R+T Innovation Award 2021

safety meets design


to rolling grilles


Universal ring mesh night closure system for areas with direct customer contact. The ring mesh meets the most rigorous safety standards in building protection concepts. The characteristics of the ring mesh also enables the guiding „around the corner“, in one piece and without seams or holders.


We are proud to announce, that we’ve won the R+T Innovation Award 2021 silver for doors/gates.

The innovativeness of the alphamesh safety system was also emphasised by Dr Claus Schwenzer, Chair of the BVT Verband Tore and Managing Director of Effertz Tore GmbH during the award ceremony: “This is an innovative safety night closure made of a stainless steel ring mesh. That truly won us over”. And when asked what exactly he thought the innovation was, his answer was: “If I am completely honest – regardless of the ring mesh – such a product does not exist in any other material. This is completely new with all the design possibilities. If it were simply hanging straight, which is possible, you could, of course, use a roller grille or roller shutter. But there are many new possibilities here, and I don’t know of any other product – at least now – that can do that”.

Particularly because of the wide range of possible applications and the flexible, architectural design possibilities of the alphamesh safety system, there was great interest and enthusiasm among the trade public. This was ultimately crowned by the presentation of two awards: the Silver Award in the “Doors” category and the Special Gold Award in the “Design” category.

From 21 to 25 February 2021, the R+T World’s Leading Trade Fair for Roller Shutters, Doors and Sun Protection was held digitally for the first time because of Corona. With 22,000 visitors from 110 countries, it was also a complete success virtually. proMesh GmbH also presented itself for the first time at R+T with alphamesh safety systems.



The bottom end profile (U-ground profile), the ring mesh and the top end profile (U-ceiling profile) generate the visible unit of „night closure with alphamesh ring mesh“.
The top end profile with the upper support structure is permanently connected to the ceiling (screened or directly integrated in a suspended ceiling). The top end profile is used to attach and hold the alphamesh ring mesh. If the night closure is completely closed, the top end profile works as a height-regulating element for the closing counterpart: the bottom end profile. The bottom end profile is used as the lower collecting tray of the ring mesh, and is directly connected to the drive shaft by using steel cables and deflection pulleys. With the support of steel cables, pulleys and the drive shaft the bottom end profile will be directly lifted and lowered.

The night closure is locked either with electromagnets that are recessed directly and completely in the floor under the ground tray, or with side-mounted locking bolts which are installed at the lower end of the lateral guide profiles.

The drive motor (shaft-mounted motor 3 x 400 V) is directly connected to the drive shaft on top. The dimensions and the power of the motor unit depend on the size of the alphamesh safety system. The motor unit can be programmed via a controller, so that the ring mesh night closure can be individually lifted and lowered. The operation is executed via pushbutton switch, key switch, badge reader or radio remote control with hand-held transmitter. Necessary safety components such as a contact strip (safety edge), light barrier (photocells), etc. can be offered on demand.


  • Protective device from a single and seamless piece of ring mesh.
  • It can be realized in virtually any form.
  • It can be implemented as a „standalone“ solution, as a ceiling solution, floor solution, or between room elements or partition walls.
  • Theoretically implementation is possible in unlimited dimensions.
  • Closure system with invisible high-performance electromagnets.
  • High degree of customisation depending on customer and application requirements.
  • A system without guiding, holder and locking installation or separate components (there are no floor rails, guide rails, corner connections, carrier systems).
  • Well thought-out, reduced mechanical basic concept for a long service life with frequent use cycles.
  • High-quality and individual components for a trouble-free operation.

Technically advanced and architecturally appealing.

The secure day and night closure solution, consisting of a fine metal ring mesh, was specially designed for shopfitting, but also offers a wide range of possible uses in the context of building security concepts, e.g. for shopping centers, shopping arcades, trade fairs, stadiums or airports.
