Yes it is expensive; but it's fit for purpose. |
We use very similar stuff on my big truck. I think I may have the only Class 8 truck on the planet with a bellypan.
Strong and lightweight, Alumalite is the same weight as .040 aluminum sheet metal, yet 50 times stronger. The stuff we use is close to 1/4" thick, so it's slightly thicker than the Grimco MaxMetal. And the 1/4" thickness allows us to utilize standard 1/4" I.D. "H" channels to butt two sheets together, up to 102" wide.

I buy the black matte finish, product. It looks way sexy and one can actually see it when looking downward standing behind the cab, or when the hood is open.
