When transporting mixed loads of Construction materials such as light fixtures, hand tools, and bulk Hardware, properly separate items by weight and fragility on each pallet. Load heavy, dense construction goods at the bottom, with lighter cartons of LED lights on top, and add corner boards, top sheets, and stretch wrap to stabilize the load.
