Tiles can have different levels of rectification, depending on the desired finish and the production process. These include:

Rectified level: Typically, rectified tiles are more expensive because they require more labor and processing to achieve precise edges and a uniform surface. This option is particularly preferred in applications where high precision in installation and impeccable finished appearance is necessary.

Semi-rectified level: Tiles with a semi-rectified level may have an intermediate price, being less costly than rectified ones, but still offering a more uniform finish than non-rectified tiles.

Non-rectified level: Non-rectified tiles are often the most affordable option in terms of price, but they may have variations in size and shape, as well as less precise edges.

Each level of rectification offers a different look and quality, and the choice depends on personal preferences and the specific use of the tiles. It's important to consider not only the price but also the desired appearance and project requirements when choosing the level of tile rectification.
