Aluminum 6061 is an alloy that is lightweight, sturdy, and highly resistant to corrosion. On top of that, we added T6 heat treatment to enhance the strength of the aluminium, making it not only feather-light and sturdy but also allowing it to be given a beautiful finish.

Production processes of all parts are done through the highest-quality CNC milling process, one part at a time.
