When purchasing tiles, it’s important to note their slip grading or “R” value (relating to the angle at which a person loses friction), which varies depending on their intended use.
Let's take a closer look:
A porcelain stoneware surface with “standard” slip resistance.
Suitable for entrances and stairways with outside access, in addition to restaurants and canteens, shops, GP surgeries, hospitals, and schools.
A porcelain stoneware surface with “average” slip resistance.
Suitable for shared bathrooms and showers, small catering kitchens, garages and basements.
A porcelain stoneware surface with “elevated” slip resistance.
Suitable for food production environments, workplaces with a high presence of water, and dry cleaners.
A porcelain stoneware surface with high slip resistance.
Suitable for areas where fatty foodstuffs are handled (dairy products, oils and sausages), large catering kitchens, industrial areas where slippery substances are used, and car parks.
