Over 25 Years of Bradbury

Founded in 1991, Bradbury Group started out as an independent local company, originally named Bradbury Security Grilles, which specialised in the manufacture of window grilles. Bradbury Security Grilles went on to partner with and acquire several independent companies with a similar purpose and values to ours, which led to us changing our name to Bradbury Group.

Bradbury Group has since grown into one of the UK’s leading manufacturers and suppliers of innovative physical security solutions to keep the nation’s businesses and infrastructure safe. Our Group companies, Bradbury Security, Martin Roberts, Newton Security Doors, and Extendor, have enabled us to increase our offering, not only in products but also expertise and services.

Now, with over a quarter of a century of experience, we have developed a workforce of industry experts, with the ability to provide exceptional technical knowledge, and highly specified products. Having supplied solutions to some of the world’s most prominent and prestigious brands, Bradbury Group is recognised globally as a leading supplier of steel doors and physical security solutions.

    Paul Pollard, WG Pollard
  • “We’ve been working with Bradbury Group for many years on the WPD contract, and have always got great service and product from them, which is essential for us at T&A Maintenance when securing these critical infrastructure sites.”

    David Atkinson, Director, T&A Maintenence

    Mick Marshall, Director, MDM Security Doors
  • "I have used Bradbury Group for M2M steel doorsets for several years and will continue to use them because of the fantastic build quality, excellent powder coating finish and ease of fitting.
