Hi

I'm in the process of replacing my sierras sills with shs 90x90

I was planning on using 2-3mm thickness

Today I contacted just about all the steel suppliers in Adelaide seems 3.5mm is the thinnest I can get.

After a lot of research I have found people use different sizes, some use 100x100x3

If I do go the way of the 3.5mm will the weight (about 10kg per sill) be too much for the thin panels it's going to be welded too and will this cause issues?





Thanks for the help in advance

Cheers
Simon

I used 100x50x4 im pretty sure. It was fine

100x50x4 weighs a lot less than 100x100x3 or 90x90x3.5

100x100x3 = 8.96 kg/m
89x89x3.5 = 9.07 kg/m
100x50x4 = 8.49 kg/m

I suppose 2kg of extra weight could be seen as not "a lot". I should stop talking in generalities, I suppose.
