I just had a 5U rack panel done by Front Panel Express in 3mm.  Felt 
very bendy until I attached some standard hardware store aluminum L via 
standoffs, which I'm using to mount circuit boards.  I have 2 rails, one 
top, one bottom each attached by 3 standoffs (one on each side + one 
middle).  Really makes a world of difference.  Might be tough to fit in 
the 6U x 60mm specified but worth a try.
