Have you ever wondered if those massive shipping containers, often seen on cargo ships and trucks, are bulletproof? It is a question that may not come up in everyday conversation, but it is surprisingly relevant in situations where safety and security are critical. 

In this article, I will dive into the fascinating details of what shipping containers are made of, primarily focusing on corten steel, known for its strength, durability, and unique rust-resistant properties, to find out whether shipping containers are bulletproof or not.  

What are Shipping Containers Made Of?

Shipping containers are predominantly constructed from a specific type of steel known as Corten steel. This material is chosen for its impressive combination of strength, durability, and remarkable corrosion resistance, which it achieves through rust patination. The corrugated wall panels, frames, and cargo doors of these containers all utilize this robust steel​​​​​​. 

Contrary to what one might assume, the floors of shipping containers aren’t made purely of steel. Instead, they comprise a wooden foundation topped with metal paneling. This design choice provides a balance of strength and flexibility, essential for maneuvering goods within the container​​.

The primary function of shipping containers is to transport goods, not to act as bulletproof barriers. That being said, the Corten steel construction does offer a certain degree of bullet resistance, varying with the type of ammunition used. 

Tests have indicated that these containers can resist lower caliber bullets, like.22LR and shotgun pellets. However, more potent ammunition, such as a full metal jacket or armor-penetrating bullets, can breach their defenses. 

The efficacy of a shipping container against bullets, therefore, is not absolute but rather dependent on the type of ammunition.

How Can Containers Be Modified to Increase Bullet Resistance?

To enhance their bullet resistance, a process known as “hardening” is employed. This involves adding additional layers of metal or ballistic materials, like Kevlar or ceramic plates, to the container walls. 

Common choices for this purpose include steel plates, which are effective in absorbing the energy of a bullet and reducing penetration likelihood. It’s crucial to note, however, that even with such modifications, shipping containers cannot achieve complete bulletproofing. 

They become more resistant to gunfire but can still succumb to high-powered rounds or sustained gunfire. The level of hardening should be tailored to specific security needs, considering that standard containers are adequate for most situations, but higher-risk settings might necessitate further reinforcement​​.

Applications for Bullet Resistant Shipping Containers

Shipping containers, when modified to withstand bullets, can be utilized for a variety of purposes in addition to transporting goods. 

They become invaluable in both military and civilian contexts:

  • Military and Security Applications:
    • Project Offices
    • Border Crossing Points
    • Munitions Storage
    • Security Guard Rooms
    • Surveillance Stations
    • Military / Police / Security
  • Civilian Applications:
    • Server Farm Entry Points
    • Safe Havens
    • Secure Communications Rooms
    • Dangerous Chemical Storage
    • Panic Rooms
    • Bunk Houses / Secure Sleeping Areas

These modified containers can seamlessly integrate into various environments, offering secure spaces in potentially hazardous situations​​.


Standard shipping containers are not inherently bulletproof, but their construction does offer some level of bullet resistance. This resistance can be significantly enhanced through hardening processes employing additional layers of metal or ballistic materials. 

The resulting bullet-resistant containers thus serve a broad spectrum of applications, catering to both security needs and civilian safety requirements. Their versatility and adaptability make them a unique solution in scenarios where bullet resistance is desired or necessary.
