Profile: C S I Shelving specializes in industrial shelving products. Our products include display fixtures and industrial shelving products. Our product line includes pallet racks, boltless shelving, cantilever rack, lockers, mezzanines, slat wall, grid wall and island & wall fixtures. Our cantilever rack is commonly used for applications where the length of the material being stored is too long for pallet rack or where the length varies. The cantilever rack allows great flexibility, for instance a 2' L run can store 8', 9', 10', 12', 16' , 20', and even longer units of product without having to deal with any columns or other obstructions. The additionally, two 8' units can be stored under two 10' units, which in turn can be stored under a 24' unit. Our supported mezzanines are commonly built using steel shelving, RivetRite, or pallet rack as the support structure. The top picture at left is a "deck over "system, meaning that the mezzanine is built on top of existing shelving. The second picture is "high density" shelving, where the only decking is between the shelving units. The posts in the high density application would be around 16 H generally, but taller posts would be used if there is a third level.
