Excellent repair and universal sheets. Although there is no weight load, they are extremely stiff and very durable. Be sure to use screws with washers to avoid paint chipping, especially when there is moisture around them. I've used them to reinforce part of my workbench and to reinforce a bag rest I made for the back of my mower. In the second example I sanded it down with 400 grit sandpaper and painted it black and so far it has held up well. They are very handy to have on hand and the 10 pack allowed me to add a few extras for future projects.
