Security and Window Grilles for Schools and Colleges

Window grilles, decorative grilles, fixed grilles and more for educational premises

Harling Security is one of the leading installers in the UK of security grilles for educational premises. These are available in a wide range of configurations such as: sliding grilles, window security grilles, decorative grilles, burglar bar grilles, fixed grilles and more.

As a school, college or other type of educational establishment, there are plenty of reasons you might want a security grille to be fitted for additional security on your premises – in particular to your windows, which often act as a beacon for potential robbers or troublemakers.

Our grilles are all tailored to fit exactly where they need to, ensuring maximum levels of security for all your buildings and premises.

You might also want to consider one of our decorative grilles, to keep in with the look of your property while at the same time ensuring it remains safely protected.

As with most of our security products, all of our grilles for schools and colleges are available with security ratings, if required.

They can also be polyester powder coated to any standard RAL colour, so they match your existing colour scheme.
