A friend has a portable electronics "kiosk" for recharging amplifiers and electronics gear he rents for concerts and exhibits nationwide: Lots of travel, lots of loading and unloading of the aluminum assembly, but it's only exposed to humidity and environment while being shipped. The rest of the life of the gadget (assume 5 to 7 years max) is indoor or in storage between trips.
The shelf holding several transformers and power supplies has busted. (The original vender's welds simply tore through -> Obviously, they weren't strong enough to withstand stress and shock and "handle with care" signs.)
I don't want to recommend simply re-welding the Al shelf: It seems that he would be better off adding a Al angle iron (1-1/2 x 1-1/2x1/8 (?) and some legs under the shelf to stiffen it up and better support the load. (The angle iron would go under the original shelf to replace the short "tack" that failed between the shelf and interior walls.)
Is there any real disadvantage to using 3/16 or 1/4 dia steel pop rivets rather than Al pop rivets.... Or am I trying to hard, and really doesn't matter? 8<) Back side of the interior wall is not accessible, so I'm left with trying to recommend a way to attach the reinforcements without using nuts or through bolts.
