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 a variety of settings, from private to public contexts subject to intense foot traffic.
