Low-profile interlocking plastic dunnage racks sit closer to the ground than other styles of dunnage racks. Multiple racks can be connected to expand the surface area of the racks. These plastic racks weigh less than metal racks and will not rust when used in wet environments or areas where the racks will be washed down often. They have a grid top with openings that allow liquids to drain away from the racks and let air circulate through the racks for ventilation.

Aluminum dunnage racks are lightweight and will not rust when used in wet environments or areas where the racks will be washed down often. The racks have a slatted deck with gaps that allow liquids to drain away from the racks and let air circulate through the racks for ventilation. All parts of the racks are welded together for strength. They provide a smooth surface that will not snag bags or leave indentations on products.

Wire dunnage racks provide more protection against small or irregularly shaped items falling through the racks than dunnage racks with slatted decks. These racks have a wire deck with openings that allow liquids to drain away from the racks and let air circulate through the racks for ventilation.
