Cantilever Metal Rack and plans or show what you have made
I have some dry jarrah lenghts that needs to be racked to get it off the floor.
I have looked at the commercial Cantilever racking and it seems very light so thought about making my own.
Was looking at 1.5m centres for the three 2m high posts and 3 x 700mm arm lengths every 500mm in height.
Anyone have some photos or experience on metal size and thickness?

I think you'll be hard pressed to find someone that will give you an answer you're looking for.
The reason being, that if you made it to what they recommend and suggest, they then become liable, should anything go wrong.
Find out from the seller of the commercial made racking what the loading specs are, if they can't tell or give you it, then source a product that has the specs.
You might find that they will only supply the specs if they are erecting it, to Worksafe standards, had this happen with pallet racking in a factory.

Can't comment on the strength but will say as a long time hobby woodworker you need more posts. 1.5m apart isn't enough support unless the wood you are putting in it is cant sized. The wood will sag over time. I'd suggest 500mm between supports. It will pretty much eliminate sag and shorter lengths can still be racked. Up to you though.

Giving someone advice on a forum and then someone sueing them!!! First I have heard of that one, but hey if someone is that scared just say advice, not guaranteed to work
Plenty of specs for the commercial racking I have looked at so far. Nothing said about as to who erecting for said specs and to be honest I will be happy with my ability to erect shelving even if it voids the 'worksafe standards'.

Yes your right Pete I was trying to keep costs down, however if I have more posts it does dramatically decrease the load on each arm.
Currently at my above specs (1500mm arm spacing)I am looking at around 430kg per arm.
If I reduced it down to 750mm between each arm it would be 215kg
If I reduced down to 500mm between each arm it would be 143.5kg per arm.

Found the below link which has some good information. Does not have load limits, however I feel its going to easily support 215kg at 750mm centres.

So, just in case someone sees this thread for info.
I priced making up a rack out of the thickness and sized metal in the link I added a few posts above and its going to cost around $700+ to make (125x75x4mm posts, 50x50x4mm arms etc).
I received a quote for $1000 even from a racking supplier for a light duty '2.7m length at 900mm post centres 2.0m high, 3 x 700mm arms per post rated at 450kg' and decided for the price difference I will go pre-made.
Now time for some footings and awaiting the order
Thanks for all you assistance

I expect the commercial option will be much lighter wall section than you were planning on using, but probably much more carefully engineered to optimise performance vs. cost.
I plan to make up some kind of cantilevered rack in order to get stuff off the ground. In my case it'll be a bit less critical - heavy stuff (star pickets, random steel) will be on or near the bottom, light stuff (PVC pipe, timber) will be higher. I'm thinking of adding something to receive forklift tines so the whole rack can be moved about.
