Superior Steel Strength

A safe’s first line of defense is its door and five walls. Door and wall steel thickness determines a safe’s ability to protect. The more steel the greater protection.

The bending strength of steel increases by approximately the square of its thickness.


  • 12-gauge (.106) steel is 2.86 times stronger than 14-gauge (.075), even though it is only .031 thicker.
  • A safe constructed of 3/16” (.188) steel is about 5.6 times stronger than one constructed from 12-gauge  (.106) steel.
  • A safe door made from 1/4” steel is 13.12 times stronger than one made from 12-gauge.


Thicker steel makes a huge difference in the protective ability of a safe. Steel is heavy and expensive but the foundation of any quality safe.
