This Metro Super Erecta shelf is 18" x 24" and features two‐fold thickness of 18‐gauge steel that forms 1/8" raised edges on all four sides of the shelving. It has uncoated cast aluminum corners and is ideal for applications requiring solid shelving or a work surface and minimum resistance to corrosion. This solid shelf can be adjusted in 1" intervals along the post for more storage versatility. It can also be loaded and unloaded from all sides for added convenience.
