What is extrusion?
Extrusion is a manufacturing technique that can be found in various fields (plastics, metallurgy, the food industry, etc.), so this process is not unique to the building industry! It involves compressing the material (in this case, aluminium) and forcing it through a die with the desired cross-section.
At Flandria, we use the extrusion process for our profiles, which enables us to manufacture all kinds of aluminium profiles, whether made-to-measure, standard or on request!
So how do we get our profiles? The aluminium is placed in a cylindrical machine, then pressed through an extrusion die to obtain the desired shape. Extrusion is mainly carried out hot, at 500 degrees Celsius, which allows the metal to be pressed easily, making it malleable. Then, after the cooling phase, the profiles can be cut to the required length!
Extrusion is a rather complex process that requires skill and a good knowledge of metals and machines.
Colours / Powder coating and anodising
Flandria Systems aluminium profiles are available in hundreds of top-quality colours! The choice is yours when it comes to the exact colour of your Flandria Systems extension. Give free rein to your most unique desires…
At Flandria Systems, we use two different techniques to treat the colours of aluminium profiles: lacquering and anodising. Both techniques comply with the strictest quality principles, and thanks to these two techniques, you will be able to enjoy the colour you have chosen for your profiles for much longer!
Lacquering involves applying a powder paint to the surface of the aluminium profile, which is then coated with a layer of thermosetting polyester powder. This gives us a high-quality, long-lasting finish!
Gloss or matt?
You can choose between a matt or gloss colour. This process can of course be applied to all the colours offered by Flandria Systems in gloss or matt.
Anodising is a surface treatment that protects or decorates aluminium parts. It makes materials more resistant to wear, heat and corrosion.
This technique involves cleaning the profiles, then immersing them in a chemical bath, before immersing them in another bath, this time with metal oxide, to be dyed. The last stage involves passing them through a final bath: the steam bath.
