Garage doors

The sectional garage door leaf is characterised by excellent heat-insulating and sound-absorbing properties combined with a modern design of microprofiled panels. It is the most robust garage door in the market.

A major advantage is that the range of garage doors and industrial doors fit together very well when it comes to, for example, rail systems and hinges. With regard to other materials and material thicknesses, no expense has been spared either. This offers more opportunities in projects where both garage doors and industrial sectional doors are used.

  • Panels for every architectural style
  • Extensive colour palette
  • Same spare parts as our industrial doors

Our sectional garage doors

The required free space in the garage depends on the clear height of the door opening and the operating variant (manual or automatic operation). We therefore distinguish the following door types: GD210, GD130 en GD70.


GD 70 – Low-headroom system with rear mounted torsion spring/s – this system is only available with operator.


GD 130 – Low-headroom system with rear mounted torsion spring/s.


GD 210 – Normal track system with torsion spring/s above the door leaf.

There is an extensive choice of vision panels, window elements and RAL colours. Alpha sectional garage doors fully comply with the EN13241 standard and come into their own in modern designs for residential construction.
