FAQ
What are the benefits of steel doors compared to timber doors?
Steel doors resist warping, rotting, insect damage, and require less ongoing maintenance than traditional timber alternatives. For more information about the increased safety and security, weather resistance and lifespan of steel doors compared to timber doors, please contact us.
How do I measure the structural opening?
The structural opening refers to the inside dimensions of the opening (or reveal) where the doorset is to be fixed. Be sure to measure top, middle and bottom for the width, and left, middle and right for the beight. The smallest dimensions for each should then be used. Check out our Site Survey Sheet for more information and tips about accurately measuring a structural opening.
How do I describe the opening direction of a door?
We view our doors from the outside looking in when determining orientation.
You can decide if you prefer the hinges on the left or right and whether the door is opening out, towards you or into the building when you order a personnel door.
For fire exit doors, you can decide if you prefer the hinges on the left or right, but the door can only opening outwards.

Warranty & After Care
The Warranty offered will depend on the door type and the environment it will be installed in (C1-5). Please contact us for further information.
We recommend that doors and their associated hardware undergo maintenance checks and thorough cleaning at least every six months, with doors that experience heavy use or that are located in exposed locations being assessed more frequently.
This encompasses all parts and components; for further information please read our Care & Maintenance Instructions, which can be found in the Useful Downloads section.
What is a C3 / C4 / C5 area?
BS EN 12944 classifies environments based on their corrosivity risk, with C1-C3 ranging from very low to medium, C4 is high, and C5 is very high. This applies to both interior and exterior environments, for example a C4 classification can be coastal areas 300m-2000m from the sea, or chemical plants/swimming pools. Therefore our anti-corrosion warranties vary depending upon the application that the door will be installed in, and you must advise us if the installation will be anything other than C1-C3 for our anti-corrosion warranty to apply and to allow us to upgrade your paint finish, hardware and apertures if applicable.
