What are the length and width dimensions of a 1.5mm stainless steel plate?
Once we have this information, we can determine the size of a mirror panel with the same thickness.

The specifications of a 1.5mm thick mirror stainless steel plate are as follows: it can have a width of 1m, 1.2m, 1.5m, 2m, and so on, while the length can vary between 1.5m and 6m.
The thickness of the mirror panel made of 1.5mm stainless steel can be either 1.2m or 1.5m.
Typically, the maximum width of a 1.5mm thick mirror stainless steel plate is 2m, and the minimum width is 1m.
Furthermore, the maximum length of a 1.5mm thick mirror stainless steel plate should not exceed 6m, while the minimum length should be more than 1.5m.
