Architectural Hinges
ARRONE architectural hinges are often found in schools, hospitals and commercial buildings with consistent and considerable traffic. In these buildings, safety and functionality are imperative. With ARRONE architectural hinges, there is no need to compromise on aesthetics or performance – you can get the product you need, the way you want it.
Reliability and performance.
When specifying architectural hinges, you must feel confident of their reliability and performance.
ARRONE architectural hinges are capable of withstanding high traffic like the footfall experienced in schools and hospitals, as well as heavy duty applications including fire doors.
Tested to grade 13 of the European standard EN 1935, the ARRONE hinge range includes:
- Lift off hinges
- Ball bearing hinges
- PBW hinges
- Concealed bearing hinges
Hinges from ARRONE are also UKCA and CE marked – as well as being third party certificated by CERTIFIRE – and are therefore suitable for use on 30 and 60 minute timber fire doors. They are available with intumescent kits to meet the conditions of the hinges’ fire test evidence.
Technical considerations
Normally, three hinges are fitted to each door. Their positions are determined by the weight of door and its resistance to warping or whipping.

Hinges for use with doors of excess widths
Wider doors obviously increase the pressure and bending moment exerted on the hinge. This must be allowed for by reduction in the maximum mass of the door leaf supported by each grade of hinge.
The factors by which the door mass has to be adjusted for excessive widths of door are calculated by dividing the door height by its width. For a factor of 2 or greater, no allowance has to be made. When the factor is less than 2, the door mass has to be increased by the value required to bring the factor to 2 expressed as a percentage. These percentages are shown in the side loading calculations table.
