What platform is used for these shelves/Staircases?

My first guess was Steampunk but the colors are reversed. Steampunk is gold platforms with grey supports.
And the steampunk shelves don't create those little hooks on the bottom of the shelves.

Those are Brass Shelves. They can be found in the Dungeon or can be crafted out of Copper Bricks at a Bone Welder in Ecto Mist.

Cheers Mate. I've been looking at every platform that I could think of for the past couple hours and couldn't figure it out. Almost gave up and just went with the steampunk ones.
