Key Specifications

• Dimensions: 240 mm x 115 mm.

• Modular Design: This size is mathematically designed to be modular, often accounting for the width of the tile plus a standard grout joint (e.g., 240+10 mm grout). This makes it easier to achieve precise patterns for pool floor grids or lane markings.

• Material: Extruded porcelain or high-density ceramic. Extruded tiles are frequently used in this size because the extrusion process creates a very dense, low-porosity body that is ideal for long-term water immersion.

• Water Absorption: Extremely low (often ≤ 0.5\%), which is critical to prevent freeze-thaw damage in outdoor pools and to ensure the tile does not "pop" or lose adhesion over time due to water saturation.

Essential Characteristics

• Dimensional Accuracy: These tiles are usually "rectified," meaning they are cut with high precision after firing. This ensures that the grout lines remain perfectly straight, which is essential for the aesthetics of a professional-looking pool.

• Slip Resistance: Like the 244 x 119 mm format, this size comes in various finishes. The textured, antiskid versions are mandatory for safety in transition zones, such as beach entries or shallow-to-deep end slopes.

• High Traffic Durability: Designed for high-volume commercial use, they possess high mechanical strength, resisting the pressure of water depth and the heavy foot traffic of public swimming facilities.

• Chemical Inertness: They are completely unaffected by common pool chemicals and do not change color when exposed to sustained chlorine or salt-water systems.
