Hi,

I am going to create a sketch and save it as a weldment profile.

The section is a 600 600 x 40 square hollow section. (Jumbo Section).

The profile is no bother, what I am trying to find out is what are the inside and outside corner radius for this size section.

We have a section table which only goes up to 400 x 400 x 16 which shows inside radius of 32mm and outside radius 48mm (which is 2 & 3 times thickness).

So I could make this section radius 80mm & 120mm, however I cannot find any info to say this is correct.

The smaller the section required then this 2 & 3 times formula changes so for example a 220 x 220 x 6 will ask for 12mm outside 6mm inside (1 & 2 times thickness).

So does any one have a metric chart / or know showing Jumbo section internal / external radius.

Thanks
