For doors exposed to heat up to 1000 degrees Fahrenheit, a good gauge of steel would typically be at least 14 gauge (0.0781 inches thick) or heavier, such as 12 gauge (0.1046 inches thick). Thicker steel provides better structural integrity and resistance to warping or deformation under high temperatures. Additionally, using steel that is specifically designed for fire-rated applications can enhance safety and performance.
