Rolling grilles technical information

The width of the material is determined by the width of the folding grille – the wider the grille, the wider the flat material. In the following table you will find information regarding the possible designs for our folding grilles in honeycomb made of flat material. You will also find the appropriate guide rails for each profile.

Diameter of rolled-up folding grille depends on the shaft and material width.

Guide rails
Robust U-profiles in steel, aluminium or stainless steel; at least 1% of gate width according to DIN 18358. Available with or without plastic guides. Fastening of guide rails using angle brackets or underlining as rectangular tube or bracket.
Shaft / axle tube
The winding shaft is statically dimensioned according to the width of the gate; Max. deflection L/500. Galvanised octagonal shafts or primed round steel tubes are used (in accordance with DIN EN 10219).
Brackets
Bearing of the winding shaft is carried out using standard or angle brackets in galvanised steel or primed, statically dimensioned according to the weight of the system. Special brackets for ceiling and recess installation as required.
Box
We manufacture boxes: – as contact protection for automatic gate systems with clear height < 2500 mm – as weather protection for external rollers incl. drive sheathing We deliver systems with tubular motors if required in the readymade external building element. The boxes and guide rails are also colour-coated using standard colours.
