Aluminium extrusion i need big c-beam

[dazza]

Hi all
Usually I would go to kjn ,for one their local but it seems their range is a bit lacking when it comes to large profile, i've been trawling the web looking for large c-beam extrusion but everything I am coming across is 4080
Does anyone know of a uk supplier with a decent range of c-beam id like something around 160mmx80mm or thereabouts, 4080 is way too small for my job
Anywhere on line UK i should be looking at? thanks

I did have a list of with some UK suppliers from when I was looking at building a router, but I can't find it.
Only thing I can find, is the model I started on used a Kanya 50x100 extrusion - https://www.kanya.com/en/products/extrusion-connecting-system/33-04042019-052147/ma1-2-02-02-200.html

Thanks mc
It does need to be c-beam really, if i have no choice then i,ll have to have a rethink but i'm sure i saw big stuff somewhere, a while back, now all i can find 4080 in light/heavy or anodised,Thanks for the reply.

after trying loads of different remedies to the c beam twist on my cnc i ended up opting for the below from valder for my x axis.

it lead to a massive change in end plates, ball screws etc but ws well worth it.

Thanks pal
That looks ideal for what I need I will have a close look at that.
I just need to fit two rails and a rack and pinion to it.:beer:
