Four common cases

The relationship of the dimensions U (distance between the end opening and the beam end) and T (distance between successive openings) is decisive. All other dimensions for a given beam follow from this.

Beam ends left ragged, U=T
	Simple and cheap, but not convenient to use.
	TOP
Beam ends left ragged, U>T
	Longer ends, but not very effective.
	TOP
Beam ends finished, U=T
	Nice finish, dearer due to extra cutting operation and material waste.
	TOP
Beam ends finished with infill plates, U>T
	Strong and rigid ends, but expensive.
