Inner steel options have quickly become and important aspect to help manufacturers stand out from the rest. Fort Knox is probably the most prominent, with Amsec (American Security), and Edison following up in the pack. Inner steel allows for much greater strength, a good value, and flexibility in the safe you choose.

How does inner steel allow for greater strength?

Inner steel essentially creates a safe within a safe. Let’s take a Fort Knox Defender as an example, the defender series comes standard with 10 gauge steel, while impressive, it by no means is the best steel in the market.

If a standard inner steel liner is added, it creates a complete 10 gauge steel safe within the 10 gauge steel safe. This means, that if someone with a grinding wheel is able to cut a hole in the side of the gun safe, the criminal then is required to cut through a new layer of steel.

Inner steel allows for great value

Many manufacturers require if you want a greater amount of steel, a buyer needs to upgrade to a higher series of safe. Although the issue with this, is that a higher series generally means a customer is paying for a higher level of luxury. Take the Medallion series of Browning. If a customer wants the Medallion, but wants 7 gauge steel, they would need to upgrade to the Platinum Plus series.

However with this upgrade comes a more expensive interior, and other luxury options. Companies that do not offer the inner steel options don’t allow for an upgrade of steel for a minimal cost, and the customer is now required to pay for something that they never wanted in the first place.

Flexibility of inner steel

This option really does give the flexibility that is needed to give you the safe that you truly need. There are many different options of steel types to choose from to be added to your safe. Standard carbon steel is the most popular and basically creates a safe within a safe of the same steel. Stainless inner steel keeps determined thieves from cutting through the safe quickly using grinding equipment, or cutting torches, as this type of steel dissipated heat quickly, keeping the melting point low for these tools.

Of course, for those that have everything, the ballistic steel option is available. This type of steel is able to withstand blunt force hits, such as from a firearm. This is the same type of steel that is used in police bullet proof vests.


In this article we have learned what inner steel options are, and why you should make sure to think about it when you are buying your gun safe. It offers a great way to keep people from cutting into your safe, and that matters.
