trongroom Door Thickness Explained – How Thick Should It Be?
What thickness should a strongroom door be?
The thickness of a strongroom door depends on the level of security required.
Typical ranges include:
- 6mm–10mm steel plate → standard commercial use
- 12mm–20mm steel plate → high-security environments
Thicker doors provide greater resistance to cutting, drilling, and forced entry.
Why does thickness matter?
Steel thickness directly affects:
- Resistance to mechanical attack
- Structural strength
What is considered a high-security strongroom door?
A high-security strongroom door typically includes:
- 12mm–20mm outer steel plates
- Reinforced frames and hinges
- Advanced locking mechanisms
These features provide maximum protection against forced entry.
Does thicker always mean better?
Not always. The correct thickness depends on:
- Risk level
- Type of assets stored
- Budget considerations
How is a strongroom door constructed?
A typical strongroom door includes:
- Outer steel plate (6mm–20mm)
- Internal reinforcement
- Multi-bolt locking system
- Heavy-duty frame with mounting lugs
This layered construction provides strength, durability, and resistance to attack.
What thickness is recommended for different applications?
- Offices and general business use → 6mm–10mm
- Retail cash handling → 10mm–12mm
- Banks and high-value storage → 12mm–20mm
