One thing about chrome is that the very same quality that makes zinc galvanizing favorable in protecting a structure makes chrome unfavorable. On a zinc-plated frame, the electrolytical potential of zinc (vs. steel) protects the surface of the steel where it may become exposed by preventing corrosion, whereas with a chrome-plated frame, a tiny scratch in the plating becomes a bubbling arena of accelerated corrosion, due to the adjacent chrome surfaces overpowering (electrically) the relatively smaller area of exposed steel. Given that it's almost impossible to prevent all scratches or cracks in a chrome-plated frame, and that electrolytic action can result from mere dust attracting moisture from the air, chroming can thus result in tiny scratches becoming eroded troughs in the underlying steel. Galvanizing otoh, and even certain paint primers, do the opposite and thus protect the structure.
