Reflectivity of steel

WebSimple answer: It will reflect. Slightly longer Answer: To some extent both and lets not forget that metal will also pass some of the energy as well. The thinner the metal the less it will absorb and the more it will pass. In all cases though the vast abundance of free electrons in a metal allow it to reflect and that will be the dominant effect.
