How do you attach drywall to the interior of the building?

In order to attach dry wall to the interior of your buildings you will need to add vertical steel or wood studs in between columns and then attach the dry wall by screwing it onto the studs like you would with any dry wall.

Here is an example of the process with wood beams but like I mentioned above, you can also use steel studs.
