Hello,

I've searched high and low for this product and it's down to you now.

I want to build a metal stairway or ladder with a very steep angle.
And I wanted to use metal stair treads.

So, I'm looking for those metal stair treads that look like they are
pressed or stamped on sheet metal, the kind that have football
shaped holes with semicircle bumps on the top edge. That's
American football, or Canadian, not soccer.

Someone here always knows the answer, so thanks.
