These days, reinforced door sets are the most effective solution for bolstering the security of at-risk buildings such as offices, public institutions, industrial sites, military sites or high-risk zones.
The technical design of these solutions, combining mechanical robustness and advanced locking technology, guarantee reliable protection against intrusion, explosions, and fire.
But how do you choose the right model for your project? SERSYS, the French manufacturer of certified security solutions, guides you through the key points.
What are the different types of reinforced door sets?
Each site comes with specific security constraints. That’s why SERSYS designs and builds a number of ranges of reinforced door sets suited for different levels of protection.
Bulletproof door sets
Designed for at-risk sites like banks, police stations, diplomatic or military buildings, these models offer EN1522 certified ballistic resistance.
They provide effective protection against gunshots thanks to their multi-layer composite materials and high-density steel reinforcements.
Break-in resistant door sets
Ideal for industrial sites, offices, secure depots, or restricted zones, these door sets are tested under EN1627 and the French NF A2P standards.
Their design blocks all attempts to force, drill, or pick the locks.
For example, the TECHLOCK+ RC4 or A2P RC4-class models combine exceptional mechanical resistance with simple integration with access control systems.
Fire rated door sets
Intended for public-access buildings and hospitals, these solutions provide an effective barrier to the spread of flames and smoke.
Certified under the European EN1634 standards, they guarantee protection of people and infrastructure while maintaining SERSYS high-performance safety.
What are the key criteria for choosing?
Certifications
Above all, verify official certifications:
-
A2P (Assurance Prévention Protection – Insurance, Prevention, Protection) for resistance to break-ins;
-
CNPP for conformity to security standards;
-
CETIM for mechanical robustness;
-
EFECTIS for fire rating standards;
-
BNE for bulletproofing standards.
These badges guarantee the reliability and manufacturing quality of the product.
The security level
Choose a door set that suits your level of risk:
-
Standard for administrative or office buildings;
-
Reinforced for public buildings and technical areas;
-
High risk for sensitive environments like military, luxury retail, data centres, laboratories.
The SERSYS TECHLOCK+ and ELECTRE+ or NEXUS solutions allow you to build a bespoke solution that fits your needs.
Materials and design
A good reinforced door set combines:
-
Drill-resistant steel sheets;
-
Options for fire resistant insulating core;
-
Motorised electromechanical locking;
-
Reinforced hinges or security pivots.
This combination ensures optimal resistance, durability, and ergonomic usage.
Advice for making the right choice
-
Evaluate your security needs. Identify the areas that are critical to protect (server rooms, archives, treasuries).
-
Prioritise certified and scalable solutions. SERSYS door sets are designed to integrate easily into access control, CCTV, or central management systems.
-
Don’t skip the aesthetics. SERSYS offers multiple customisable options (colours, handles, finishes in stainless steel or lacquer) to combine security and architectural design.
-
Reach out to qualified installers. The quality of the installation has a direct effect on the level of protection provided.
