The closest would be 18 gauge which is 1.27 mm
Metal gauge is inversely proportional to thickness, the bigger the thickness lesser the gauge. Following is conversion table:- 10 G : 3.15 MM 11 G : 2.8 MM 12 G : 2.5 MM etc....
4mm sheet metal falls 24 gauge and 25 gauge. 24 gauge sheet metal is 3.175mm (0.125") thick, and 25 gauge sheet metal is 6.35 (0.25") mm thick.
The gauge system varies depending on the type of measurement being referenced, such as wire gauge or sheet metal gauge. For example, in the American Wire Gauge (AWG) system, 1 mm is approximately equivalent to 18 gauge. In sheet metal, 1 mm is roughly equivalent to 18 or 20 gauge, depending on the material. Always check specific gauge charts for precise conversions.

Gauge and millimeters (mm) are both units used to measure the thickness of materials, particularly in the context of metal sheets and wire. Gauge is a number that represents thickness according to a specific standard, with smaller gauge numbers indicating thicker materials. The exact conversion from gauge to mm can vary depending on the material and the gauge system used (such as American Wire Gauge or Birmingham Gauge). Generally, tables are available to convert between gauge and mm for specific types of materials.
If it is steel, the thickness is 0.0359 ins (35.9 thou), or 0.9119 mm. See Wikipedia 'Sheet Metal Gauge' for a full table of thicknesses
