The Trimotor and Junkers JU 52 both utilized corrugated sheet metal in their day, however, you'll notice that no contemporary aircraft incorporate it in their design.
If it's all you can 'budget' for, then it's 'way out ahead of nothing', but has no intrinsic advantage compared to 'smooth' surfaces.
