tf2 metal theme

[bjuo]

Hello. I don't really know if thats the right forum but I have some problem
I'm working on a tf2 map and I really want to give a metalic, industrial theme to it. But the metal looks very bad and hard to work with comparing to the wood materials in tf2.
Most of the times when I'm trying to create metal objects and buildings I get weird looking stuff, and I don't really get that cartoon style that tf2 has.
I just want a plain, shiny metal, which is not rusty and not too realistic but fits the mood of tf2.
Can anyone give me and tips, pictures, or guides for creating a good looking metal building/theme?
