Certified Steel Doorsets
Security rated steel doorsets are now a standard requirement for many commercial and industrial buildings in the UK. Insurers, consultants and police backed schemes increasingly insist on external doors that are not just strong, but independently tested and certified to recognised security standards. A true security rated doorset gives you measurable, documented resistance to forced entry and a clear level of protection you can specify and insure against.
Samson Doors supplies a wide range of LPS1175 tested and certified steel doorsets from leading UK and European manufacturers. All doors are made to measure, factory assembled as complete doorsets and available with ratings such as SR2, SR3 and SR4, as well as STS 202, PAS 24 and European RC classes. Many models are insurance approved and recognised under the Secured by Design “Police Preferred Specification” scheme.

Why a security rated doorset is different
A security rated steel doorset is very different from a basic “security door” with a heavy skin and a good lock. Rated doors are LPS1175 tested or certified to other recognised standards as a complete unit. The leaf, frame, hinges, locks, cylinders, fixings, vision panels and louvres are all included in the test build. Independent test houses then carry out controlled attacks with defined tool sets and time periods. The door either meets the security rating or fails.
This approach gives you:
- Third party certified performance rather than marketing claims.
- Insurance approved doorsets that align with specific policy conditions.
- A common language of SR2 rated, SR3 rated and SR4 rated doors that architects, security consultants and clients understand.
For many projects, especially those in higher risk sectors, a properly specified, security rated steel doorset is now seen as the only acceptable solution where genuine high security is required.

LPS1175 tested security doorsets
LPS1175 is one of the most widely used standards for security rated steel doorsets in the UK. As a Loss Prevention Standard it sets out how doors must be tested, which tools can be used in each test level and how long the door must resist attack. Under the current Issue 8 format, security ratings combine tool categories and attack times, but most specifiers still talk in terms of SR1, SR2, SR3 and SR4.
For security rated steel doors, the most relevant levels are:
- SR1 (A1): Protection against opportunist attack with small, easily concealed tools, suitable for lower risk sites and as a basic security level.
- SR2 (B3): SR2 rated doorsets are designed to resist more determined attacks for at least three minutes of sustained tool use with items such as larger screwdrivers, levers and small drills. SR2 security rated doors are often specified for offices, schools, small shops and medium risk commercial properties.
- SR3 (C5): SR3 rated doors withstand five minutes of deliberate attack using a wider range of heavier hand and cordless tools such as crowbars, short axes and cordless drills. These high security doors are chosen for more exposed entrances, higher value contents and increased risk locations.
- SR4 (D10): SR4 rated doors are at the very high security end of the spectrum for commercial and industrial use. They are built to resist ten minutes of intensive attack with heavy tools including sledgehammers, felling axes and powerful cordless tools. SR4 rated steel doorsets are typically used for critical infrastructure, high value storage and sensitive government or defence sites.
Specifying an LPS1175 tested and SR2 rated or higher steel doorset ensures that your door has been independently proven to withstand real world attack methods for a defined period of time.
Other security ratings (STS 202, PAS 24 and EN 1627)
Alongside LPS1175, several other security standards are relevant when you are choosing high security or insurance approved steel doors.
STS 202 is a UK burglary resistance standard that grades doorsets as BR1 to BR6, using similar controlled attack tests to LPS1175. Lower BR ratings focus on opportunist attacks with small tools, while BR3 and BR4 address more determined attackers using heavier hand tools. BR5 and BR6 move into very high security territory with extended attack times and more capable tools. Many ranges carry both LPS1175 and STS 202 certifications.
PAS 24 is a British standard that defines minimum security performance for doors and windows in dwellings and certain mixed use buildings. It is a pass or fail test that focuses on resisting forced entry by an opportunist burglar. PAS 24 rated steel doorsets are commonly required under Building Regulations for new residential developments, and many of these doorsets also carry Secured by Design approval.
EN 1627 defines European RC (resistance class) ratings from RC1 to RC6. RC2 and RC3 are most frequently specified in the UK, particularly on projects with European architects or multi national clients. Some steel doorsets are certified under both UK and European schemes, for example as LPS1175 SR2 rated and RC3 at the same time.

Secured by Design and insurance approved doors
Secured by Design is the official police initiative that recognises products which can demonstrably reduce crime. A steel doorset with an LPS1175 or PAS 24 rating which also meets Secured by Design criteria will often carry the “Police Preferred Specification” badge. This is a powerful reassurance for building owners, specifiers and insurers that the product is genuinely security rated and has been tested to independent standards.
For many insurers, using an LPS1175 tested and security rated door from a recognised manufacturer is a condition of cover at higher risk sites. Choosing an insurance approved and security certified doorset from the outset reduces the risk of disputes in the event of a claim after a break in.
Ranges available from Samson Doors
Samson Doors can supply a wide selection of security rated steel doorsets to suit different projects, from medium security SR2 rated doors for commercial and residential buildings, through to very high security SR4 rated doorsets for critical infrastructure and high value assets.
SecurGuard and SecurGuard+ doorsets
The SecurGuard range offers LPS1175 tested steel security doors with ratings from SR2 to SR4, along with options certified to STS 202, PAS 24 and EN 1627. SecurGuard doors are made to measure and designed to resist forced entry with heavy duty steel leaves, reinforced frames, security hinges, high security locking systems and tamper resistant hardware.
Within the SecurGuard family:
- SR2 rated doors provide a strong, insurance friendly solution for medium risk sites.
- SR3 rated doors deliver higher resistance for more exposed entrances and high value contents.
- SR4 rated doors are designed for very high security and critical applications.
The SecurGuard+ range adds further high security and blast resistant performance. Different models in the SecurGuard+ line are tested to STS 202 BR2, BR3 and EN 1627 Level 4, making them suitable for premises with low to medium, medium and higher risk of targeted attack. These doors can provide both intruder resistance and resistance to explosive loads where required.
Robust Tuff-Dor and Secur-Dor doorsets
Robust UK produce several well known ranges of security rated steel doors, which Samson Doors can supply as made to measure doorsets.
- Tuff-Dor doorsets are typically LPS1175 tested and security rated to SR2, SR3 or SR4 depending on model. They offer heavy duty construction for external use, with robust frames, reinforced leaves and a wide range of hardware options. Tuff-Dor 2 and Tuff-Dor 2.1 are good examples of external SR2 rated doorsets used on plant rooms, service yards and high risk commercial sites.
- Secur-Dor doorsets are tested to STS 202 and PAS 24, with suitable configurations also achieving Secured by Design status. These are often used in residential and social housing schemes or mixed use projects where PAS 24, SBD and high levels of burglary resistance are required, but an LPS1175 rating is not mandatory.
Metador Defender Xtreme and PASguard doorsets
From Metador, Samson Doors can offer two key security rated ranges:
- Defender Xtreme: a high security steel doorset range that is LPS1175 tested to B3, C5 and D10 (equating broadly to SR2, SR3 and SR4). These doors are designed for demanding commercial and industrial applications and can be specified as personnel doors, fire exits or combination doors where high security and safe escape are both required.
- Defender PASguard: a PAS 24 rated steel doorset, particularly well suited to residential and mixed use projects that need an enhanced security rating, Secured by Design compliance and the robustness of a steel door construction.
Specialist security doors and glazed systems
Samson Doors can also provide security rated doorsets which combine intruder resistance with other performance requirements such as fire resistance, acoustic reduction, ballistic resistance or smoke control. Fully glazed steel security doors and walling systems are available in ranges like Glas-Dor, with PAS 24 and EN 1627 ratings and fire resistance in certain configurations. These are ideal where secure partitioning and high visibility are both important, for example in schools, hospitals, airport terminals and other public buildings.
Choosing the right security rating
The right level of security rating depends on the building type, contents, location and insurer requirements. As a simple guide:
- PAS 24 and lower BR ratings suit residential and lower to medium risk commercial doors.
- LPS1175 SR2 rated or equivalent doors cover many standard commercial, education and light industrial applications where insurers seek a recognised security rated steel doorset.
- SR3 and SR4 rated doors or equivalent BR3/BR4 doors are used where higher levels of high security and extended attack resistance are needed, such as in data centres, utilities, critical national infrastructure and high value storage.
Samson Doors can advise on the most appropriate security rating and product range for each opening, taking into account any insurer conditions, Secured by Design requirements and fire or acoustic performance you may also need.
