What kind of hardware are you using? I ran into weight problems one year when I used 1 x 1/8 angle to protect the edges. Now we are using 3/4 x 1/16 angle on the 5" ends, 1/2" on top and bottom edges.

If that doesn't help, the only thing I can suggest is to make one or more of the bumpers smaller. You'd have to eliminate about 8-10 linear inches, still covers far more than 2/3, and if done judicially would most likely give you the protection you desire. Good luck.
