Sizes to Suit

Acoustic Rating for reduced noise

Our acoustic double steel door has an acoustic rating of 35dB which makes it excellent for use in applications such as recording studios and industrial environments where reduced sound transference is essential.

Long lasting strength

All of our steel doors are made from galvanised steel, built to withstand the test of time and you can be assured they will last when exposed to the elements.

Security Upgrades Available

For applications which require an increased security level, there are a range of security upgrades available including 3* cylinder upgrades, and stainless steel handles.

DDA Compliant Doors

As with all of our steel personnel doors, this door is fully compliant with the Disability Discrimination Act.


The dB rating is the maximum decibel rating achieved in lab conditions, as shown in the graph in the test report available in the downloads section. Real-world conditions may vary.

How do I choose the hinge side and opening? (Handing)

Hinge side and opening is always determined viewed from outside. The active leaf (the door which opens first) can be determined as follows:

Example 1: LH active leaf opening out. The handle is on the left door and you would pull the door towards you.
Example 2: RH active leaf opening in: handle is on the door to the right-hand side and you push the door away from you.

See our handy illustration here

How do double doors get delivered?

Your steel double door will be delivered in a minimum of 4 boxes:

2 x door leaves packaged individually
1 x box containing the hinge posts
1 x box containing the head of the frame and the bottom threshold

By delivering your steel double door frame in self-assembly pieces, it reduces the amount of handling of the doors. This in turn reduces associated health and safety risks as the door and frame are delivered in separate, manageable boxes meaning they’re less likely to be dropped causing unnecessary damage to the door.

Please note, delivery is kerbside only. We request that another party is present to help unload.

*size dependant

What are the door sizes? What is the clear opening?

The sizes listed are external frame sizes.
We offer side panels and over panels if you need to add to the width or height of the door. We also offer a cut down service to reduce the height of the door
To calculate the clear opening (when the door is open), subtract 110mm from the width dimension. E.G. 895mm-110mm=760mm clear opening
See the video on how to measure here

What is Security Trim?

The security trim kit fits around the perimeter of the door frame, preventing any packing from being seen externally and making the door as a whole more secure.
It hides un-level or large gaps, hides the position of fixings eliminating the risk of tampering from intruders and crucially protects the fixings from attack.
