Prostep SMA and SM are aluminium and natural brass profiles, designed to create and protect ceramic tile, marble, or stone steps. Prostep SMA and SM are laid at the same time as the covering, to assure they are set seamlessly into it. Moreover, thanks to the knurled surface, they are also non-slip certified to DIN 51131. These characteristics make Prostep SMA and SM suitable for various settings, from private to public contexts subject to intense foot traffic.
