Entrance floor system

An entrance floor system for placement in a floor recess having a recess depth, comprising:

• a base mat having a height, and opposing bottom and top surfaces, the bottom surface of the base mat configured to rest within the floor recess;
• a monolithic aluminum plate having a height, and opposing bottom and top surfaces, the bottom surface of the plate configured to rest on the top surface of the base mat, the top surface of the plate being substantially parallel with the bottom surface of the plate;
• wherein the top surface of the plate has a pattern machined therein, the pattern comprising a plurality of slots, at least one of the slots configured to receive fluid and debris;
• and
• wherein the floor system has a total height comprising the plate height and the base mat height, the total height being substantially equal to the recess depth.

An entrance floor system prepared by a process comprising the steps of:

• obtaining a floor plate design;
• converting the design into instructions readable by a computer numerical control (CNC) machine;
• operating a CNC machine in accordance with the instructions to cut, drill, or mill the design into a piece of material, thereby producing:
• a monolithic aluminum plate having opposing bottom and top surfaces, the bottom surface of the plate configured to rest on a top surface of a base mat and the top surface of the plate having a border region and a non-border region, the non-border region being substantially parallel with the bottom surface of the plate;
• wherein the non-border region has a pattern machined therein, the pattern comprising a plurality of slots, at least one of the slots configured to receive fluid and debris;
• and
• wherein the top surface of the plate in the border region comprises a transition from the floor surface to the non-border region of the top surface of the plate.
