Sizes & Precision

Why Dimensional Precision Matters

Tiles are manufactured under high temperatures, where shrinkage and minor dimensional variations are natural. Without control, these variations can affect both the visual outcome and installation quality.

Dimensional precision ensures that tiles behave as consistent, predictable units, enabling:

As tile sizes increase, especially in large formats and slabs, precision becomes critical rather than optional.

Understanding Rectification and Calibration

Dimensional precision in tiles is achieved through two distinct but complementary processes—rectification and calibration.

What is Rectification

Rectification is a mechanical finishing process in which tile edges are cut and ground after firing to achieve precise dimensions and sharp corners.

This process ensures:

Why Rectification is Required

During firing, tiles undergo shrinkage, which can lead to slight variations in size and edge geometry. Rectification corrects these variations, allowing tiles to be used in layouts that demand precision.

Impact on Design

Rectified tiles enable:

They are particularly suited for:

What is Calibration

Calibration is the process of sorting tiles into groups based on consistent thickness and dimensional range after firing.

Tiles are categorised so that each batch maintains:

Why Calibration is Required

Firing causes slight variations in tile dimensions. Without calibration, mixing tiles of different thickness can result in:

Impact on Installation

Calibration ensures:

Rectification and calibration work together to ensure both visual precision and structural consistency.

As tile sizes increase, dimensional precision becomes more critical.

Large format tiles and slabs require:

Rectification and calibration are therefore essential for:

Even with high precision:
