Security Doors.

Quality Guaranteed.

Kirncroft Security Doors have a strict focus on build quality with high-performance hardware fitted as standard. As a result, it is impossible to find better value for money steel doors.

We make our steel security doors in our own factory.

Every door is made in our own purpose-built 10,000m2 manufacturing facility with a 50-point quality control inspection before it ever reaches our customers. So while other companies struggle with processes outside of their control, we guarantee high-quality products by manufacturing in-house.

Our security doors are made from heavy-gauge galvanised steel to prevent rusting and increase their resistance to attack. Low quality, light-gauge steel results in doors lacking strength, resistance to attack, and overall durability.

Security

Security tested to PAS24
High security as standard
Anti-drill and anti-snap locking system
Extra secure 10-point locking system designed specifically for our security doors. Tested and performing in the real world since 1999

Other door suppliers often adopt a cheap approach when specifying a locking system. In doing so, they don’t make security and durability a top priority. In continuous development for over 20 years, our 10-point locking system meets the requirements of the real world. Kirncroft security doors are designed and tested to PAS24, reinforcing a high level of security and overall performance.

Durability

Steel Security Doors tested to
BS EN 1191 for
50,000 cycles

With a Kirncroft door, you can open, close, lock, and unlock two cycles per day for over 68 years and have the assurance of a door that works properly and efficiently.

Kirncroft Security Doors 10-Point Locking Features

Internal construction

Galvanised steel subframe with 4mm
(3/16″)
round-bar steel mesh
Heavy duty fixing plates for locks, hinges and surface mounted hardware
Injected polyurethane insulation

The internal construction of our steel security doors is such that the components reinforce the door’s strength. For example, using extra-strong reinforcing plates ensures that the screws securing the locks and hinges cannot become loose. In addition, by constructing our security doors with hard-setting injected polyurethane foam, they have integrity beyond just the external steel skin, and the internal structure guarantees strength and durability that will last for years.

Insulation

Door AND frame injected with polyuerethane insulation.
Part L compliant –
U value 1.8W/m2K

Other door suppliers often overlook insulation, and they use cheap material to insulate their doors. For example, when used in a steel security door, mineral wool and honeycomb paper insulation often do not meet the requirements for U-values. However, an accredited laboratory has confirmed the U-value of the Kirncroft security door, using the correct method of calculating the door and frame as a complete unit. By using polyurethane insulation, our security doors are both structurally reinforced and meet thermal performance requirements.

Rustproof

Polyurethane insulation seals internal components
Stainless steel threshold
Stainless steel locking rod tubes
304 grade stainless steel hardware

If steel security doors are not properly insulated, they can be prone to rusting from the inside out. Insulation made of mineral wool or honeycomb paper naturally collects moisture. The moisture spreads inside the door and increases the chance of rust. Kirncroft security doors are made from galvanised steel inside and out with polyurethane insulation that seals internal components and stops them from coming into contact with any moisture.

Waterproofing

Fully sealed door, frame and threshold.
Advanced door and frame sealing system.

Having a fully sealed door, frame, and threshold prevents water from entering the internal components of the door and prevents them from rusting from the inside out. With our advanced sealing system, the frames and thresholds stand firm against water ingress. Waterproofing guarantees that your security door continues to provide security even when the weather takes a turn.

Handles

Grade 304 stainless steel handles as standard
DDA & Part M compliant
Compliant with disability regulations
Tested to
BS EN 1906 for
200,000 cycles

Handles are just as important an aspect of a steel door as the internal components. Other suppliers focus on budget security doors that incorporate low-quality hardware, turning a blind eye to longevity. In contrast, we include Grade 304 stainless steel handles as standard for our doors. In addition, each handle is compliant with regulations and is tested thoroughly before dispatch.

Hinges

304 grade stainless steel fully welded anti-knockout hinges as standard
Tested to BS EN1935 grade 3

Kirncroft steel security doors use hinges with a complete stainless steel welded design, ensuring they can endure the elements and withstand physical attacks.
