I put this sheet of 1" steel in the bed of my truck to use as extra weight when I plow snow, and protection for the floor from heavy wood. I tapped some 1/2" holes in it so I can pick it out with the fork lift if I need to in a hurry. Also added some turnbuckles to help hold in place. It wasn't moving around on the bedliner until the freezing weather got here. I suspect some water froze underneath of it and made it slick. I use to put tractor weights in the back for plowing snow, but it was such a cluster trying to use the truck for anything else with them sticking up. The sheet of 1" weighs 1,306 lbs and works perfectly.
