I figure that these flimsy 1020 trays have almost NO strength so I try to remember to keep something under them to help support the weight, before I move them or lift them. Maybe only a sheet of corrugated cardboard.
I keep planning to buy a 4x8 panel of cheap wood paneling. I could cut that up into `16 1'x2' sheets, and give each 1020 tray its own support system.
That would also keep the tray from abrading when it rubs against a rough surface, like if I take it outside to harden something off.
