Anti-slip floor tile and method of making an anti-slip floor tile

Abstract

A floor tile is disclosed that comprises a plate having an anti-slip metal coating. The metal plate has an upper surface, a bottom surface and a plurality of edges provided on all sides of the metal plate that extend between the upper surface and the bottom surface. The anti-slip coating is applied to a central portion of the upper surface, wherein the anti-slip coating is not applied to the upper surface between the central portion and the plurality of edges. At least one recess is formed in the bottom surface that is adapted to receive a portion of an adhesive applied between the bottom surface and a floor. A method is also disclosed for making the anti-slip floor tile, wherein a metal plate is masked at a border provided around the edges of the plate and molten metal is sprayed on a central portion but not on the border.

What is claimed is: 
     
         1 . A floor tile comprising:
 a metal plate having an upper surface, a bottom surface and a plurality of edges provided on all sides of the metal plate that extend between the upper surface and the bottom surface; and   an anti-slip coating applied to a central portion of the upper surface, wherein the anti-slip coating is not applied to the upper surface between the central portion and the plurality of edges.   
     
     
         2 . The floor tile of  claim 1  further comprising:
 a recess formed in the bottom surface that is adapted to receive a portion of an adhesive applied between the bottom surface and a supporting structure. 
 
     
     
         3 . The floor tile of  claim 2  wherein the recess is one of a plurality recesses formed in the lower surface. 
     
     
         4 . The floor tile of  claim 3  wherein the recesses are cut into the bottom surface. 
     
     
         5 . The floor tile of  claim 3  wherein the recesses are embossed into the bottom surface. 
     
     
         6 . The floor tile of  claim 1  wherein the metal plate is aluminum and the anti-slip coating is stainless steel. 
     
     
         7 . A method of making a floor tile comprising:
 providing a metal plate having an upper surface, a bottom surface and a plurality of edges provided on all sides of the metal plate that extend between the upper surface and the bottom surface;   masking a border on the metal plate the upper surface between the central portion and the plurality of edges; and   spraying molten metal on the central portion of the metal plate to form an anti-slip coating on the central portion but not on the border.   
     
     
         8 . The method of making a floor tile of  claim 7  further comprising:
 grit blasting the central portion of the metal plate after the masking step and before the step spraying molten metal. 
 
     
     
         9 . The method of making a floor tile of  claim 7  further comprising:
 cutting at least one groove in the bottom surface of the metal plate that is configured to receive a portion of an adhesive applied to the bottom surface and a supporting structure. 
 
     
     
         10 . A floor tile comprising:
 a metal plate having an upper surface, a bottom surface and a plurality of edges provided on all sides of the metal plate that extend between the upper surface and the bottom surface;   an anti-slip coating applied to the upper surface; and   a plurality of grooves provided in the bottom surface.   
     
     
         11 . The floor tile of  claim 10  wherein the plurality of grooves extend across the bottom surface. 
     
     
         12 . The floor tile of  claim 10  wherein the plurality of grooves extend across the bottom surface of the metal plate and intersect with others of the plurality of grooves. 
     
     
         13 . The floor tile of  claim 10  wherein a plurality of recesses are formed on the bottom surface of the floor tile. 
     
     
         14 . The floor tile of  claim 10  wherein the anti-slip coating is applied to the upper surface at a location spaced from the plurality of edges.
