When selecting a safe, it’s important to understand that its security is not only defined by its locking mechanisms but also by the materials used in its manufacture. Depending on the level of protection required, manufacturers like Arcas Gruber® use a range of specialized materials designed to resist burglary, fire, and wear over time.
1. High-Strength Steel Sheet
Steel sheet is the fundamental component in the construction of all safes. It forms the external and internal body, door panels, hinges, and locking mechanisms. At Arcas Gruber®, we use high-tensile steel to guarantee long-term durability and impact resistance. The thickness and hardness of the steel sheet vary according to the security grade of the safe.
2. Manganese Steel Alloys
Manganese steel is a hardened alloy with high resistance to drilling and mechanical attacks. It is commonly used in areas that are most vulnerable to tampering, such as around locking mechanisms, bolt work, and the core of doors. Thanks to its high tensile strength and anti-drilling capacity, it is a crucial component in certified Euro Grade safes.
3. Reinforced Concrete
Modern high-security safes often include a core made of reinforced concrete placed between the outer and inner steel walls. This multi-layer composition offers significant protection against thermal and mechanical attacks. The concrete is typically a mixture of:
- Lime
- Cement
- Sand
- Water
This material adds mass and resistance to the structure and helps absorb the energy from cutting tools and explosives.
4. Metallic Fibers
Steel fibers can be added to concrete mixtures to increase their mechanical strength and reduce cracking. These fibers work as a reinforcement element, distributing loads and resisting impact more effectively. They are frequently used in industrial-grade security cabinets and high-risk safes.
5. Fiberglass Additives
Fiberglass is another component sometimes mixed with concrete to prevent micro-cracking and to improve thermal and structural performance. While less common than steel fibers, it’s an effective choice for lighter applications where weight is a concern, such as fireproof safes.
6. Insulation Layers (Optional in Fireproof Models)
For safes requiring fire resistance, additional thermal insulation materials may be added, such as ceramic wool or vermiculite boards. These layers reduce internal temperature rise during a fire, protecting documents and electronic media.
Conclusion
The materials used in the construction of a safe determine its performance in both everyday use and in extreme situations like burglaries or fires. Arcas Gruber® carefully selects and engineers every material used in our manufacturing process to ensure maximum resistance, reliability, and certification compliance under UNE EN 1143-1 European standards.
