         2 . A floor according to  claim 1 , wherein the base element is connected to a head being substantially parallel with and offset relative to the base of the floor section, wherein the two side walls are parallel with each other. 
     
     
         3 . A floor according to  claim 2 , wherein a transition portion is formed and located between the head and the two side walls. 
     
     
         4 . A floor according to  claim 1 , wherein the base element is connected to a head being offset relative to the base of the floor section, wherein the two side walls are concave relative to one another. 
     
     
         5 . A floor according to  claim 1 , wherein each of the protruding elements extends in a first direction of said floor section and the distance between two side walls being at least 1 mm and the distance being at least 10 mm. 
     
     
         6 . A floor according to  claim 1 , wherein the base includes a first end and a second end positioned opposite the first end, wherein the first end of the base is elevated relative to the base and being configured for engaging a corresponding second end of another floor section. 
     
     
         7 . A floor according to  claim 1 , wherein the protruding element is formed by a roll forming the sheet material into a number of floor sections including a number of protruding elements. 
     
     
         8 . A floor according to  claim 1 , wherein each floor section has protruding elements being arranged in more than one row. 
     
     
         9 . A floor according to  claim 1 , wherein the floor section forms an air duct for transporting a cooling air in each floor section of the container. 
     
     
         10 . A floor according to  claim 1 , wherein the single sheet element is metal sheet, preferably high grated stainless steel. 
     
     
         11 . A container comprising a floor part, an end wall, a roof lining forming a ceiling, two opposite side walls and a floor according to  claim 1 , wherein the floor is connected to each of the opposite side walls and an inner compartment being formed between the floor part and the floor, wherein the inner compartment formed by the floor part and an underside of the floor is adapted to be filled with an insulation material. 
     
     
         12 . A floor section for a container floor, the floor section being formed from a sheet element and having a rectangular shape with a length extending in a first direction and a width extending in a second direction being perpendicular to the first direction, the floor section comprising:
 a plurality of protruding elements extending from a base; wherein each protruding element extends longitudinally in the first direction and comprises:
 a head; and 
 two side walls connected between the base of the floor section and the head; 
 wherein the head extends in the second direction by a first distance and at least a portion of the side walls extend in the second direction by a second distance and the first distance is greater than the second distance; 
   wherein an air duct is formed between the base, the heads, and the side walls of two neighbouring protruding elements and is arranged to guide an air flow within the air duct.   
     
     
         13 . A method of manufacture of a floor section for a container floor comprising:
 providing a sheet element and having a rectangular shape with a length extending in a first direction and a width extending in a second direction being perpendicular to the first direction   forming a plurality of protruding elements extending from a base; wherein each protruding element extends longitudinally in the first direction and comprises:
 a head; and 
 two side walls connected between the base of the floor section and the head; 
 wherein the head extends in the second direction by a first distance and at least a portion of the side walls extend in the second direction by a second distance and the first distance is greater than the second distance; 
   wherein an air duct is formed between the base, the heads, and the side walls of two neighbouring protruding elements and is arranged to guide an air flow within the air duct.
