Mechanical stress resistance

Doors built to last: defying external stressors

Doors are subject to various degrees of stress depending on where they are deployed – from interiors to doctor’s offices, and from residential entrances to schools. They may have to withstand, for instance, static torsion, impacts from objects, vibrations and heavy vertical loads. Door elements are therefore classified in defined mechanical stress resistance groups: N (normal), M (medium), S (strong) and E (extreme).

neuform doors comply with all German and many international quality standards and test criteria for mechanical stress resistance. But for us, that is not enough. As door specialists, we know that these tests only evaluate certain aspects of wear and tear. And that is why we go a step further, with high-quality components and innovative ideas, such as our PU-protect products. We use high-density fibreboard to reinforce door leaves. And we deploy stabilisers to lend locks, handles and hinges greater strength – and minimise the risk of hardware coming loose, particularly with standard rebated doors. These extra measures allow our products to stay in great condition, even after prolonged, intensive use.

RAL - GZ 426/1- Mechanical stress resistance
The doors are subjected to mechanical stress through external, mainly repetitive sources (hard and soft impacts, vibrations, fatigue, etc.). Classes are defined according to the degree of stress.
Additional quality assurance through an independent organisation. 

DIN EN 1192 - Classification of strength requirements
Doors are used in a broad range of environments. Consequently, performance classes are defined according to mechanical stress resistance.  
​​​​​​​
Comparison of values for door leaves, in accordance with RAL-GZ 426/1 and DIN EN 1192 lt. Table: 

RAL-GZ 426/1 DIN EN 1192 Application, e.g.
N = Normal 1 = Occasional and careful use Home interiors
M = Medium 2 = Medium and careful use Offices and consultation rooms
S = Severe 3 = High and non-careful use Home entrances, kindergartens, hospitals, hotels
E = Extreme 4 = Very high and non-careful use Hostels, schools, barracks
