This four-tier steel shelving unit trades shelf count for extra strength per level, with each of its four shelves rated to hold up to 600 pounds and a combined capacity of 2400 pounds. That suits heavier items like power tools, paint cans, or boxed equipment in a garage or warehouse without worrying about sagging shelves. The SPCC carbon steel frame has a powder-coated orange finish that resists rust and scratches while standing out against typical gray garage walls. Shelf height adjusts to fit taller equipment on one level and smaller bins on another, and side board hooks let you mount extra grid plates for hanging storage. Assembly is a press-to-install design that skips drilling. The split frame also fits low-clearance spaces such as under stairs or a basement. At 20 inches deep, 40 inches wide, and 60 inches tall, it suits kitchens and basements too.
