I will be using 10-ft x 2" x 6" treated lumber for a rail. Will treated wood used as a rail warp?
Let me explain the application:
I have a 10-ft 2"x6" piece of treated wood that will be attached at each end (with screws) to two 4"x 6" steel bases anchored to concrete.
I assume that length-wise it won't warp since it's anchored at each end. Width-wise, the 4"x6" steel base will have (4) holes on each corner holding the piece of wood. My thought is that there's no way it will warp since all the area (width-wise) is held down by a screw.
