LPS 1175 SR3 Doors


M2M3 logoCertified to LPCB LPS 1175 Security Rating 3, and available with a 240 minute Certifire rating.

Bradbury's unrivalled range of SR3 doors have undergone rigorous testing procedures, which determine their ability to withstand deliberate and pre-meditated forced entry attempts, using bodily force and a number of attack tools. For more information about how the standard of our SR3 security doors was determined, take a look at our product certification information.  

Bradbury's M2M3 range offers an extensive scope of certified steel doors, suitable for all personnel, fire exit, access control and utility applications. Doors are available inward or outward opening single, leaf and a half, and double door sets. Available with a wide range of hardware options and bespoke powder coating finishes (including a highly convincing wood-grain effect), so each door can be tailored to your needs.

For buildings that require a different level of security, we also manufacture doors that are certified to LPS 1175 SR1, SR2 and SR4.
