PROTERMINAL is a “L-shaped” profile in polished stainless steel INOX AISI 316LL/1.4404-V4A that can be applied on external corners of coverings. It can be used to close the perimeter of coverings, like a connection profile between step tread and riser of stairs coated with ceramic and natural stone tiles, and also as separation profile for floor coverings. Its particular section and the availability in three different heights make PROTERMINAL a much sought-after profile that allows a workmanlike application even in environments subject to high mechanical and chemical stresses.
