Glulam Beam With "Teeth"

This beam caught our attention at the plant. It's unusual to see a beam with so many notches cut out at the top. 

This is a roof beam at the end of a large building and there are purlins that will sit in each notch. You can see this in the blueprint, below. No two notches are the same, because the roof has a slightly warped shape. 

The whole building has an interesting curved shape. There is another beam like this at the opposite end of the building, as well.
