Metal+ Inside Technology



All hung doors from Heinen are constructed on the same basis and have the same type of profile.
This basic door is called the Metal+ door and already comes with certain performance features.


This is what we call Metal+ Inside technology.

Basic performance features



Frequency of use: f8 (1,000,000 cycles)

Mechanical resistance: M+7

Acoustics: Rw 30 dB

Thermal insulation: T4



Optional performance features


On top of the basic performance features offered by the Metal+ door, you can add several features which can all be combined!

This means that you can have, for instance, a door which provides fire resistance, burglary resistance and acoustic insulation.




All Heinen Metal+ doors are purpose-made with the aim of reducing the total costs you pay for having a door fitted. Our product line manufactures items ranging from small trapdoors to large hung doors. A single door leaf can be up to 5.5 m high and 2.4 m wide.


The fixed window frames (for glass walls) are also purpose-made. The maximum dimensions of a frame are also partly determined by the security performance required (fire, vandalism, noise etc.). Window frames and doors can be fitted next to each other without any problem.


Given that prices vary incrementally, customers are free to play around with the dimensions until they reach the optimum result in terms of cost and appearance.


For instance, non-glazed Heinen hung doors have a fixed price for openings in walls up to 1070 mm wide and 2228 mm high, for a wall which can be up to 200 mm thick.

Specification clauses


We have developed specification clauses covering both the basic performance features of the Metal+ door and the additional performance features, depending on your application requirements. These specification clauses are based on the following three pillars:


  • Guaranteeing the door’s long-term use
  • Providing genuine, effective security over time
  • Guaranteeing a financial return and the lowest cost of usage over a minimum of 15 years

Customer case study (Cargill) :


Frederik Baes, Maintenance and Projects Manager at Cargill N.V. Izegem, Belgium.



“Cargill is one of the largest family-run businesses in the world with more than 1,000 plants in numerous countries, employing around 160,000 staff. It has its headquarters in Minneapolis, USA. We produce agricultural products for the food and feed industry. Cargill N.V. in Izegem specialises in the bulk production of vegetable oils and fats.


The plant’s doors are subject to heavy use every day and are exposed to every kind of weather. Certain zones in the plant are food-safe areas where strict regulations apply. In these areas the use of unpainted, corrosion-resistant doors is recommended.


Heinen products are well-known for their high-quality finish, simple fitting and low maintenance costs.
The doors can also be easily used during the renovation of existing buildings.
The adjustable hinges do not require any maintenance, even if they are used in harsh conditions.
Heinen offers a solution for different applications, from painted to galvanised doors, from ordinary locks to anti-panic locks, and from ordinary doors to fire-resisting and/or soundproof doors.


Good cooperation between a local contractor and Heinen means that the process of replacing and fitting a door runs smoothly with reasonable delivery times.”

Purpose-made doors help you save money when it comes to the finish, as the doorframe is tailored to the opening. It 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.


This system enables several door and frame items to be assembled in a single unit.

>>> Fitting instructions for hung doors <<<





Thanks to Metal + Inside technology, Heinen hung doors require minimal maintenance and can be easily repaired without having to go ahead and replace completely the whole door set or leaf, which is a time-consuming task.



In fact, the cover plates are not welded, but assembled by screwing them to the internal frame, enabling you to replace only the plate(s) that have been damaged.


The cover plates have an original galvanised finish without any welding. This means that the internal doors cannot be painted, giving an attractive natural steel look.


In the case of fire-resisting doors, the intumescent product is incorporated invisibly into the door leaf. This ensures maximum protection for this fragile product against humidity and mechanical damage, and it is completely maintenance-free!


The adjustable hinges are self-lubricating (bronze bushings) and can be easily replaced just like the rest of the fittings (handles, pull handles, door closers, anti-panic bar etc.)
