Not every safes are developed equal.

You are watching: Which is thicker 12 or 14 gauge steel

Door and wall steel thickness identify a safe’s capability to protect. The an ext steel, the greater protection. Please review the complying with graph.

The graph illustrates a general ascendancy of steel strength. The bending stamin of steel rises by about the square of its thickness. 

12-gauge (.106) stole is 2.86 times more powerful than 14-gauge (.075), also though it is only .031 thicker.A safe constructed of 3/16” (.188) stole is around 5.6 times more powerful than one constructed from 12-gauge (.106) steel.A safe door do from 1/4” stole is 13.12 times stronger than one do from 12-gauge.

Thicker steel renders a large difference in the protective capacity of a safe. Stole is heavy and also expensive but it is additionally the foundation of any kind of quality safe.


STEEL — A Safe’s first Line the Defense

A safe’s an initial line that defense is its door and wall surface construction. The lot of stole in a safe’s door and also five walls determines that strength. The more steel used, the higher its protective ability.

The advantage of extra steel thickness is periodically not totally understood or appreciated. A general dominion of steel toughness is the it rises by the square the its thickness. If you twin the thickness that a piece of steel, that is not simply twice as solid but surprisingly roughly eight times together strong.

A for sure door make from 1/4″ (.250) stole is end nine times more powerful than one make from 11-gauge (.120) steel. A door do from 10-gauge (.135) steel is over double as solid as one do from 12-gauge (.106) steel also though that is only .029 more thickness (see Steel stamin Chart). Thicker steel can make a vast difference in the protective capability of a safe.

When considering a safe, look at the lot of steel provided in its construction. Exactly how thick is the steel offered in the body? go it have actually a stole reinforced door casement? A top quality safe will have a stole reinforcement roughly the door opening.

Door construction is especially critical since that is usually the very first point the attack. Is the door formed from thin steel bent come look thick? exactly how thick is the outer door steel? walk the door save on computer a full second piece of within door steel?

Most of safe Guard’s competitors utilize doors created from one class of thin steel (12-gauge or less) developed to watch thick. Door edge thicknesses of one to 2 inches room common. These stole deficient hole doors are sometimes filled through sheetrock or partial piece of inner door steel. Numerous of this doors room visibly impressive but lack the steel to provide foundational rigidity. Don’t be fooled by thick appearing hollow doors even if they carry impressive national brands. Placing a renowned brand on a steel deficient for sure does not enhance its security.

When it concerns providing security, over there is no substitute because that steel. The more steel used, the greater the security.
