Hi, is the a specific low coast metal, or a treatment for it (like powder coating or something) that would allow it to be in the arizona sun and not burn people?

I'm looking to cover the face of a stucco wall bench by my pool. I have aluminum siding on the grill, and lots of bright colors. I'll probably end up paining it, but a powder coated metal would look awesome. I just don't want people getting burned as the sit.

thanks
