How Our Protective Screens Work

Smart Protection. Simple Design.

Safer Environment Through Reliable, Visible Protection

Strong security begins with solutions that are properly specified, independently tested and proven to perform. When people can clearly see that their environment is protected by certified systems designed to meet defined performance levels, it builds confidence in the space around them.

This visible assurance helps create a setting where users feel safe, supported and comfortable.

EXCELLENT LIGHT TRANSMITTANCE OF 80%

Perforated benefits by CrimeScreen

Strong Physical Barrier

CrimeScreen´s perforated steel inserts are made from 2 mm thick solid steel sheets punched with holes, and yet, highly resistant to cutting, prying, and impact damage.

Corrosion-Resistant

CrimeScreen´s perforated steel inserts are electro-zinc plated (typically 2.5 to 5 microns thick) prior to in-house powder coating making them ideally suited for outdoor use, as both the perforated steel insert & aluminium frame are resistant to rust & and weather damage.

Security + Visibility

Perforated steel inserts allow excellent airflow-through whilst allowing good visibility and acting as an excellent protective barrier—so you don’t have to sacrifice light or ventilation for security & safety.

Low Maintenance

Requires minimal upkeep—typically just occasional cleaning to remove everyday dirt & grime, whilst protecting the glazing behind from becoming dirty.

Light In Weight, But Heavy In Security

CrimeScreens with perforated steel inserts add only a light additional weight loading to the window & door frames that our CrimeScreens are fitted onto.

Easy Replacement

If the perforated inserts are attacked and damaged, replacement on site is easy, economic and quickly done by our fully trained fitters.
