What is RECTIFIED tile ?
Rectified tile is fired tile–ceramic or porcelain tile–that has been mechanically cut or ground down to an exact size. Since it applies only to the tile’s edges, it is called an edge treatment.
Additionally, the edges are usually precisely cut at a square: a 90-degree angle.
Rectification is not considered better than other edge treatments; it is just a different treatment that allows for a different look.
A rectified tile is a tile whose sides have been mechanically finished and precisely cut for uniformity. It’s easier to align with other tiles of its kind, so less grout is applied between them when they’re laid down.
