The Black Anthracite® finish is a proprietary, textured duo-toned coating designed for superior corrosion resistance, making this heavy-duty shelving rack tough enough for both indoor and outdoor use. Whether it's exposed to rain, humidity, or fluctuating temperatures, the finish holds up—allowing you to confidently store items outside, in garages, or in damp areas like basements. It's also certified safe for more demanding environments like walk-in refrigerators, freezers and commercial warewashing stations. Use it to organize everything from gardening supplies and patio gear to restaurant ingredients, kitchen equipment, or bulk cleaning products. No matter where you need reliable storage, this rack is built to handle the task.
