Heavy-Duty Freestanding Wire Shelving Unit (4/5-Tier Options) Build quick order in your garage, pantry, basement, laundry room, workshop, or backroom with an inparticlesrial-style metal storage rack engineered for real weight. The thick carbon steel frame features a durable black anti-rust coating, while dense open-wire shelves help disperse load and keep stored items cleaner and drier. Serious strength, reinforced to resist sagging: up to 440 lbs per shelf .Each tier is supported by three V-shaped reinforcement ribs to reduce bending and long-term deformation. Adjustable shelf height, custom fit storage: evenly spaced slots on the posts let you move each shelf up or down to fit tall bottles, stacked pans, storage bins, bulk supplies, toolboxes, or small appliances. Stable on uneven floors: includes non-slip leveling feet for steadiness on garage or laundry room floors; a wall-fixing kit is included for added anti-tip safety when needed. Fast boltless, tool-easy assembly: designed for quick setup with included accessories and clear instructions—most users finish in about 10–15 minutes. Use it anywhere: as garage shelving for tools and tires, a pantry organizer for canned goods and appliances, a basement storage rack for seasonal items, or commercial shelving for warehouse, office, or retail inventory. For best stability, place heavier items on the lower tiers.
