These commercial grade carts feature top grade steel, oversize casters, and easy assembly. When you have a lot of wall board, drywall, paneling, or plywood to move in and out of tight spots, this is the cart to have on your team. You can load up to 1600 lbs. on this commercial grade cart. We are talking heavy-duty 8-wheels that will make this the smoothest rolling cart even when fully loaded.
