Door Construction

LEAF AND FRAME SHEATHING

The main construction material for the leaf and frame of our doors is double-sided hot-dip galvanised sheet metal, coated with veneers resistant to UV radiation and atmospheric conditions. The use of hot-dip galvanising provides a thicker layer of galvanising and significantly better corrosion protection than in the case of galvanising.

Before the coating process, the sheet undergoes a multi-stage preparation process including degreasing, chemical phosphating, rinsing and passivation.

Before the veneer is applied, the surface of the veneer is subjected to a chemical activation process that provides exceptional bonding strength.  This process is a closely guarded technology that has been developed as a result of the manufacturer's many years of experience. The sheet is coated by hot-rolling with special veneers that are resistant to UV radiation, precipitation and temperature changes.

The veneers used are thicker than those used for window joinery, which means that the sheet can be successfully profiled and pressed after the coating process. After treatment, the material retains the required mechanical and aesthetic properties, providing exceptional tensile strength, which is crucial for use in door joinery.

At the end of the process, the sheet is subjected to a visual inspection by employees and to an automatic inspection in a special quality supervision system, which verifies that the production has been carried out correctly. From each batch, samples are taken for quality testing and stored by the manufacturer for a period of 5 years.

Such a comprehensive, accurate and rigorous production process for the sheets used makes them a reliable material with excellent mechanical properties and outstanding aesthetic qualities. All structural components are manufactured on a modern automated production line equipped with precise numerically controlled machines.

The production process ensures full repeatability and matching of the sub-assemblies used, which in the final product form a compact, robust and tight construction.

GLAZING AND GLAZING FRAMES

In all our models, we install 3-glazed, 2-chamber composite glass with the use of "Venetian mirror" glass as standard.

In the INOX collection models we use high-grade brushed stainless steel. The frames in the BLACK collection are made of powder-coated aluminium sheet. Both solutions adopted ensure high mechanical strength and resistance to weather conditions.

ALUMINIUM FRAME

CONSTRUCTION OF THE ALUMINIUM FRAME

The door frames are manufactured from aluminium profiles with a thermal break. The core structure is made of high-grade aluminium alloy, ensuring rigidity, corrosion resistance, and dimensional stability. The polyamide thermal barrier effectively reduces heat transfer, improving the overall thermal insulation of the door assembly.

The frame and threshold are designed with a continuous gasket channel, allowing for stable and uniform seating of the seal. This solution guarantees full perimeter tightness between the door leaf and the frame. The combination of high-quality materials, optimised profile geometry, and structural stiffness greatly facilitates installation and ensures long-term durability.

SURFACE FINISH

The frame is finished with a UV-resistant decorative foil, providing protection against weather conditions and discolouration.
In the LOFT version, the surface is powder-coated in black (matt finish), offering high resistance to mechanical damage and a modern appearance characteristic of the industrial style.

MANUFACTURING TECHNOLOGY

The thermally broken aluminium profiles combine high structural stability with low heat transfer coefficients. Both the UV-protected foil and powder coating provide durable surface protection, ensuring resistance to sunlight, temperature variations, and moisture. The finishing technology guarantees excellent long-term aesthetic and mechanical performance.

EQUIPMENT AND FUNCTIONAL FEATURES

The aluminium frame is integrated with an aluminium threshold featuring a thermal break.
The standard equipment includes:

• Three 3D adjustable hinges, allowing precise alignment of the door leaf in all three planes;

• A continuous perimeter gasket, ensuring airtightness and acoustic insulation;

• Pre-drilled holes for anti-burglary bolts, improving break-in resistance;

• Locking strike plate.

DOOR LEAF

DOOR LEAF CONSTRUCTION

The basis of the leaf structure is a high-quality, double-sided hot-dip galvanised sheet metal with a core thickness of 0.6 mm, hot-coated with a special weather-resistant veneer with UV filter.
 The material is formed using state-of-the-art punching and bending machines.

TECHNOLOGY USED IN THE CONSTRUCTION OF THE DOOR LEAF

The sheet metal core is hot-coated with a special veneer that is resistant to UV radiation, weather conditions and temperature fluctuations. The durability of the raw material used is ensured by an advanced sheet metal surface preparation process including degreasing, chemical phosphating, rinsing, surface passivation. During the coating process, the surface of the veneer is additionally chemically activated, which enhances the bonding strength. The use of thick veneers guarantees exceptional tensile strength, which is essential for use in door joinery. As a result, we obtain a material with excellent mechanical properties and outstanding aesthetic qualities.

DOOR LEAF EQUIPMENT

As standard, our doors are equipped with a gasket, 2 three-bolt locks and 3 anti-theft bolts.

The Premium collection is filled with foamed polystyrene.
