Yes, compliance depends on the specific setting and standard applied. For industrial access and machinery maintenance under BS EN ISO 14122-2, walkway floorings must prevent a 35mm ball from falling through. However, if a platform or walkway is positioned above a consistent working space where people are present, the flooring aperture must be restricted further to prevent a 20mm ball from falling through. Our plank profiles are engineered to balance efficient drainage with strict adherence to these safety dimensions.
