Organize your home, office or garage with this Seville Classics 5-Tier Shelving System. This versatile shelving unit is constructed from industrial-strength UltraZinc plated steel. The zinc-plating process provides added corrosion resistance and is better for the environment (compared to chrome plating) as fewer harmful chemicals are used in the plating process. Each ventilated shelf has a weight capacity of up to 600 pounds (on adjustable leveling feet) and the entire shelving system can hold 500 pounds on wheels. Shelves can be adjusted at one-inch intervals and are compatible with other Seville Classics branded shelving of similar sizes and configurations. This durable shelving system is the ideal storage solution for organizing any room.
