While I did not make them, my grates are factory and they look like angle iron in shape with the points down to fill with ash. They are still perfect and the arch is from 2001. I forget now, the grates are in sections and I think the sections are as if they are 3 V's each, V pointed down and an air space between each, but they are cast.
That is what I meant... Worded it wrong. The open side up, point down.
