TRIANTLUX specialises in designing and manufacturing decorative hidden leaves and panels for entrance doors. By combining contemporary design, precise craftsmanship and premium materials, we create solutions where every detail contributes to a building's distinctive look.
As a member of the TRIANT group, we let customers pair their aluminium or PVC joinery with a fully personalised entrance door, made to their wishes and the building's architectural concept.
Alongside products for TRIANT system customers, TRIANTLUX also offers contract manufacturing of hidden leaves and decorative panels for other joinery manufacturers. Whatever manufacturer produces the joinery, TRIANTLUX models and panels can be custom-made and integrated into different systems according to the project's technical requirements.
Full personalisation is where the real value lies. Beyond the standard models in our collection, customers can create their own design for a hidden leaf or panel. Working together with our team, we develop and build completely unique solutions, tailored to individual wishes and the building's architecture.
TRIANTLUX brings together functionality, precise manufacturing and modern design so that every entrance door becomes a defining feature of the building.
Choose the material, colour and style, and watch the door change in real time before you make your final choice.
