Bullet-resistant components are used in public institutions, by the police or by people who require appropriate protection.

There are a large number of categories for bullet resistance, which are necessary due to the different weapons and calibres.

The components are tested in standardised procedures in test laboratories. Special ballistic devices are used for ballistic testing. The firing device is used to shoot at defined points on the component.

TPO Holz-Systeme can manufacture bullet-resistant components.
