Collapsible grilles, once locked, are extremely strong and will deter any potential intruder. With one of Surrey’s widest selections of finishes, and an inherently adaptable design, Costello Security Installers has a comprehensive range of collapsible grille options for any home, office, retail or catering environment.


Supreme protection, with added flexibility

The strength of our collapsible bar grilles, security mesh grilles and bar grille doors provide your premises with comprehensive  protection against intrusion, criminal damage, vandalism and theft.

They can well be hidden by using curtains or other soft furnishing and slide out of the way easily and discreetly when not in use.


Free consultation and advice as standard

Before you choose any of our compact and cost-effective collapsible grilles, please feel free to browse the wide range of options available to find out which one matches your security requirements.

If you are unsure as to the best means of installation to secure your particular property, more than two decades of experience lends itself to our expert security advice and assistance. Remember, we offer you a no obligation survey and quotation for free.
