## Abstract

An embodiment of a metallic table constructed with a Non-Flammable Substrate 101 used as the internal structure for a Metallic Table Top 201, including a Metallic Table Apron 301. The Metallic Table Apron 301 may be joined to the Metallic Table Top 201 by welding, brazing, or other methods without causing damage or ignition to the Non-Flammable Substrate 101. The Metallic Table Apron 301 increases the visible thickness and decorative variety of a metallic table for decorative purposes without obtrusively increasing the weight or manufacturing cost of a metallic table.

## Claims

### Claim at position 1

1-4. (canceled)

### Claim 5

A table top, comprising:
sheet stock, formed of a first material, applied over a substrate, formed of a second material, so as to form a table top;
the first material is a metal; and
the second material is different from the first material and is non-flammable and resistant to heat applied to the sheet stock, such as from welding or brazing.

### Claim 6 (depends on 5)

The table top according to claim 5, wherein the second material is magnesium oxide fiber board.

### Claim 7 (depends on 5)

The table top according to claim 5, wherein the sheet stock includes edges extending between a top and retention lips that together are applied over and hold the substrate.

### Claim 8 (depends on 7)

The table top according to claim 7, further including a metal apron depending downwardly from the retention lips.

### Claim 9

A method of manufacturing a table top, comprising:
providing sheet stock formed of a first material;
providing a substrate formed of a second material different from the first material; and
forming the sheet stock over the substrate so as to form a table top, wherein the first material is a metal, and the second material is non-flammable and resistant to heat applied to the sheet stock, such as from welding or brazing.

### Claim 10 (depends on 9)

The method according to claim 9, wherein the second material is magnesium oxide fiber board.

### Claim 11 (depends on 10)

The method according to claim 10, wherein the step of forming the sheet stock over the substrate further includes folding the sheet stock over the substrate so as to form in the sheet stock edges extending between a top and retention lips that together are applied over and hold the substrate.

### Claim 12 (depends on 11)

The method according to claim 11, further comprising attaching a metal apron to the retention lips via the application of heat, such as by welding or brazing, and the substrate withstanding said heat so as to resist burning, wherein the apron depends downwardly from the retention lips.
