  • Front mounted torsion springs on doors over 11ft wide.
  • Low headroom gear (rear mounted springs) available for installations when headroom above the door height is limited.
  • Doors can come with a handle and lock kit and a factory cut lock hole in the 2nd panel up if the door is to be manual. The handle can be located in the centre or offset to the left or right.

Reliable protection and long term performance:

The sandwich panel is the basis for long-lasting and safe operation of your sectional door. Specially designed sandwich panels are used to produce Alutech sectional doors and they have several advantages:

  • The panel thickness of 40 mm provides high resistance to wind and impact.
  • both outer and inner steel sheets of the sandwich panel are interconnected in the top and bottom of the panel. This eliminates separation of the panel due to dramatic lowering of a door, and when in direct sunlight;
  • door panel is made of 0.4 mm steel sheet which ensures great strength characteristics of the door;
  • zinc coating with thickness of 16 microns secures high anti-corrosion properties of the panel;

Alutech 40 mm insulation.

  • Thick insulated panel, twin rubber seals, heavy duty galvanized steel brackets, ball-race bearings in the rollers, robust mechanism.
  • The Frost resistant EPDM seals have two leaves significantly improving air tightness and increasing insulation.
  • They are generous and remain flexible at low temperatures. EN12424 Class 4 wind resistance is able to withstand wind up to 120 km/h.
