I don't build shelves, either. Why don't they support shelves?
The lock column group, on column group more trouble, first lock and lock the transverse bracing, bracing, lock when these two parts, and a sleeve parts more trouble, then these two parts is 600mm every one, but each company is not the same.
Just hang the beam, the beam will be hung according to the height of the drawing, and the shelves will be assembled.
If something that supports the shelf doesn't fit in, it's probably not good
