A cantilevered shelf between one arm and arms, efficient storage timber, pipe, long strips of material similar products. Cantilever racking, cantilever continuous through the horizontal rod, inclined rod composed of multiple cell system can be accompanied by a single column piece unit. 
 2, cantilevered shelves in the quality, safety, and management is an effective storage system. Column slices from the column and the base of the column consists of two specially designed C-shaped steel butt from this structure take full advantage of the resistance of the material load capacity, with carrying large, low cost features. 
 3, the column precast double hole, hole pitch 100mm, cantilever through the board pin connection with the column can be adjusted up and down the pitch 100mm.
