ALU-CO — Letterboxes, Aluminium Profiles and Sheets in Luxembourg for 40 Years
Distinctive, secure letterboxes, parcel boxes, made-to-measure aluminium profiles, sheets and panels: ALU-CO is the Vitralux Bradtke department for aluminium and metal solutions at the entrance, on the façade and inside the building, across Luxembourg.

A name that counts for aluminium in Luxembourg
ALU-CO has been on the Luxembourg market for over forty years. With more than 1,000 installations behind it, the department covers the whole chain: sale, advice given in person, cutting to measure and professional installation of letterboxes, aluminium profiles and sheets.
ALU-CO has a website of its own — www.aluco.lu— where customers can see the whole range, look through the configurations and request a quotation.

Letterboxes and parcel boxes in Luxembourg — design, security and personalisation
The letterbox is the first impression an entrance gives, whether to a house or an apartment block: it has to look right, stand up to hard use and work properly. ALU-CO offers a complete range of individual and communal letterboxes, certified to the European standards, available in a great many finishes and fully configurable to the architecture of the project. To keep up with the explosion in online deliveries, ALU-CO also offers parcel box systems, either on their own or built into a communal bank.
The 6 ways they can be mounted
| Free-standing (on posts) | Letterboxes on posts, ideal for houses. They stand in front of the property with no wall fixing, so you can put them exactly where you want. |
|---|---|
| Surface-mounted (on the wall) | Fixed directly to the façade or the boundary wall. Easy access from outside. The usual answer for houses and small blocks. |
| Recessed (into the wall) | Built into the masonry or the partition for an elegant, discreet architectural finish. Post goes in from outside, comes out from inside. |
| Through-wall (access from both sides) | Accessible from both sides of a wall: ideal for entrance lobbies where post is delivered from outside and collected from inside. |
| Side access | Access from the side of the box. The right answer in tight spaces where there is no room to reach it from the front. |
| On a fence or gate | Mounted on a fence, a gate or an entrance pier. Ideal for properties whose gate is set well back from the road. |
Documents to download
Two references decide the finish of your letterbox: the RAL colour chart for powder coating, and the technical data sheet for anodising.
Anodising data sheet
The complete guide to ELOXAL anodising: the colours available (natural aluminium, GRANODAL® grey, gold, bronze and Sandalor® shades), the six surface preparations E0 to E6 under DIN 17611 (brushed, polished, matt and so on), the ALANOX® finish with its stainless steel look, and the technical data (hardness 250–450 HV, a coating of around 20 µm, corrosion resistance). Everything you need to pick the anodised finish for a letterbox that lasts and looks the part.
Download the anodising data sheet (PDF)RAL colour chart
The full RAL chart available in powder coating, from RAL 1000 to RAL 9000, plus the Fine Texture & Metallic finishes (White Aluminium, Grey Aluminium, DB 703, Antico Grey & Brown and others). Choose the exact colour of your letterbox so that it sits with your façade, your joinery or the colour scheme of your building.

Powder coating and anodising — two ways to bring out the best in aluminium
Powder coating gives you all but unlimited freedom over appearance; anodising (ELOXAL) gives natural, permanent protection while keeping the metallic look of the material.
Powder coating
Coloured powder sprayed on electrostatically and then cured at 200 °C: the polymerised coating is perfectly even, with no runs and no build-up.
- Hundreds of RAL colours available
- Finishes: matt, gloss, satin, textured, metallic
- Excellent resistance to impact, corrosion and UV
- Solvent-free paints — an environmentally sound process
- Cleaning with soapy water only
The RAL colour chart is downloadable at aluco.lu.
ELOXAL anodising
An electrochemical process that turns the surface of the aluminium into a dense oxide layer around 20 μm thick: the layer is part of the metal itself, so it cannot flake or peel away.
- Hardness of 250 to 450 HV — comparable to some steels
- The natural metallic look is preserved
- Natural shades: silver, champagne, bronze, black
- Strong colours available in 5 levels of brightness
- Compliant with the European standards — dimensions unchanged
The anodising data sheet is downloadable at aluco.lu.

Frequently asked questions about ALU-CO
Yes. ALU-CO systems come in a great many finishes and colours. For architect-led projects or buildings with a set colour scheme, RAL finishes can be produced to order through the powder coating process. The aluco.lu site sets out the options and lets you look through the configurations.
ALU-CO handles both supply AND installation. ALU-CO teams work across the whole of Luxembourg to install the systems professionally. It is a turnkey service, from choosing the product to the final handover.
Yes. ALU-CO cuts aluminium profiles and sheets to measure. Just give us the lengths you need when you order. Delivery straight to site is also available on trade orders.
A letterbox takes ordinary post: letters, magazines, small packets. A parcel box is a larger unit designed to take online deliveries: its opening lets a courier drop in a medium-sized parcel, with a security mechanism that stops anyone taking it back out without a key. ALU-CO supplies both, separately or as a combined system.
Powder coating is the answer if you want a specific colour (the RAL shades) or a particular finish (matt, gloss, satin). Anodising keeps the natural metallic look of the aluminium and gives it exceptional hardness and corrosion resistance. ALU-CO offers both processes, depending on your project.
