It's just a metal drawer that's mounted to some ball bearing sliders. It's going into a cart. Yeah, I thought about plug welding it, but wasn't sure if the weld would adhere to the slider or not. Not sure if the slider is galvanized or what it is. The picture is poor quality, but you can see the rivets sticking out inside the drawer.
