Bevel - Stairway Angles And Math

A bevel can represent anything from a 5° angle to an 85° angle. They're used to make a transition and to ease into another part of the stairs or building.

The picture above shows a beveled piece of wood that was nailed on top of a 2 x 10 post band. If you don't want water or moisture to sit on top of a band of wood like this one, you will need to angle or bevel it.

Without the beveled piece of wood, the morning moisture will accumulate on top of the post band, seeping into any cracks or unpainted parts of the wood. This could eventually cause wood rots and possibly attract termites.

Bevels can be used through out the stairway, hand railing and even framing. It's not uncommon to find small bevels on wood or concrete stair treads.
