I am not aware of many rules about metal.

UL has rules about max temperature of external metal (like heatsinks).

Further there are rules about holes in metal that allow fingers to touch energized circuits inside.

Yes as I recall they use a special finger shaped metal probe to poke around. More like a pinky than thumb.

…. then only grey and black for all  ?    :(

About structure resistance depending on the weight that should be loaded ,

there is some characteristics that have to be respected ,
and related documentation for certification is required ,

or it is at the discretion of the manufacturer ?
