I have these shelves and purchased on a similar deal. I believe the description of 70kg/shelf is wrong as mine are 350kg/shelf (they must have divided the per shelf rating by the 5 shelves….). Also this is in the reviews on the site so pretty sure its the same ones I have @350kg/shelf.
similar at bunnings (deeper but not as wide) is $129 and only 200kg/shelf
1220mm (W) x 400mm (D) x 1830mm (H).
350kg per shelf.
What kind of powder do they use?
