Quardian® is a steel that provides resistance to ballistic impact and explosions. Its advanced protection capabilities are validated by numerous independent and accredited laboratories. Quardian® is produced in Belgium by NLMK Clabecq, whose expertise in rolling thin steel plates has been recognised for many years.

Quardian® ballistic properties are the result of specific chemistries developed in house, a unique process rolling and quenching and tempering treatments in our ultra-high-performance facilities. The different proposed combinations of hardness and tensile strength ensure that you will always find the Quardian® adapted to your desired protection.

The unique layout of the rolling mill, along with the modernity and the technicality of the Quenching & Tempering unit , and the quality of the slabs, all combine to produce steel plates with exceptional thickness tolerances, surface finish and flatness. These characteristics give it the advantage of being easily workable. To ensure that Quardian® is compliant with different international ballistic standards, NLMK Clabecq conducts numerous tests in independent laboratories, which are recognised worldwide. So when you use Quardian®, you can be sure that everything has been done to make you feel safe.

The most widely used standards that define the resistance of our steels are (among others)*:

• EN 1522 (FB2 - FB7)

• VPAM (L6 - L9)

• STANAG 4569 AEP-55

• NFA 36800

• MIL-DTL-46100E

• ABNT 15000

It is easy to take advantage of the superior workability of Quardian®: at every processing stage (cutting, bending, welding or machining), its performance contributes to increase your productivity. It also opens the door to new, more efficient, designs...

NLMK Clabecq engineers are always at your service to provide the right Quardian® to match your specific requirements.
