Full-Service in aluminium profiles

We'll take care of it!

Aluminium profiles

You can have all your aluminium profiles extruded at ALUDEX!

Since we have many different extrusion presses that we can chose from (900 MN upto 6500 MN), we can select the perfect match for your profiles and therefore offer you the best conditions!

EN AW 6060, 6061, 6063, 6005, 6082
Profile weight
0,05 kg/m until 70 kg/m
Profile dimensions
Min. circumscribed diameter 20 mm
Max. circumscribed diameter 620 mm (!)
Please find below our press diagram:
Surface treatments
Mill finish
Anodised (Qualanod, L_max = 14.000 mm)
Powder coated (Qualicoat, L_max =  14.000 mm)
Special: brushed, sandblasted, polished, stainless-steel look, etc.

We'd be glad to support and advise you concerning:

  • Your profile design, feasibility
  • Surface treatments (specifications, what to use when etc.)
  • CNC machining possibilities (e.g. cutting, milling, drilling etc.)
  • Hedge contracts, fixing your purchase prices over a longer period
  • Assembly of your aluminium profile products



When extruding an aluminium profile, a section of an aluminium billet is pressed with great force through a steel die. The openings made in this die, define the shape of the profile which is produced. The complexity and feasibility of a profile depends mainly on:

  • the dimension of the profile (the circumscribed diameter)
  • the number of chambers in the profile,
  • the aluminium alloy (e.g. EN AW 6063 T6) and
  • the required surface quality (decorative, industrial).

Below you can watch a short movie to get a general impression of the extrusion process.

When the profiles come out of the extrusion press, they undergo various treatments such as cooling, stretching, sawing, stress relieving heat treatment and wrapping. A surface treatment often follows, as the final application of an aluminium profile often also serves an optical purpose. This happens mostly by anodising or powder coating the profile. 


When anodising, an aluminium oxide skin is applied in an electrolytic way which ensures a natural hard and wear-resistant surface. Moreover, it gives the aluminium a nice, uniform and matt colour. At ALUDEX there are many different colours and quality evels of surface finish possible, including highly decorative!

Powder coating

Various lacquering techniques are available for the lacquering process, powder coating being the most common one. During this process, electrically charged particles of epoxy- or polyester powder are applied to the aluminium. Then, the whole is put into an oven where the powder melts and so ensures a smooth and wear-resistant skin on the aluminium. Nearly all desired colours and metallics are available.

On this page, the extrusion process, the anodising and powder coating of aluminium profiles have only been explained briefly. Please contact our employees, should you be interested in more detailed technical information.


Having your new profile produced

Before you can go ahead and have your aluminium profile extruded, you need to be sure that the profile design actually fulfills its required function. If you need to conclude afterwards that the profile doesn’t comply with its defined functionality, then unnecessary costs have been made (e.g. die costs) and lots of time is lost. Therefore it is important that this goes right from the beginning. We can certainly assist you in this process with our year-long experience in this area. Here you can find the procedure, we would guide you through:

The procedure:
1)   You send us your drawing or your inquiry (which is also possible via this page)
2)   We'll send you our offer, eventually with remarks or suggestions on the profile design
3)   If you agree to our offer, we'll send you the final profile drawing (with profile weight, perimeter etc.)
4)   You need to approve this profile drawing by sending it back to us (signed with name & date)
5)   Based upon this approved drawing, we'll produce the die
6)   When the die is ready (2-4 weeks), we'll perform a die trial
7)   You'll receive a profile sample which also needs to be approved (it's a dimensional check only)
8)   If the profile sample is approved by you, we'll harden the die ...and we're ready for serial production!
