Two-Tier / Multi-Tier Racking  System
This  is  designed  for  a warehouse  where  goods  are  stored  and  removed  manually  from  the shelves.  This  system  also  make  optimal  use  of  warehouse  height, as the  higher  level  can  be  accessed  manually  or  via  gangways  located between  shelves.
The  number  of  walkways  is  determined by  the  height of the shelves, bearing  in  mind  that  the  recommended  height  varies from 2.20 to 3.0 m. Likewise, the floor  of  the walkways  can  be various  types : perforated  plank, pressed  grating, closed  planks  etc.
