Metal+ concept

The construction basis of each Heinen door

Composition of the Metal+ door

Profile of a Heinen door
1 Concrete or sealing mortar.
2 Frame (steel sheet 15/10 or 20/10) covering the thickness of the reveal for a good-looking finish (with optional thermal break).
3 Double lip seal.
4 Insulation around the edges of the door (with intumescent material for fire doors).

Tubular steel structure (60 x 60 x 2 mm).

6 Door skin comprising 15/10 galvanised steel sheet screwed into the tubular structure and individually replaceable.
7 Self-lubricating hinges, adjustable and replaceable, screwed into the tubular door structure.
8 Hyper-strong synthetic material (for optimum protection of the insulation or intumescent material incorporated into the door leaf).

Minimal total cost. Heinen is the least expensive solution in the long term

  1. Its unique Metal+ construction ensures its long service life.
  2. Maintenance is minimal, even in extreme conditions.
  3. Repairs needed due to damage or vandalism are easy and limited as the elements are screwed on to the tubular structure (hinges and cover plates).
  4. Heinen doors have a 15-year warranty!

Reliable robustness. Heinen owes its robustness to its “Metal+” door concept,
the construction basis of each Heinen door.

  • The Metal+ concept stands out thanks to its modular design: each door has the same robust structure so that the basic performance features can be combined with a wide range of high-level performance features in a single door, whether it is fitted indoors or out!
  • Another reason for this endurance is the use of screw-on hinges. This makes it possible to adjust the door in three dimensions after it has been fitted, guaranteeing that it is perfectly adapted to its location; ensuring maximum ease of use; and avoiding the malfunctions ordinarily caused by the heavy-duty use of the door. As the exterior plates are also screwed on, there is no need to change the entire door set: only the damaged part is replaced.
  • Thanks to the unique Metal+ concept, Heinen doors are constructed on the same basis and always have the same attractive look, regardless of their performance features.
  • All Heinen doors are made to measure, up to 6m!

The great advantage of Heinen doors is that the performance features can be combined on a bespoke basis.

Frequent door problems

Installing Metal+ doors

The extreme robustness of Metal+ doors is due to the fact that they are fitted in cast concrete.

The door frame is first attached mechanically using metal brackets (fitting clamps) before being completely filled with concrete, thereby providing maximum protection against heavy-duty use, vandalism, fire and noise.
