I will be making a drip shield surrounding an 18"x30"x1" fixture plate using
304 SS in 20 gage. The shield will be at a 45 degrees angle all the way
around the plate up and away from the periphery. This shield will be about 7
inches tall and hence will add 14 inches to the overall width and length of
the plate.

No it won't. The length needed to rise 7 inches at a 45 degree angle is
9.898 inches (hypotenuse of a 45 degree triangle is sqrt(2) times the rise).
So the total amount added to the length and width of the sheet will be
twice that, or 19.796 inches. This is important to know if you're supplying
the material.

Also, if you want a rolled lip on the edge (good idea if you don't want
people to be cut on the sharp edge), you have to allow enough material
for that too. By eyeball, I'd say about half an inch for the rolled edge,
so add another inch to the overall length and width dimensions of the
sheet.
