When choosing floor tiles, many people focus on color, size, or price. In real daily use, however, the key factor that determines walking safety often comes from a less noticed technical measure: the slip resistance R rating (R-rating)<\/strong> or the COF (Coefficient of Friction).<\/strong><\/p>\n

These are essential standards in the building materials industry and directly impact safety in wet or moisture-prone areas such as bathrooms, gardens, kitchens, and swimming pool zones.<\/p>\n

1. What is the R rating? Why are anti-slip tiles graded from R9 to R13?<\/strong><\/p>\n

Under international standards, the R9\u2013R13 scale reflects how slip-resistant a tile surface is:<\/p>\n

R9<\/strong>: Low slip resistance, suitable for dry areas<\/p>\n

R10<\/strong>: Medium slip resistance, suitable for living rooms and indoor walkways<\/p>\n

R11<\/strong>: Good slip resistance, ideal for kitchens, terraces, and humid areas<\/p>\n

R12\u2013R13<\/strong>: Very high slip resistance, recommended for swimming pools, wet outdoor zones, and public spaces<\/p>\n

The higher the R rating, the better the grip and the lower the risk of slipping and falling.<\/strong><\/p>\n

Tiles with a higher R rating increase friction and improve footing in wet conditions. This is especially important for:<\/p>\n
