Hi-Tech metal shelving systems include a multitude of components and options for customizing down to the last detail. Standard-post units are available in OPEN or CLOSED types as well as starter and adder units. Each Hi-Tech metal heavy-duty shelf has a tubular welded box beam in front and rear for maximum strength, exclusive triple bend side flanges for even more strength, lapped and welded corners, and the shelves are punched to accept shelf dividers. Each shelf is installed using only 4 shelf clips and can be installed together with both beaded front and angle back posts as well as T-posts and H-posts. Hi-Tech Steel Shelving is perfect for most medium-duty and heavy-duty product, tool and gear storage.
