During choose the alumina ceramic tiles, we often focus one the hardness and alumina content, the lower wear loss. But there is another one spec that your supplier may not mentioned for you: Dimensional Tolerance.

What will be happened when your tiles are warped, inconsistent in thickness, or have uneven edges?

1️⃣ When install of them, tiles with bad tolerances simply won't fit together. You end up with uneven grout lines, and a surface that looks patchy. The installers will spend hours grinding and shimming instead of actually laying tiles.

2️⃣ A warped tile doesn't sit flush against the others. It touches only at the high spots. When a rock or bulk material impacts that tile, the force isn't spread across the whole surface. It concentrates on those tiny high spots. Although the ceramic is strong, but it shatters under concentrated impact. How about the result? Cracks immediately upon startup.

3️⃣ Once one tile is slightly raised or cracks, it creates a leading edge for the material flow. That flow will hook under the raised edge, rip the tile off, and then get underneath the adjacent tiles. One bad tile doesn't just fail alone—it takes its neighbors out in a chain reaction.

Bad tolerance means bad adhesion. Bad adhesion means downtime. Always check your flatness and dimensional consistency before installation.
