FORMER GERMAN SUBMARINE TYPE XXI
 
 
 
 
DECK COVERINGS
 
 
 
 
SUMMARY
  
     
          Wood decking is employed only on the bridge, and in the radio and sound rooms.  Wood gratings are fitted in the refrigerator and in the magazine.  
          Linoleum, although specified for living quarters and torpedo room, is eliminated.  In walkways, woven cocca matting is provided in the absence of other deck covering.  
          Tile is provided on the galley, washroom and heads.  
          Warts of deposited weld material provide a non-skid surface on the superstructure deck, and at inboard locations where such surfaces are considered necessary.  Diamond plates are provided in the engine room.  
          The type 21, while it generally extends the use of the weld deposit type of non-skid decking, and eliminates linoleum, presents no departure in principle from earlier types, and further research is accordingly not indicated.
