit everything with white paint. Problem is on the outer walls how do you "connect" the drywall to the I-beam and vent that run across?

Interesting problem. If you've got metal vent, and a steel I-Beam, those will definitely move at different rates than drywall on wood framing. Sounds like you need something flexible for the transition. What about using self-adhering flexible membrane flashing material as (at least) part of the solution?
I know you can get flex membrane flashing with a white surface, but I don't know if any manufacturers offer a paintable product.
Also, I'm not sure how to make a smooth transition from the membrane to drywall, but it might be possible with some careful mudding. I haven't actually used membrane for this solution, but I am a big fan of the product for other purposes. Here's a discussion article that mentions many types.
Let us know what you end up doing?

What does "move at different rates" mean? Pro tip: if the I-beam in your house is moving, get out.. don't worry about the paint.– gregmacCommented Aug 19, 2013 at 4:16

@gregmac - OP stated the I-beam and ductwork exist when one walks into the basement. Presumably this means they disappear when one walks out of the basement. Obviously they come and go :)– mikeCommented Aug 19, 2013 at 4:57

I-beams, like most things, expand and contract with thermal changes. So does metal ductwork. Porous materials, like wood and perhaps even drywall, also swell and shrink with changing humidity. In short, everything moves.– jbbenniCommented Aug 19, 2013 at 11:35

Perhaps the best solution for the transition is to simply use a small molding around the drywall edges of the I-beam and ductwork. Caulk the molding if needed.– jbbenniCommented Aug 19, 2013 at 11:38
I'm not sure if I'm following all the details, but it sounds like one question is how do you finish the drywall around the I-beam where it will enter the sheetrock.
I did that in my basement, and a bit of caulk was all it needed between the sheetrock and metal. FWIW, consider painting the I-beam a bold color. Make it part of the "look".
As for the air vents, I'm not sure quite how that fits into the big picture. Some drawings/photos may help here.

I will add some pictures tomorrow. Caulking might work. It will certainly be a tough cut to get close.– DMooreCommented Aug 19, 2013 at 6:07
Why can't you box it in and use 1/4" plywood for the bottom of the box? That would only lower the ceiling height 1/4", which is not that much. (Plus if you're going to bump your head, better to be on some plywood and drywall than a steel beam.)

I am fine with doing that but I am worried that the beam by itself will look better everywhere except where it meets the drywall. Painted a cool looking color that contrasts I think they will look cool. I thought about plywood but think even after painting it will look cheap.– DMooreCommented Aug 19, 2013 at 17:55
Normally ducting and I-beam are not more than two feet wide combined. If the width is 24 inches or less then frame vertically from ceiling where the bottom of frame-wall is flush with the bottom of I-beam and ducting. Fasten sheet rock to the bottom of the drop walls on each side of the ducting. This way the thickness of the drywall will be the only additional drop.
To integrate beams and venting with drywall, follow this step-by-step guide that ensures a clean, professional finish. This approach applies whether you're working with exposed beams, HVAC venting, or decorative ceiling features.
Step 1: Assess the Space
Identify the beams and venting layout: Ensure you know the exact location of the structural beams and venting systems (e.g., HVAC ducts). Measure clearances: Measure the spacing between beams and vents to ensure drywall can be installed without interfering with these elements.
Step 2: Plan for Drywall Installation
Frame around beams: Use framing materials such as 2x4 studs to create a supporting structure around the beams and vents. Leave space for venting: If the venting passes through the drywall, plan cutouts for the vents to avoid obstructing airflow.
Step 3: Install Drywall
Cut drywall for beams and vents: Measure and mark where the beams and vent cutouts will go. Use a drywall saw or utility knife to carefully cut out sections for vent openings and spaces around the beams. Attach drywall: Secure the drywall sheets to the studs with screws, working around the beams and vent cutouts.
Step 4: Finishing Around Beams and Vents
Install drywall corner bead:
Apply corner bead around the exposed beams to create clean, sharp edges where the drywall meets the beams. For vent cutouts, use a corner bead to frame the opening and prevent cracks. Tape and mud:
Apply joint tape and compound (mud) around the edges where drywall meets the beams and vent cutouts. Feather the mud for a smooth transition between drywall and the beam surfaces. Sand between coats for a seamless finish.
Step 5: Install Vent Covers
Attach vent covers: Once the drywall is finished and painted, attach vent covers (grilles) over the cutouts. Ensure the venting is fully functional and airflow is not obstructed by drywall edges. Step 6: Paint and Final Touches
Prime and paint:
Apply primer and paint to the drywall, including areas around the beams and vents. Choose a paint color that complements the beams, especially if they are exposed wood or painted accents. Seal gaps:
Apply caulk or flexible filler around vent openings and beam joints to prevent air leaks and ensure a polished look. By following this process, you’ll achieve a clean integration of beams and venting with your drywall installation. Make sure to plan for vent placement and maintain structural integrity around beams for the best results.
Extra deep U-channel affixed more or less rigidly to the vent and beam, with the dry wall free floating in the channel. Don't create a paint-seal between the drywall and the U-channel or it'll look uglier than whatever when it shifts over time, so cut in with at least a coat of primer on the dry wall before assembly.
You will likely need a forklift for this project, likely a big fork lift.
