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.
