Qualität & Sicherheit
Every single STONED climbing hold is tested before delivery according to DIN EN 12572-3 paragraph 6.3 and subsequently subjected to a sighting test and marked. Untested handholds are not sold. STONED climbing steps with the designation GR1 are not subject to the DIN regulations, they are the exception and are therefore exempt from the DIN regulations. Nevertheless, STONED sets the same high quality standards for the GR1 climbing steps and uses only highly solid and tested natural stones as well as the same high-quality resin structure.
