Panels and support bases are molded into one piece at a time. The support base features a checkered pattern, with the top surface reinforced by arched ribs that intersect. The bottom and top sides are nested together to form a single unit, reinforced with screws for enhanced fit. The design allows for four-way forklift access, making it suitable for stacking and racking. For easy transportation, the top and bottom can be separated for shipment, saving space and transportation costs.
