Ballistic protection in armored vehicles is achieved through a combination of materials and systems working together to absorb and dissipate the energy of projectile impacts. Understanding how these systems work is essential for procurement teams, security managers, and defence officials evaluating armored vehicles.
Ballistic steel is the primary structural protection material. Certified plates of hardened ballistic steel are cut, shaped, and welded to the interior of the vehicle's door panels, floors, roof, pillars, and firewall. The thickness and grade of steel used determines the protection level achieved.
Armored glass, also known as ballistic glass or transparent armour, is manufactured from multiple layers of glass, polycarbonate, and interlayers bonded under pressure. The glass is fitted to all windows and the windscreen and is independently rated to the same protection standard as the steel armour.
Run-flat tyre systems ensure the vehicle can continue moving after tyre damage. Insert-type run-flat rings are fitted inside the wheel and support the vehicle's weight even with a completely deflated tyre, allowing continued operation at reduced speed until the vehicle reaches a safe location.
Protection levels are rated under the European standard EN 1063 and the German VPAM BRV 2009 standard. Ratings from B4 through B7 define the specific ammunition types and velocities that the protection system must withstand during certified testing.
Zida armored vehicles are built with certified ballistic steel sourced from approved European suppliers and armored glass meeting EN 1063 testing requirements. Full certification documentation is provided with every vehicle.
Frequently Asked Questions
What is the EN 1063 standard?
EN 1063 is the European standard for transparent armour glazing. It defines protection levels from B1 through B7, with each level corresponding to specific projectile types and velocities.
What is the difference between B4 and B6 protection?
B4 provides protection against handgun ammunition including .44 Magnum rounds. B6 provides protection against high-powered rifle ammunition including 5.56 mm and 7.62x39 mm.
