Here is an overall view of a shop built steel spray booth.
The filters are removed (except for the bottom row of green
fiberglass filters) and the steel studs and channels can be
seen. The chicken wire stretched over the studs prevents
the filters from being sucked through.
I built the wood fan support before I knew how easy it is
to fabricate steel. If I were to do it over again, everything
would be steel.
The right side wall has white peelable paint up to about the
top six inches. (I don't remember why we didn't paint right
to the top.)
This is a close up of the steel channel screwed to the
studs. Channels are mounted back-to-back and act to
capture the filter top and bottom. The chicken wire is
sandwiched between the studs and the channel.
To build a wall, you stick the end of a steel stud into a
channel, pinch hold the two together with vice grips, then
screw them together with a self taping screw. Then on to
the next stud and the wall is done in about 30 minutes or
less. The entire booth can be built in an afternoon.
And it's a lot less combustible than wood, plastic or other
flammable construction materials.
A sawzall with a hacksaw blade makes quick work of cutting steel.
