A seamed edge is basically just a safety edge where the burrs are removed. Technically, a seamed edge can have some chipping and still be considered “sellable” quality.
While a seamed edge allows for more safe handling, you should still wear gloves when handling the glass. Generally, seamed edges are only used for glass that is inserted or covered by molding or a frame.
It is not considered a “beautiful” edge and it is very rare for us to have an order for a top with a seamed edge. They are slightly less expensive but the price difference is minimal.
Some examples of edge types are over to the right. We also provide less common edges such as bevel, double bevel, dual bevel, and various degrees of miter edges.
