This 14" x 30" Galvanized Steel Louvered/Embossed Metro Shelf is a good choice for dry storage due to its minimal corrosion resistance. These shelves feature a 1/8" 'ship's edge', epoxy coated corners and the louvered/embossed style promotes air circulation. Galvanized shelves feature uncoated cast corners that are ideal for applications requiring a minimum resistance to corrosion. Super Erecta shelves accept Metro's 1" diameter posts, and feature a split sleeve adjustment, making them easy to precisely position in 1" increments along the grooved and numbered posts.
