Surfaces and designs

heroal systems offer you a great freedom of design and a wide variety of options. All coating technologies are well-tuned to each other and provide for a uniform colouring of the different systems.

Surfaces and designs

High-quality surfaces for an individual architecture

heroal systems for windows, doors and curtain walls as well as roller shutters, sun protection and roller doors offer individual design options for a major part of the building shell. Excellent surface coatings by heroal meet the demand of investors, architects and planners for a fine-tuned colouring of the different systems. Since the systems, e.g. windows and roller shutters, can be combined with each other, heroal has developed different coating technologies for the different requirements of each system. The highly weather resistant heroal hwr powder coating for extruded profiles has been ideally adapted to the 2-layer thick coating for roll-formed products like roller shutters and roller door slats. In addition, individual surfaces with wood, rust or concrete looks can be created with heroal Surface Designs (SD).

What’s so special about heroal surfaces?


With industry-leading coating technologies, like heroal hwr powder coating or heroal Surface Designs (SD) for true to detail wood, concrete or rust surface looks, extremely high-quality surfaces for unique projects can be created.

Exclusive colours

There are no limits to your creativity with the wide range of available colours and designs, e.g. more than 500 RAL and DB colours in different gloss rates or the exclusive Les Couleurs® Le Corbusier colours.

Perfect colour uniformity

heroal’s product portfolio covers a major part of the building shell. That means you do not only get everything from one source, you also get ideally matching colours and surfaces – whether for windows, doors, roller shutters or sun protection.

Test exclusive colours for aluminium surfaces

For the coating and refinement of surfaces, heroal partners can choose not only from the entire RAL colour range, but also from the exclusive, unique Les Couleurs® Le Corbusier colours, which can be harmoniously combined with each other. That way, windows, doors, curtain walls, roller shutters, sun protection and roller doors can be perfectly adapted to the look of the building. The heroal coating technologies provide for surfaces offering colour stability, gloss retention and resistance to weather. Thanks to the availability of different gloss rates for surfaces, it is possible to distinguish the subtlest nuances of a colour. The gloss rates can be created in different designs, ranging from dull mat through brilliant to metallic.Test the effects of different colours, nuances and decors in our surface configurator.


Innovative surface coating

For decades, heroal has set international quality standards in the field of aluminium coating – of course, fully complying with all ecological requirements. heroal hwr powder coatings meet the highest demands of Qualicoat‘s class 2 and GSB’s master quality. The weathering test proves: the heroal hwr powder coating is colour-fast even under extreme weather conditions. The industry-leading surface coating provides for the various options for the most different requirements and architectural styles.

  • heroal hwr powder coating

    heroal hwr powder coating

    With the best values in terms of colour stability, gloss retention, weather resistance and UV-protection, heroal hwr powder coatings meet the highest demands of Qualicoat’s class 2 and GSB’s master quality (quality seal for piecework coating) – of course, fully complying with all ecological requirements.

    Coating process:

    1. aluminium base material
    2. chromium-free passivation
    3. heroal hwr powder coating

    heroal has been setting international quality standards in aluminium coating for decades. The new vertical powder coating system, which was commissioned at the end of 2012, is testament to heroal's commitment to future quality standards too. The heroal hwr powder coating meets the exact requirements of Qualicoat class 2 and complies with the master quality of GSB, as well meeting all ecological requirements.

    heroal Surface Design (SD)

    With heroal Surface Design, aluminium windows, doors, curtain walls or patio roofs can be created with wood, concrete or rust looks. After having been heroal hwr powder-coated, the profiles are wrapped in a transfer foil with sublimation ink. Extreme heat creates a vacuum, and the ink cures into the powder coating. Then the foil is removed, revealing the high-quality surface look. The bonding of heroal SD and the hwr powder coating underneath is very strong. That way, heroal Surface Design (SD) provides for surfaces of excellent quality.

    Coating process:

    1. aluminium base material
    2. chromium-free passivation
    3. heroal hwr powder coating
    4. transfer film with sublimation ink

  • heroal 2-layer thick coating

    heroal 2-layer thick coating

    Thanks to coatings using heroal 2-layer thick coat, roll-formed aluminium parts, like slats for roller shutters and roller doors, are especially colour-intensive and colour-fast, as well as abrasion-proof and weather resistant. The thick coat is applied in a rolling process and then stoved at 240 °C. After the application of a clear coat, the elements are finally roll-formed. This is first class quality. Therefore, the classification society Germanischer Lloyd certified the 2-layer thick coating as suitable for being used on ships.

    Coating process:

    1. aluminium – base material
    2. pre-treatment
    3. prime coat
    4. clear coat

  • Eloxal process

    Eloxal process

    During the Eloxal process, the electrolytic oxidation of aluminium, direct current turns electrolytes containing oxygen on the aluminium surface into oxygen. The following reaction of the oxygen and the surface creates a build-up of aluminium oxide. The oxide provides for corrosion protection and also prevents the aluminium from further oxidation, while at the same time preserving the metallic appearance of the surface.

    Coating process:

    1. aluminium base material
    2. barrier coat
    3. porous Eloxal
    4. metal oxides
    5. sealing
