What is a security door? Security doors explained in simple terms!

A security door is more robust than a standard door and often features a different, more secure lock to meet higher security requirements. However, the exact specifications of a security door depend on its intended purpose. Depending on the area of application, security doors are classified into different resistance classes.

The Resistance Classes of Security Doors

Security doors are divided into five different resistance classes.

• Resistance Class 1: The door must withstand an attempted break-in by an opportunistic burglar using simple tools such as pliers or screwdrivers for at least three minutes.
• Resistance Class 2: The door must withstand a burglar using two screwdrivers or a drilling tool for at least five minutes.
• Resistance Class 3: The door must withstand an offender for at least ten minutes who uses various cutting and striking tools or a cordless drill and knows how to use them effectively.
• Resistance Class 4: The door must withstand a burglar for at least 15 minutes who attempts to open it using basic power tools.
• Resistance Class 5: The door must withstand an offender for at least 20 minutes who uses powerful power tools to break in and has extensive expertise in doing so.

For private properties such as single-family homes, apartment buildings, or high-rise residential buildings, a security door with Resistance Class 1 or 2 is usually sufficient. Most break-in attempts at private homes are carried out by opportunistic burglars, and if the door does not give way after a few minutes, most burglars will abandon their attempt.

Security doors in Resistance Classes 3 to 5 are almost exclusively installed in commercial properties, where professional burglars often target specific valuables and where there is typically much more to steal, ranging from cash and valuable equipment to products, documents, and trade secrets.
