42 year old wood frame 50 x 50 x 16 that has been used for farm shop work since day one. 100 degree day summers, -30 degree days in the winter.Weld, power wash, you name it its been done in it every year......If your going big, go steel, if not, go with what ya want. Guys with zero wood skills like steel and vise verse. I wouldn't say one is better than the other.
