Thank you for your help.
Quantity : 500bars of 10ft, but may be more.
I am actually interested in a company with a range of existing products (circle, square... sections). We use aluminum right now, but it's too heavy.
I have a project where I need carbon graphite tubes from 10mm to 80mm diameters, as rigid as possible (minimum 3mm tickness).
Where can I find a supplier ? Preferably in the usa, but anywhere else is welcome too.
(Circle sections, but why not other shapes such as square or triangle).
Thanks !
