The contemporary look is attributed to the beveled edge. Bevels range from 1/2" to 2" in width, the most popular width being 1". The beveled edge is a 45° angle on the edge of the glass and can be applied to 1/4" to 3/4" glass thickness.
Usually applied in traditional style homes, the OG edge looks very much like a router edge as you would see on wood. This edge can only be applied to 1/2" and 3/4" thickness.
Flat Polish Edge
The flat polish edge leaves the edge perfectly flat while removing the sharpness of the glass. This can be applied to any thickness.
