Reliable protection and long term performance:

The sandwich panel is a basis for long-lasting and safe operation of sectional door. Specially designed sandwich panels are used to produce Alutech sectional doors and they have several advantages:
  • design of panel with thickness of 40 mm provides high resistance to wind and impact loads;
  • both outer and inner steel sheets of the sandwich panel are interconnected in the top and bottom of 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;
Front side of the panel is enameled with polyurethane coating modified by polyamide particles (PUR-PA), that is:
  • highly resistant to scratches and cuts caused by mechanical action;
  • well tolerated to temperature and humidity fluctuations;
  • has high hardness and elasticity;
  • has excellent anticorrosion properties;
  • resistant to detergents and chemicals.

  • No need to worry about standard sizes as all doors are made to measure. Simply send us your garage opening sizes and ideally e-mail us digital photos of the aperture and the inside of your garage so we can check all clearances for the tracks and mechanism and advise accurately for your specific requirements.
