What are security automatic doors?
Automatic security door systems are aluminium doors designed not only to deter would-be criminals but to actively prevent theft and trespassing.
You can rest assured that nobody is walking through a high-security door that isn’t permitted to. Made with the strongest materials, and discreetly integrated with existing security systems, our exterior security doors will keep your property protected.

What kind of businesses use security door systems?
Banks & financial institutions: Automatic security doors provide controlled access to sensitive areas while ensuring a smooth flow for staff and customers. These systems are often integrated with surveillance and alarms to prevent unauthorised entry into restricted zones.
Hospitals & medical facilities: In healthcare settings, automatic security doors play a crucial role in both security and hygiene. They help restrict access to areas like emergency rooms and pharmacies while maintaining a sterile environment in high-traffic spaces.
Retail & customer-facing spaces: Combined with 24/7 surveillance, automatic doors help control access while offering a hands-free, customer-friendly experience during peak shopping hours.
Frequently asked questions
Everything you need to know about security door systems from GDUK
How does an access control system work with automatic high security doors?
Our high security aluminum doors connect directly with other control systems, which means you can monitor activity and permit entry and exit almost immediately after set-up.
Can I integrate automatic security doors with my existing security systems?
You certainly can. Our security doors are all designed and primed to be easy to use alongside pre-existing building management systems (BMS) so that you can be installed and completely secure in no time.
Cameras, flood lights, intercoms and more are supported alongside our doors, so you can install a GDUK door without the need to swap or replace any of your existing security measures.
Are automatic security doors compliant with accessibility legislation?
All of our high security door systems are fully compliant with the EN: 16005 regulation & the Equality Act, they are safe to use by people of all abilities and are not restrictive to those with medical conditions or mobility impairments.
Do automatic security doors require any regular maintenance?
In short, yes, but how often your security door system needs assessment depends on your location:
- Low-footfall areas – advised to book a service once a year
- Higher traffic and increased usage areas – should be serviced every six months
GDUK’s service and maintenance contracts can keep it in top condition, we encourage advance appointments for maintenance work but we can also come out to your property as and when required.
