Square plastic tubing?

[linusab]

Hello,
I am searching for square tubes or rectangular profiles made of plastic, PVC tubes but square. Dimensions roughly 20-70mm.

I have searched the internet and hardware stores without luck. Does anyone have any tips?

Thanks for the help. The ventilation ducts are probably unfortunately a bit too wide.

Do you know if plastex has any wholesaler in the Stockholm area?

At Bauhaus, they have a variety of profiles in metal and plastic. However, no square ones in plastic, only square profiles in Alu and steel.
