GALVANISED STEEL
The security shutters are constructed in steel elements whose section is
designed to maximise resistance.
The profile of the lower section of each element acts as a drain,
impeding stagnation of water and condensation. Aeration of the premises
may be guaranteed by the insertion of a section of rectangular cell or
honeycomb shutter or simply by inserting a suitable number of holed
elements.
Winding onto shaft in steel tube complete with spring cases mounted on
tempered steel rol-ler bearings and springs of high quality. Galvanised
lateral guides 40- 50-80-100 mm. Lateral registration strips in
reinforced sheet. Security lock with double lateral extension.
The shutters may be moved manually, or by reducer winch or with a motor
reducer group and button control, key selector, remote control, etc.
Various security systems such as light cells, sensor bars, etc., may be
applied.
