Yes if you are referring to a building with a cantilever protruding from the side of it.
But a Cantilever just describes what is forward of the front support, which is the section the cantilever begins at.
The rearward facing rod just ties it off the same as it being attached to a wall.
The wall is the vertical rod.
Yes the whole rack is not cantilevered, but then neither is a bridge that sits on land at each end.
A bridge has a cantilevered sections but that doesn't apply to the parts at each end that sit on land, never the less its still a cantilever bridge.
If the whole bridge was a cantilever then it would not sit on land, and then it wouldn't be a bridge.
And Zinc plating.
So cheap, no prepping they just hot tank it, takes 2 days.
I just take everything I make in steel to them now, don't bother with paints and powder coating anymore and far less sand blasting..
I found a guy nearby who has 4 metre long tanks and can do long stuff like this.
