Hi
I have a question on 100mm Cee section used for bearers and Joists
My question is, I am building a deck off the ground and was wondering what is the maximum distance between the bearers that I can go?
I am fixing the joists at 450 centers and will be using cypress decking.
There maybe a roof being fitted in the next 12 to 18 months.
Also the size of the deck is 10m x 10m. Sorry it isn't all woodwork but I hope you can overlook that to help me out.

100mm cold-drawn galvanised, or hot-rolled c-section? at what thickness?

Hi Brynk
Now you got me, I'm not sure i think maybe it is Cold-Drawn but I am not certain, I do know it is 1.5mm Galvanized but the other I am just guessing.
Thanks for your help

If it's 1.5 then it's cold-formed. I would check out strammit to see whether they have some span tables.
This will help,
Really good FAQ

I'm looking to build a deck and will use metal under, however the other week I saw the joists covered with a layer of rubber. This wasn't C section however, you could always replicate if prepared to spend the time cutting and fixing a rubber strip on top of the metal prior to fixing the timber decking. I could only assume this would alleviate the noise.
cheers.
