It's all welded construction makes it easy to move around and adjust. The top plate is swaged on and rotates to adjust. It's made from 1/4 inch steel plate. I've used other jack stands but this is the type I'll always use from now on. I drug 4 of these through the dirt under a house and they still operated easily. This is not a lifting jack. The turn bar is for adjusting, not turning to lift. It can bend if you push hard enough. You need to jack up the beams first and use this to support the weight. You get what you pay for. Well worth the money.
