We provide the installation, maintenance and repair of security grilles.

Security grilles are a simple, effective way of defending and protecting your business from issues such as burglary and vandalism. Unlike full shutters, grilles offer a line of sight so potential customers can still view your premises and window displays. At Royal Industrial Doors we make grilles in a range of finishes, can fit them both inside and outside and design them to fold in when not required. Our grilles are bespoke manufactured to your measurements.

For specification information, installation and aftercare, get in touch to arrange a free site survey.

Security grilles give you security

We set high standards and install grilles that are durable. Our security grilles are manufactured using high grade steel and the protective coatings used can protect against harsh environments. The bespoke sized construction guarantees a perfect fit that prevents gaps. Because the panels are collapsible, they can be opened during opening hours and remain secured when you need them.

After installation our engineers carry out a report and advise on a maintenance plan that extends the life of the grilles and helps keep your building safe. We supply security grilles to commercial and industrial clients across Luton, Stevenage, Milton Keynes and the wider surrounding areas.

Frequently Asked Questions

What are security grilles?
Security grilles are external barriers custom fitted to shops or buildings. Constructed from strong, corrosion-resistant steel and finished in a range of colours, they defend against burglary and vandalism while allowing light and partial vision through the window. Options include manual or electric operation, with secure locking.
What are the benefits of security grilles?
Security grilles offer protection without completely obscuring your premises. They deter theft, reduce the risk of vandalism and help maintain the appearance of your building. Built to bespoke sizes, they fit perfectly to minimise gaps and common attack points. Depending on your requirements, grilles can be lightweight for manual use or motorised for convenience, and the protective finish can be matched to your building colours or branding.
Where can I purchase security grilles?
Royal Industrial Doors supplies security grilles directly to businesses across the UK. Speak to our sales team to arrange a site survey; we will manufacture your bespoke grilles, install them and provide aftercare.
How are security grilles installed?
Installation begins with a site survey and precise measurements. Our engineers fit mounting brackets and frames, assemble the panels, apply corrosion-resistant coatings and connect any electric drives if specified. Once complete, we commission and test the system, supply a report and provide user training. A scheduled maintenance plan and optional 24/7 emergency call-out ensure your security grilles remain functional and effective for years.
