PROTERMINAL is a L-shaped profile in polished and satin finish stainless steel AISI 304/1.4301-V2A 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 two different finishes make PROTERMINAL a much sought-after profile that allows a workmanlike application even in environments subject to high mechanical stresses.
