I am working on a project to create a rolling wall for a local art gallery.
Wall will be 8ft wide, 7ft tall and 1-1/2ft deep. I'm planning to frame it with 2x4s as a standard wall, mounted on top of a metal & OSB cart, and sheathed in OSB (rather than drywall)
Here is a link to an inspiration buildout video:
Now to the question.
For the base cart, I am unsure what metal to use.
I have watched DIY videos that suggested welding 2x2 square steel tube to make the frame and securing plywood or OSB to the surface. I think this may be overkill, and I don't have access to welding capabilities.
As an alternative I am exploring: Building the frame out of angles slotted steel beams and securing this to 7/16th sheet of OSB.
My biggest concern is the 8 foot span between the castors.
I will Of course be mounting 2x4 As a part of the framed walls baseplate. So this will further add to the strength.
Looking to the community here to provide some guidance:
- Is the 2x2 Welded square steel tube Overkill?
- Would the angles slotted steel be sufficient?
- Am I just over engineering this whole thing and should drop the metal all together an build the frame out of 2x4, top it with OSB, then frame the wall on top?
As a secondary question: Based on your recommendation what method of fasteners should I use for the OSB to metal.
